ACCESSING THE CONFIGURATION INTERFACE

For initial setup, the MDA should be connected to a network

and plugged into the wall with the On Mode switch set to EXT

CMD. Turn on the MDA by setting the master power switch to

On. The Power light on the front panel indicates that the MDA

has powered up. Once the LAN light on the front panel turns

blue or red, the MDA has connected to your network and ac-

quired a network address.

The MDA is congured using an interface accessed using a

web browser. Identify the MDA’s IP address to proceed. You

can discover the MDA’s IP address using the ARC Genesis

software (available on AnthemARC.com). Start the program,

choose Launch ARC, and hover your mouse cursor over the

MDA, wait for a second, and it shows the IP address in the de-

vice discovery screen. Note that the last few characters of the

unit’s name correspond to the end of the MAC address printed

at the back of the MDA.

To access the MDA’s conguration interface, open a web

browser (we recommend Chrome or Safari), type the IP ad-

dress into the browser’s address bar, and hit enter.

When installing more than one MDA, there are multiple IP ad-

dresses. To identify each MDA, use a web browser to connect

to the rst one and click General > Preferences > Unit ID. The

ID light on the back panel ashes as will the Power indicator

on the front of the MDA. The MAC Address displayed under

General > Information matches the unique MAC Address

printed on the back of the MDA.

CONFIGURING THE MDA

1. Access the conguration interface by entering the MDA’s IP

address in a web browser’s address bar.

2. General > Information > Device Name: Create a name

for the MDA and click Apply.

3. Inputs > Analog 1 (or other input) > Input Name: Create

a name and click Apply

4. Repeat for additional inputs.

5. Zones > Zone 1 > Zone Settings >

a. Zone Name: Create a name and click Apply.

b. Input Source: Choose the input you want to hear in

this zone.

c. SpeakerProle:Select the type of speaker connected

or keep them as Generic type if not shown in the list.

6. Zones > Zone 1 > Subwoofer > Subwoofer: When there is

a sub connected to the zone’s Sub Out, set the toggle to on.

7. Repeat for additional zones.

RUNNING ANTHEM ROOM CORRECTION (ARC

)

Once speakers and subwoofers are connected and cong-

ured, and sources and zones are named, you can run room

correction for each zone that is being used. Download the ARC

Genesis software from AnthemARC.com and follow the on-

screen instructions. See section 4 for additional details.

CONTROLLING THE MDA

Play music using one of the sources connected to the MDA. In

most installations, a custom integrated control system is used

to adjust the volume and change which source is playing in

which zone. You can also adjust volume and change inputs

using the conguration interface.

• Access the conguration interface by entering the MDA’s IP

address in a web browser’s address bar.

• Zones > Zone 1 (or another zone) > Zone Settings > Input

Source: Choose the input you want to hear in this zone.

• Zones > Zone 1 (or another zone) > Volume > Zone Vol-

ume: Adjust the volume here.

1.8 SETTING UP A CONTROL SYSTEM

MDAs are compatible with IP and RS232 command protocols. A

detailed command set and discovery protocol are available on

MartinLogan.com. A variety of MartinLogan developed automa-

tion drivers are also available for download free-of-charge from

our web site for easy integration into a smart-home powered by

Crestron, Savant, and other similar controllers.

For optimum performance and enjoyment, your MDA should

be appropriately set up. If you’re using a subwoofer or sub-

woofers, ARC (Anthem Room Correction) sets crossovers and

levels for a perfect blend with the main speakers. The rest of

the settings mostly relate to your preferences. Please fully

congure all zones with the proper output modes (single-end-

ed, stereo or mono bridge), speaker prole and subwoofer

settings (present or not, active or passive) before running ARC.

2.1 ACCESSING THE USER INTERFACE

For initial setup, the MDA should be connected to a network

and plugged into the wall with the On Mode switch set to Auto.

Turn on the MDA by setting the master power switch to On.

The Power light on the front panel indicates that the MDA has

powered up. Once the LAN light on the front panel turns blue

or red, the MDA has connected to your network and acquired

a network address.

2.2 FINDING THE MDA’S IP ADDRESS

The MDA is congured using an interface accessed using a

web browser. Identify the MDA’s IP address to proceed.

You can discover the MDA’s IP address using the ARC Gene-

sis software. Start the ARC program on a PC or Mac, choose

Launch ARC, and hover your mouse cursor over the MDA, wait

for a second, and it shows the IP address in the device discov-

ery screen.

