What is in the box
Here is what is in the box besides all the shipping foam:
One MX100 A/V Processor
One accessory package including:
• Microphone with attached cable
• Microphone stand
• 1/2 inch male to 5/8 inch female adapter
One hardware package:
• Two Side Rack Mounting brackets
• 4 at head Philips screws 6-32x1/4”
• 4 at head Philips screws 8-32x1/4”
One manual package including this manual
One HR085 Remote Control
One AC power cord
Where to put it
The MX100 can be placed upright on a table or
shelf, standing on its four feet. It also can be custom
installed in a piece of furniture or cabinet. The four
feet may be removed for custom installations. The
four feet together with the mounting screws should
be retained for possible future use. Do not use
dierent size screws when re-installing the feet. With
the feet removed, the MX100 requires a ventilation
cutout. Dimensions for the panel cutout and bottom
ventilation cutout are shown in “Figure 02– Custom
cutout dimensions” on page 7.
Always provide adequate ventilation for your
MX100. Cool operation ensures the longest possible
operating life for any electronic instrument. Do not
install the MX100 directly above a heat generating
component such as a high-powered amplier. If all
the components are installed in a single cabinet, a
quiet running ventilation fan can be a denite asset in
maintaining all the system components at the coolest
possible operating temperature.
A custom cabinet installation should provide the
following minimum spacing dimensions for cool
operation:
• 2 inches (5.1cm) above the top
• 2 inches (5.1cm) below the bottom
• 1 inch (2.5cm) on each side of the MX100 so
that airow is not obstructed
• 20 inches (50.8cm) depth behind the front panel
• 1-7/16 inch (3.7cm) in front of the mounting
panel for knob clearance
Be sure to cut out a ventilation hole in the mounting
shelf according to the dimensions in the drawing. See
Figure 02 on page 7.

10baseT LAN
Use an Ethernet cable to connect the MX100 to a
network router. The network connector is located
on the top rear of the MX100 to the left of the
CAUTION label. It is labeled NET.
By default, the MX100 has DHCP set to ON and
will automatically receive an IP address from the
router. This setting can be changed.
HDMI
The MX100 has 4 HDMI Inputs. A high-
performance HDMI cable is recommended to take
advantage of the 18 Gbps speed capabilities of all
5 HDMI ports. The HDMI cables should support
4K@60Hz, and YCbCr 4:2:2 (4:4:4/RGB) as well
as Ethernet and ARC. Cables designed for HDMI
2.0 are ne. Though HDMI is backward compatible,
older cables my have issues with the higher
bandwidth.
Use HDMI OUT/eARC when connecting to an ARC
(Audio Return Channel) enabled television (or any
HDMI capable TV).
ARC can provide two-way communication between
units allowing for volume control and lip-syncing
functions to ensure audio and video are perfectly
matched. This allows for more intelligent operation
between components as well as less cable clutter.
Make sure the ARC is enabled in your TV’s setup
menu.
The MX100 supports eARC. eARC allows for even
higher bandwidth and will allow for higher quality
audio including uncompressed 7.1 surround, Dolby
Atmos and DTS:X.
USB
There is a type-A port on the rear of the MX100
which is labeled USB 5V/1A. The USB port is
used for rmware upgrades and to save and restore
MX100 setup information. The USB port IS NOT
for general USB use or charging devices.
Microphone
The SETUP MIC Input is for connecting
the supplied MX100 Microphone using the
microphone’s attached cable and an 1/8 inch
connector. The microphone is used in the Audyssey
®
calibration for tuning the system to your room. For
instructions see “Audyssey

RS232
The RS232 jack is used to connect the MX100
to automation controller devices with RS232
connectors. To utilize this feature, you will need an
appropriate RS232 Data Cable. The RS232 Data
Cable should be an 1/8 inch (3.5mm) stereo mini
phone plug to a subminiature DB9 connector.