We also recommend using Fing, a free network device detec-

tion app available on iOS, Android, and Windows. This app

identies devices on a network and shows their IP addresses.

These identify with MDA8 or MDA16 or MartinLogan.

To access the MDA’s conguration interface, open a web

browser (we recommend Chrome or Safari), type the IP ad-

dress into the browser’s address bar, and hit enter.

2.3 IDENTIFYING MULTIPLE MDAs

When installing more than one MDA, there are multiple IP ad-

dresses. To identify each MDA, use a web browser to connect

to the rst one and set General > Preferences > Unit ID to On.

The ID light on the MDA’s back panel and the Power indicator

on the front ash. The MAC Address displayed under General

> Information also matches the unique MAC Address printed

on the back of the MDA. Note that the last few characters of

the factory default unit’s name correspond to the end of the

MAC address printed at the back of the MDA.

2. THE USER INTERFACE

Zones: Adjusts the settings of individual zones, allowing

zone naming, source selection, mode setup, listening

mode, speaker prole, level adjustment, tone control, vol-

ume conguration, and subwoofer setup. The top of the

page shows the individual zones.

Inputs: Allows input naming and level balancing (trim). See

section 2.5 for additional details.

les saved on your PC or Mac. Also allows storing and load-

ing from 2 local storage areas (user’s or installer’s settings).

See section 2.10 for additional details.

The Zone taskbar shows available zones and highlights the

currently selected zone (MDA16 shows 8 zones, and MDA8

shows 4 zones). Stereo Bridge and Subwoofer Powered

by Zone 2 (4, 6, or 8) turn the even-numbered zones grey,

indicating they are disabled. In this case, settings and con-

trols of the odd-numbered zone transfer automatically to

the even-numbered zone.

Mono Bridge: Sets a single zone into a high output mode

for a single speaker. The listening mode is automatically

set to Mono when selecting Mono Bridge mode. See sec-

tion 3.4 for additional details.

Stereo Bridge: Sets a zone pair (1 & 2, 3 & 4, 5 & 6, or 7 & 8) into

2.4 ZONES

The user interface design is subject to change.

a left and right conguration. When activated, the even-num-

bered zone turns grey, and the odd-numbered zone controls

the settings. This setting allows a high output mode for a pair

of speakers with each zone acting as a discrete channel. The

listening mode is automatically set to stereo when selecting

Stereo Bridge mode. See section 3.5 for additional details.

Zone Power: Toggles the zone between active and stand-

by. When set to Auto mode and music is playing in that

zone, the toggle automatically goes back ON when analog

or digital audio is detected.

ARC: Turns ARC on and o for the zone (only available if ARC

software has been used to upload corrections for the zone).

Zone Name: Assign a name to the zone (up to 16 charac-

ters) and click Apply to save this setting. The names of the

zones appear in ARC, allowing easy identication.

Input Source: Selects the desired input source. An input

can be assigned simultaneously to multiple zones. If you

are not using the built-in matrix switching this remains

static until altered either through the web interface or IP/

RS232 control. Selecting a source here does not prevent

you from changing source dynamically during use through

a compatible home automation system.

Listening Mode > Stereo: The default listening mode. The

audio plays in stereo.

Listening Mode > Mono: Sums the left and right channels

and sends identical signals to both speakers.

Speaker Prole: Selects a specic in-wall or in-ceiling

speaker model for each zone. Selecting a particular model

allows the DSP to optimize the EQ and limiter settings. En-

able a Speaker Prole using the toggle button located right

of the drop-downs. If you don’t know the model of your

speakers, or if your speakers are not listed, select Generic.

Zone Volume: Adjusts the level of the zone. Each zone has

independent volume control. Please note that selecting

a volume level in the Web UI does not prevent you from

changing volume levels dynamically during use with a

compatible automation system.

Power On Volume: The volume level for the zone when it

turns on.

Max Volume: Prevents the volume of the zone from ex-

ceeding the desired level. Please note that an external vol-

ume adjustment cannot override this level. If an automation

system attempts to adjust the volume level higher than the

max volume setting the MDA ignores the command.

Mute: Mutes the zone.

Bass / Treble: Allows ne-tuning of the relative bass and

treble levels of the system. Please note that if using a sub-

woofer, the subwoofer level adjusts the subwoofer level

relative to the main channels.

Left / Right: Adjusts the level of the left and right channels

to set the balance.

Subwoofer: Activates and deactivates the subwoofer and

bass management. Subwoofer output does not function

unless this toggle is enabled. By default, the subwoof-

er signal is output using the Sub Out RCA connection for

the zone. If using a subwoofer, enable this before running

ARC. See section 3.6 for additional details.

Crossover: Sets the crossover point between the sub-

woofer and the main speakers. When using ARC, this value

is automatically set. To change the crossover value after

running ARC, modify the crossover setting in ARC and then

re-upload. The crossover should only be manually adjust-

ed if you are not using ARC.

Sub Level: Adjusts the level of the subwoofer relative to the

mains. When using ARC, this value is automatically set. Unlike

the Crossover setting, manually changing this value after run

ning ARC will not negatively impact subwoofer integration.

Sub Phase: Adjusts the phase of the subwoofer relative

to the main channels. Phase is adjustable from 0-180 de-

grees. If a value higher than 180 degrees is required, ad-

just Subwoofer Phase in combination with Sub Polarity for

a full 360-degree range of adjustment. When using ARC,

this value is automatically set using the Automatic Phase

Adjustment tool.

Sub Polarity: Adjusts the polarity of the subwoofer to ei-

ther 0 or 180 degrees. When selecting 180 degrees, the

subwoofer signal is inverted when compared to the main

channels. As a general guide, set Phase and Polarity to 0 if

the subwoofer is near the front speakers and set Phase to

0 and Polarity to 180 if the subwoofer is near the back of

the room. When using ARC, this value is automatically set

using the Automatic Phase Adjustment tool.

tive zones to operate together for a stereo pair of speakers

and a dedicated passive subwoofer connected in bridge

mode (and must be connected as such on the rear pan-

el of the unit). When engaged, all adjustments are made

using the controls in the odd-numbered zone, and the

even-numbered zones controls are disabled. For example,

when engaged, Zone 1 controls both left and right speak-

ers connected to Zone 1 and the subwoofer connected to

Zone 2. Enable this feature before running ARC. See sec-

tion 3.7 for additional details.

3. CONNECTIONS AND BACK PANEL CONTROLS

3.1 LOCAL AREA NETWORK CONNECTION

A network connection is required to access the conguration

interface, run Anthem Room Correction, and use IP control.

Connect to your router using an Ethernet (CAT5) cable.

3.2 SPEAKER CONNECTIONS

Depending on the level of the input signal, the volt-

age at the outputs can be high enough to cause

electric shock – be sure that power is o when con-

necting or disconnecting anything. As well, be sure

to use speakers rated for use with this MDA – an

overdriven speaker can pose a re hazard.

MDAs oer several options for connecting speakers and pas-

sive subwoofers:

• Stereo speakers hooked to a single zone.

• For more power, a zone can be bridged to drive a single

speaker in either mono or stereo mode. Bridge mode uses

the left and right output to drive a single speaker. Mono

bridge mode uses a single zone whereas stereo bridge

uses two consecutive zones to drive a stereo pair.

• Bridge a zone to power a passive subwoofer to comple-

ment a stereo pair.

When stereo bridge is enabled, you must always use two con-

secutive zones (zones 1/2, 3/4, 5/6, or 7/ 8).

It is possible to mix-and-match zone congurations within a

single MDA. For example:

• Zone 1 (Kitchen): left & right speakers

• Zone 2 (Bathroom): left & right speakers

• Zones 3/4 (Den): left & right speakers bridged for more

power in stereo mode

• Zone 5/6 (Living Room): left & right speakers with a pas-

sive subwoofer (connected to Zone 6)

• Zone 7 (Hallway): left & right speakers bridged for more

power in mono mode

• Zone 8 (Bedroom): left & right speakers with a powered

subwoofer (connected via Zone 8 Sub Out RCA)

3.3 CONNECTING STEREO SPEAKERS

Connect a pair of speakers to a zone using a Euroblock (also

known as a Phoenix

) connector. These connectors are in-

cluded with the MDA and come preinstalled. Euroblock con-

nectors accept speaker wire up to 12 gauge. Use speakers as

low as 4 Ohms in this conguration.

1. Remove the zone’s Euroblock connector from the MDA by

gently pulling it until it releases.

2. Use a small slotted screwdriver to loosen and tighten each

contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection on the left speaker to the

positive (L+) contact on the Euroblock connector as indi-

cated by the printing located on the MDA (above the con-

nector) or on the connector itself.