Wired IR Inputs
The IR Input allows an external IR receiver to be
attached to the MX100. The Input is labeled IR IN.
By attaching an IR receiver using a 3.5mm cable
(see Figure 10), the MX100’s Remote Control can
be used in another location without a line-of-sight to
the MX100’s front IR sensor.
IR Data
Control
Ground
N/C
The IR Input is congured for non-McIntosh IR
sensors such as a Xantech Model DL85K Kit.
If using an external IR receiver for the MAIN
ZONE in the same room as the MX100, you may
wish to disable the front IR sensor, which also
controls the MAIN ZONE. This will avoid potential
timing issues of receiving the Remote Control’s
commands from two dierent Inputs. The front IR
can be turned on/o in the GENERAL section of the
SETUP MENU.
Setup>GENERAL>RCLock
To use the front panel to disable or enable the IR
sensor (easier using Setup through a browser):
• Press and hold the LEFT Knob for two
seconds to enter the Setup menu
• Rotate the Left Knob until you see
GENERAL on the display
• Press and release the Left Knob
• Rotate the Left Knob until you see SETUP:
GENERAL RC LOCK on the display
• Press and release the Left Knob
• Rotate the Right Knob to select On or O
RC LOCK ON will disable the front IR sensor so it
will not detect Remote Control input (and possibly
cause interference with a wired IR input). To enable
the IR sensor to detect a Remote Control’s IR data,
set RC LOCK to OFF (the default).
Digital Inputs
There are four digital Inputs in the MX100:
• Two Toslink Optical Inputs
• Two Coaxial Digital Audio Inputs
The two Coaxial Inputs are labeled:
• COAX 1
• COAX 2
The two Optical Inputs are labeled:
• OPT 1
• OPT 2
The default names and assignments can be changed
in setup.
The Optical Inputs require a Digital Optical Audio
Cable Toslink Cable. The Coaxial Inputs use
Digital Audio Coaxial Cables with male RCA type
connectors.
AC Power
This connection is essential. Plug the female end of
the supplied AC Power Cord into the AC connector
located in the rear right corner of the MX100. Plug
the male end of the AC Power Cord into a grounded
and functioning AC outlet.
Balanced Audio Outputs
There are 13 male balanced XLR connections on the
back of the MX100 to accommodate a wide variety
of speaker congurations. Connect balanced XLR
cables to the corresponding powered speakers or
ampliers. Here are the possible connections:
• FR (Front Right)
• FL (Front Left)
• C (Center)
• SR (Surround Right)

HR1 and HL1 should be forward of HR2 and HL2.
The MX100 support of Height speakers is limited to
Top Front, Top Middle and Top Rear locations.
Setting up speakers for a surround setup takes
planning, measuring and installation. Depending
on your level of expertise and available time, you
may wish to employ the services of your McIntosh
dealer for expert setup of your system. Professional
installation of in-ceiling speakers is particularly
important due to gravity and the location above your
head.
The number, types and locations of speakers are
key elements in setting up the system. There is
a multitude of possible congurations, and the
MX100 is very exible in its setup to adapt to many
of these congurations.
Often surround setups are referred to by numbers
for example 7.2.4. The rst number refers to the
number of traditional “oor” speakers (front, center
and surround). The second number is the number
of subwoofers that can be connected, and the third
number refers to the number of in-ceiling or upward
ring speakers in the setup.
The type of speaker (size and location) will be
entered later during Speaker setup. The distance of
the speaker from the listening location is manually
entered in the Speaker setup, or automatically
entered during the Audyssey
®
calibration process.
At this stage, the connection from the MX100 to the
various ampliers and powered speakers should be
made using quality balanced XLR cables.
Power Control (Trigger) Outputs
The MX100 has two Power Control Outputs or
Triggers. Power Control enables power on/o
signals to go to connected components so that other
components can automatically power on (or o) as
called for by the MX100. For example, you may
want a DVD player and a certain monitor to power
on when HDMI 1 Input is selected, or you may want
all components to power o when powering o the
MX100. For Setup instructions see Trigger1 and
Trigger2 on page 21.
Connect components using a 3.5mm stereo mini
plug.

Data Out
The MX100 will convert IR Remote Control data
to share with McIntosh components connected to
the Data Ports. This will allow the operation of
primary functions of a source to be operated with
the MX100’s Remote Control as well as allow
units that are out of range of an IR signal to receive
commands.