4. Connect the black (–) connection on the left speaker to

the negative (L–) contact on the Euroblock connector as

indicated by the printing located on the MDA (above the

connector) or on the connector itself.

5. Repeat for the right channel.

6. After attaching speaker wires to the Euroblock connector,

insert it into the MDA by gently pressing it into place.

ANALOG OUT

3.4 CONNECTING MONO SPEAKERS

USING ONE BRIDGED ZONE

A zone set to mono mode can be used to drive a single speak-

er, allowing the MDA to deliver more power per channel. En-

abling mono bridge sets the listening mode to mono automat-

ically. Bridge mode only supports speakers rated for 8 Ohms

or higher. Any zone set to Mono Bridge can use an active sub

connected via the zone’s Sub Out. An odd-numbered zone set

to Mono Bridge can use the matching even-numbered zone to

power a passive subwoofer using the Powered by Zone 2 (4,

6, or 8) setting.

Speaker Connection:

1. Remove the Euroblock connector by gently pulling it until

it releases.

2. Use a small slotted screwdriver to loosen and tighten each

contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection of the speaker to the pos-

itive (R+) contact on the Euroblock connector as indicated

by the printing located on the MDA (below the connec-

tor).

4. Connect the black (–) connection of the speaker to the

negative (L–) contact on the Euroblock connector as indi-

cated by the printing located on the MDA (below the con-

nector).

Enabling Bridge Mode:

1. Enable bridge mode via the web interface by going to

Zones and selecting Mono Bridge in the desired zone. The

Listening Mode is set automatically set to Mono.

ANALOG OUT

L+R

3.5 CONNECTING STEREO SPEAKERS

USING TWO BRIDGED ZONES

Using two zones to drive a single stereo pair of speakers allows

the MDA to deliver more power per channel. When bridging,

two consecutive zones are used to drive the stereo pair (Zones

1 and 2, 3 and 4, 5 and 6, or 7 and 8). Bridge mode only supports

speakers rated for 8 Ohms or higher. The only option to use a

subwoofer in this conguration is the use of an active sub con-

nected via Sub Out, and the MDA will no longer respond to IP or

RS232 commands for the even-numbered zone.

Left Speaker Connection:

1. Remove the Euroblock connector from the odd-num-

bered zone by gently pulling it until it releases. The left

speaker connects the odd zone.

2. Use a small slotted screwdriver to loosen and tighten each

contact on the Euroblock when inserting the speaker wire.

Connect the red (+) connection of the left speaker to the pos-

itive (R+) contact on the Euroblock connector as indicated by

the printing located on the MDA (below the connector).

Connect the black (–) connection of the left speaker to the neg-

ative (L–) contact on the Euroblock connector as indicated by

the printing located on the MDA (below the connector).

5. After attaching speaker wires to the Euroblock connector,

insert it into the MDA by gently pressing it into place.

Right Speaker Connection:

1. Repeat for the right speaker by making a similar connec-

tion on the next even zone (for example, if you just at-

tached the left channel to zone 1, connect the right speak-

er to zone 2).

Connect the red (+) connection of the right speaker to the pos-

itive (R+) contact on the Euroblock connector as indicated by

the printing located on the MDA (below the connector).

Connect the black (–) connection of the right speaker to the

negative (L–) contact on the Euroblock connector as indicated

by the printing located on the MDA (below the connector).

4. After attaching speaker wires to the Euroblock connector,

insert it into the MDA by gently pressing it into place.

Enabling Bridge Mode:

1. Enable bridge mode via the web interface by going to

Zones and selecting Stereo Bridge in the desired zone.

Controls for the even-numbered zone become unavail-

able, and the odd-numbered zone now controls settings

for both speakers.

3.6 SUBWOOFER OUTPUTS

If you’re using this MDA to power a passive (non-powered)

subwoofer refer to the next section. To connect a powered

subwoofer, use an RCA cable, connect a zone’s Sub Out to a

powered subwoofer LFE input, and enable the subwoofer using

Zones > Subwoofer. If the powered subwoofer doesn’t have

an LFE input, connect to either the left or right input and set

the sub’s low-pass lter (commonly referred to as crossover) to

its highest or bypass setting. Please refer to your subwoofer’s

manual for specic connection and control setting instructions.

This control also enables the high pass lter on the left and

right outputs. If you are not using ARC and do not have a sub-

woofer connected, you can enable this control and set the

crossover frequency. This will avoid overloading speakers that

don’t support a full-range signal.

3.7 CONNECTING A PASSIVE

(NON-POWERED) SUBWOOFER

USING A BRIDGED ZONE

If using a passive (non-powered) subwoofer, an even-num-

bered zone can be congured to power the sub. This mode

only supports subwoofers rated at 8 Ohms or higher. The

even-numbered zone is bridged to provide more power. For

example, in Zone 1 connect the left/right speakers using the

stereo pair conguration and in Zone 2 connect the passive

subwoofer by following these instructions:

1. Remove the zone’s Euroblock connector from an even

zone of the MDA by gently pulling it until it releases.

2. Use a small slotted screwdriver to loosen and tighten each

contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection of the subwoofer to the

positive (R+) contact on the Euroblock connector as indi-

cated by the printing located on the MDA (below the con-

nector).

4. Connect the black (–) connection of the subwoofer to the

negative (L-) contact on the Euroblock connector as indi-

cated by the printing located on the MDA (below the con-

nector).

5. After attaching subwoofer wires to the Euroblock connec-

tor, insert it into the MDA by gently pressing it into place.

Using the web interface enable the subwoofer bridge mode in

the Zones > Subwoofer menu and then enable Powered by Zone

2 (4, 6, or 8). Note that the even zone parameters become un

available when this mode is enabled. The odd zone screen de-

termines the input source, level, crossover, phase, and polarity.

SUB

3.8 DIGITAL INPUTS

Stereo digital audio sources can be connected using coaxial or

optical cables. The MDA16 has two digital optical inputs, and

two digital coaxial inputs and The MDA8 has one digital optical

input. All of these inputs support the PCM stereo format (up

to 24-bit / 192kHz). If using sources that have an option for

selecting between PCM and Bitstream (or Dolby Digital) audio

output, select PCM. If the source outputs a non-PCM stream

(such as a Dolby or DTS stream), the audio will mute.

3.9 DIGITAL OUTPUT (MDA16 ONLY)

The digital optical output on the MDA16 provides a repeat

function to feed an additional MDA (or any other component

that accepts digital optical input). This output supports up

to 24-bit/192kHz and can be congured to output any of the

MDA’s digital inputs (including digital coaxial). Select any of the

digital inputs via the web interface by clicking on Digital Out

Source in the General > Preferences screen and selecting the

appropriate digital input.

3.10 ANALOG INPUTS

Connect stereo analog sources using RCA cables. The MDA16

has eight stereo RCA line inputs. The MDA8 has four stereo

RCA line inputs.

3.11 ANALOG OUTPUTS (MDA16 ONLY)

The MDA16 has two stereo analog RCA line outputs. Any audio

source connected to the Analog 6 input passes unaltered to

the Analog 6 Out. Any audio source connected to the Analog

7 input passes unaltered to the Analog 7 Out. These act as

“pass-throughs” and work even when the MDA is in standby

or powered o.

3.12 POWER

Insert a power cord into the MDA’s AC input. Plug the cord into

a wall outlet. Ensure that the AC supply matches the voltage

rating shown on the back of the MDA. The 230V models sup-

port voltages from 220V to 240V.

3.13 TRIGGER CONNECTIONS

The trigger connection allows the MDA to be turned on or o

via the trigger input. When either Trig In 3.5mm (1/8”) mini-

jack receives power (5–24 volts DC or AC) from an upstream

component, the MDA turns on (Auto-On delay applies). When

it stops receiving power, the MDA turns o immediately. The

second Trig In jack allows you to run a cable out to daisy-chain

and trigger additional MDAs. For this function to work the On

Mode switch must be set to Trig. Please note, do not connect

triggers from two upstream components at the same time. Al-

ways use one as an input and one as an output.

The trigger also works with the On Mode switch set to Auto.

See section 3.15 for additional details.

3.14 RS-232 CONNECTION

The RS-232 connection allows connection to a compatible con-

trol system. The control system should be congured to use

115200/8-N-1, no ow control, protocol. The cable connection

should be one to one.

3.15 ON MODE SWITCH

With the three-way switch located on the back panel, you set

the way the MDA turns on and o.

• Trig: This sets the MDA to turn on and o when it receives

a signal on its Trig In connection. See section 3.13 for ad-

ditional details.

• Auto: This sets the MDA to turn on when it detects an in-

coming signal on any of its digital or analog audio inputs.

When the MDA stops detecting all incoming audio signals,

it enters standby mode after approximately 20 minutes

(by default). O and on times can be adjusted via the web

interface. Go to General > Preferences > Auto-O Delay

and Auto-On delay. The trigger input also works in this

mode. The MDA will turn on when a signal is applied to Trig

In, even if no audio signal is detected. The unit will enter

standby mode after the Auto-O delay once the trig signal

is removed and no audio signal is detected.

• Ext Cmd: This sets the MDA to ONLY turn on and o when

it receives commands from an IP or RS-232 control system.

Note that commands can be sent in any mode of operation.

For example, the volume may be changed whether the switch

is set to Auto or Trig. You will not be able to turn on a zone

using a command if in Trig mode and the trigger input is

de-asserted, but a turn on command will work if the On Mode

switch is set in Auto mode.

3.16 MASTER POWER SWITCH

This switch is wired directly to the AC mains and turns on and

o all power going to the MDA.

3.17 DHCP OR FACTORY IMAGE RESET

This reset button allows you to manually reset the MDA’s net-

work connection DHCP settings or restore the MDA to the

original factory image. See section 7 for additional details.

3.18 ID INDICATOR

When multiple MDAs are in a rack, you can quickly identify

each MDA by making use of the ID indicator. Use a web brows-

er to connect to the control interface of the rst MDA and en-

able Unit ID under General > Preferences. The ID light on the

back panel ashes as will the Power indicator on the front of

the MDA. You can also match the MAC Address shown under

General > Information with the unique MAC Address printed

on the back of each MDA.

3.19 ARC MICRO-USB CONNECTION

If a local area network connection is not available the Anthem

Room Correction (ARC) software can still connect to the unit

by making use of this micro-USB connector. Connect a USB

type A to micro B cable between the MDA and your PC or Mac.

3.20 CHASSIS GROUND

The MDA is powered using a double-insulated power cord and

therefore does not have an earth ground connection to avoid

hum. If an earth ground connection is required, or if connect-

ing to another chassis ground, you can connect a wire using

the thumbscrew.

3.21 FUSE

To replace the fuse, rst set the Master Power switch to O

and disconnect the power cord, Using a small slotted screw-

driver, remove the fuse cap and replace the fuse with a match-

ing type and rating as shown at the back of the unit.

4. ANTHEM ROOM CORRECTION (ARC

)

Please visit AnthemARC.com for detailed information about

using Anthem Room Correction.

The most signicant detriment to the sound of an audio sys-

tem is almost always the room it resides within—especial-

ly true in the realm of bass. Even in a professionally treated

sound room, bass can quickly become boomy or anemic. An-

them Room Correction helps audio systems sound their best

in any space. ARC oers a robust suite of tools to tame your

wild sonic frontier, whether you have a tricked-out home the-

ater, a traditional living room with carpet and thick drapes, or

a modern oor plan with large open spaces and acoustically

reective furniture and windows.

Have you ever tested the acoustics in an empty room by whis-

tling or clapping? It brings to mind how sound is aected by

a room’s size, structure, and contents. Even when using op-

timally positioned speakers of exceptional quality, the room

negatively impacts sound quality considerably. Surfaces such

as windows and furnishings and the geometry of the walls,

oor, and ceiling add unwanted resonance and coloration,

making the bass either boomy or less punchy, voices less nat-

ural, and the dialogue less intelligible. The eect on frequency

response is typically ±6 dB in the midrange and ±10 dB at low

frequencies.

To compensate for this and to optimize the in-room response

of your speakers, Anthem Room Correction measures the out-

put of each speaker relative to the listening area then, through

a series of calculations, adjusts its output. Not only does ARC

correct peaks and dips in a speaker’s frequency response, but

it also preserves the benecial acoustic attributes of a room—

attributes based on proven psychoacoustic science (the study

of how humans hear and experience sound).

In the sample curves provided here, the red curves represent

the in-room response before correction, as an average from

ve measurement positions, whereas the green ones show re-

sponse with equalization applied. The black curve represents

the target response. In this case, a subwoofer and bass man-

agement are also in use.

The default correction range, as shown below, is 5,000 Hz.

This range can be changed to a higher or lower frequency if

desired, although raising it is not recommended. At higher fre-

quencies, the microphone becomes directional, thus aecting

measurement accuracy.

Note the rise in the measured and corrected response below

200 Hz. This rise shows the amount of room gain. ARC pre-

serves the natural room gain of the room or allows you to ad-

just the amount of room gain if you wish.

The subwoofer graph may imply that the subwoofer plays up

to the highest frequency shown, but what it plays depends

on what the other channels send to it as determined by their

crossover setting. The subwoofer graph shows the available

correction range, which is not necessarily the range that other

channels send to it through bass management.

4.1 USING ARC WITH AN MDA

In addition to correcting the acoustic response of subs

and speakers in each zone, ARC also:

• Adjusts the left/right balance of the speakers.

• Sets the crossover point between the speakers and sub-

woofer (do not manually change this after running ARC).

• Adjust the subwoofer’s level relative to the speakers.

• Sets the phase and polarity of the subwoofer relative to

the speakers (requires the additional step of running the

Automatic Phase Adjustment tool after uploading correc-

tions to the MDA).

Before using Anthem Room Correction:

• Name the MDA.

• Set up and name the zones.

• Enable subwoofers (if applicable).

To use Anthem Room Correction:

1. Download and install the program from AnthemARC.com.

2. Start the program and select Launch ARC from the rst screen.

3. Select the MDA from the device discovery screen.

4. Select the zone you wish to measure from the drop-

down list.

5. Follow the on-screen instructions to measure the zone,

calculate correction curves, and upload them to the MDA.

6. After uploading the corrections, run the Automatic Phase

Adjustment tool from the Review Summary & Upload

screen. This tool sets the phase of a subwoofer to opti-

mize its integration with the speakers.

5. UPDATING FIRMWARE

Blue Blue O MDA enabled, no music detected.

Blue Normal operation: MDA enabled, music playing.

Blue

ashing

Blue Zone over temp. The module for a zone pair has exceeded a critical point, and the zone pair is turned o to protect the

module. After sucient cooling time (typically a few minutes) it will automatically resume normal operation if the system

is set to Auto or Trig mode. In Ext Cmd mode, a command is required to turn it back on.

Red

ashing

Zone overcurrent has been detected, either due to a low impedance speaker or a faulty speaker. The aected zone will

continue to ash its LEDs for at least 10 seconds. Normal operation will resume automatically if the overload is removed.

Blue

ashing

Zone thermal foldback. The MDA’s die (chip) temperature is approaching a critical point. The aected zone will continue

to ash its LEDs for at least 10 seconds. If this state is allowed to persist, the MDA will continue to operate but automati-

cally reduces the output level on that zone to protect itself.

Red Red

ashing

Red

ashing

High-frequency detect. The MDA detected an abnormal high-frequency signal on one of the speaker terminals and

shut down that zone to avoid damaging tweeters. The zone at fault will continue ashing its LED’s red. To clear this fault

condition, cycle the power by turning o AC power. Wait 1 minute before turning the MDA back on or until the front or

rear LAN jack LEDs go o. If the fault condition returns after a power cycle, the MDA requires service.

Red

ashing

O O PSU under voltage. This fault can be caused by:

• Inadequate AC line voltage

• Excessive power drawn by the combined zone outputs

• Failure of the PSU to reach operating voltage at power-up

For the rst two cases, normal operation resumes automatically in Auto and Trig mode, or by issuing a command when

in Ext Cmd mode. In the third case, an AC power re-cycle is required.

Blue

ashing

Blue

ashing

Power supply over temp. Total combined power output is excessive for the power supply. All zones are immediately

turned o, and all their LEDs will be ashing blue for a short period while the fan runs at high speed. Then the system will

power down and enter network standby. If in Auto or Trig mode, the system will automatically resume operation once it

has cooled suciently (normally several minutes). If in Ext Cmd mode a command is required to turn back on the unit.

Software error. If there is an unrecoverable software error, all the LEDs on the top row will ash blue, and all the

bottom row will ash red. It can only be cleared by cycling power. Please note, when power cycling, turn the unit o for

a minute before turning it back on or until the front or rear LAN jack LEDs go o to make sure that all capacitors have

discharged.

DC Fault. The MDA detected an abnormal DC oset on one of the speaker terminals. The entire system shuts down

automatically to protect the speakers; the Zone at fault (and its twin) will continue ashing its LED’s red. To clear this fault

condition, cycle the power by turning o AC power. Wait 1 minute before turning the MDA back on or until the front or

rear LAN jack LEDs go o. If the fault condition returns after a power cycle, the MDA requires service.

power-up

See text See text Initialization error has occured when the unit powered up. The Power LED will ash red and the front or rear LAN LED

will ash blue. The top and bottom LEDs for one of the zones will be ashing red to report the fault:

• Zone1(bothashingred):DSP failure

• Zone2(bothashingred):ADC failure

• Zone3(bothashingred):SPDIF receiver failure

• Zone4(bothashingred):DAC failure

To clear this fault condition, cycle the power by turning o AC power. Wait 1 minute before turning the MDA back on or

until the front or rear LAN jack LEDs go o. If the fault condition returns after a power cycle, the MDA requires service.

7. TROUBLESHOOTING

Manually Resetting Network IP Mode to DHCP

If errors occur when adjusting static IP settings, the MDA can

be manually set back to DHCP. Using a pin or straightened

paperclip, depress the DHCP Reset / Factory Image button for

about 1 second. The blue ID LED turns on to indicate the se-

lection of DHCP. It should take a few seconds for the server to

reassign an address.

Manually Loading the Factory Image

This function restores the MDA to its original factory image.

Any rmware updates you have done are lost and replaced by

the version programmed at the factory. The current settings,

the saved user settings, and the saved installer settings are

deleted and replaced by the factory default. ARC corrections

are also erased from local memory.

To reload the original factory image and remove all settings, set

the Master Power switch to O and wait until the lights above

the Network connection stop ashing (this may take over a

minute if the unit was in standby). Using a pin or straightened

paper clip depress and hold the DHCP Reset / Factory Image

button while turning On the Master Power switch. Continue

to depress the button until the blue ID LED ashes twice. The

Factory Image reloads (this takes about a minute). Front panel

indicators turn blue and red using a chasing pattern while the

reload is taking place.

8. FREQUENTLY ASKED QUESTIONS

HowdoIndtheIPaddressofmyMDA?

We recommend using Anthem’s ARC Genesis software or us-

ing a utility called Fing. See section 2.2 for additional details.

I’m connecting my DVD player to the MDA using a TOS in-

put, but even if the disc is playing, I do not hear any sound.

The MDA digital input only supports a PCM stream. Access

your DVD player setup menu and change the output format

to PCM.

I have a subwoofer connected to the MDA using an RCA

jack, but even if I’m playing music with lots of low-fre-

quency content, the subwoofer does not work.

Enable the subwoofer (the default setting is o). See section

2.4 for additional information.

I’m sending commands to the MDA using the serial port,

but the MDA does not react.

Make sure to congure your controller to 115200/8-N-1. Make

sure to send the terminator “;” at the end of the command. CR/

LF are not required.

I’mconguringapairofspeakersinstereobridgemode

on zones 1 and 2. I have my left speaker on zone 1 and

my right speaker on zone 2. My source’s left channel is

attached to the Analog 1 left input and its right channel

connected to the Analog 2 right input. I only hear sound

fromtheleftchannel.WhatamIdoingwrong?

Inputs and speakers (even bridged speakers) operate inde-

pendently of one another. Attach your source’s left and right

channels to the Analog 1 inputs and set Zone 1’s Input Source

to Analog 1. When in bridge mode, Zone 1 becomes the “mas-

ter,” so source selection, volume change, tone control, are all

done by accessing the Zone 1 panel. All settings in Zone 2 set

before selecting Stereo Bridge mode are no longer relevant.

My CD player analog output level cannot be controlled

and defaults to a very high level (2 Vrms). When playing

music, the MDA seems to be clipping very often. How can

thisbeavoided?

The MDA allows you to change the trim of any source. Select

the Inputs pane and set the trim level between -6 dB to -9 dB

for the source where your CD player is connected.

How does the MDA work when the On Mode switch is set

toAuto?

When the MDA is in standby, it monitors all analog and digital

connectors to check if the unit needs to turn on:

• Analog connectors are monitored for a signal higher than

-60 dBV (1 mVrms).

• Digital connectors are monitored by checking if there

is any bit toggling on the coaxial or Toslink inputs. The

MDA doesn’t check for a specic level to achieve <1/2W in

standby, only activity.

When in operation, the active channels are monitored. When

the level drops below -60 dBV (for either analog or digital in-

puts) for the amount of time programmed in the Auto-O de-

lay, the zone turns o. If all zones are o, the unit will go in

standby.