Sengs
There are two ways to change the settings of the
MX100.
• Front Panel Method using the Vacuum Flou
rescent Display (VFD) and Left Knob or
Remote Control
• Using a browser on a connected computer
Each method follows the same menu structure. Most
will nd it easier to navigate and enter information on
a computer. If you don’t have a connected computer
or the MX100 is not connected to your network, then
using the Front Panel method can accomplish almost
all the same things using some additional patience.
To use the browser method, you will need the IP
address of the MX100. This can be determined using
the Front Panel Method. After the example below
of determning the MX100’s IP Address, the browser
method will be used for examples to follow in this
manual. The submenus outlined for the browser
menus are the same for the Front Panel Menu.
Clicking the mouse button and selecting with the Left
Knob will traverse the MX100’s Setup in the same
way. To go back in the Front Panel Method, turn
the Left Knob clockwise. The last menu choice is
always “Menu Back”. Choose Menu Back to go to the
previous menu.

Setup from a Browser
Setup is easier from a web browser. Open a browser
window on a computer connected to the same
network as your MX100. Enter the IP address for
the MX100 (see “Determining the IP Address” on
page 13) in the address bar of your browser.
The Setup Menu (see Figure 16) has seven main
submenus.
• Audio
• Video
• Inputs
• Speakers
• Network
• General
• Audyssey
Audio Setup Menu
Setup>Audio
The Audio menu is divided into two main
submenus:
• Audio Adjust
• Audyssey
In the Audio Adjust submenu, the following can be
adjusted:
• Subwoofer Level Adjust
• Bass Sync
• Audio Delay (Lip Sync)
• Volume Scale
• Volume Scale (Linear or dB Level)
• Volume Limit
• Surround Mode Music
• Surround Mode Movie
• Surround Mode Game
Subwoofer Level Adjust
Subwoofer Level Adjust allows for adjusting your
attached Subwoofer to be adjusted from -12dB to +
12dB.
Bass Sync
For contents recorded in multi-channel such as
Blu-ray discs, the recorded Low Frequency Eects
(LFE) may be out of sync and delayed. This
function allows you to correct the delay with an
adjustment of 0 ms to 16 ms.
Audio Delay (Lip Sync)
Audio Delay compensates for incorrect timing
between video and audio. When Auto Lip
Sync is set to On, the timing dierence will be
automatically corrected with compatible TVs.
The Adjust option allows you to manually adjust the
delay correction from the Default of 0 ms up to
500 ms.
Volume Scale
There are two choices for how to display the
Volume. The default is a Volume Scale Linear
which displays the volume on a scale of 0 (mute) to
99. The second option is Volume Scale dB Level.
This will express the volume as decibel (dB) level.
The decibel scale is from -103.0dB (mute) to 18dB.
Note the displayed dB scale increments are not
uniform as they have been designed to give a
meaningful level adjustment depending on the
actual level being listened to.
Volume Scale Linear/dB Level
You can change the current volume level of the
MX100 using the slider. Slide towards the right to
increase. (Left will decrease the volume level.) The
current volume percentage for the linear scale or dB
for the dB scale will appear in the box to the right.
Volume Limit
Volume Limit can protect equipment and/or ears
from unintended extreme volume by setting an
upper threshold for how high the volume level can
be set. Volume Limit can be set to O (the default)
or to one of these three volume limits:
• 60 (-1.5dB)
• 70 (3.5dB)
• 80 (8.5dB)
If Volume Limit is not O, the MX100’s volume
level can not be set above the selected Volume
Limit.
Surround Mode
In the Surround Mode setup, you can assign a
Surround Mode to each of three sound categories:
• Music
• Movie
• Game
These three sound categories can be quickly
assigned to an input using the Trim Menu.
Categories make it easier for someone unfamiliar
with DTS or Dolby to select the proper Surround
Mode by selecting Music, Movie or Game which
can be assigned to any of the following choices in
Setup:
• AUTO (default)
• Dolby Surround
• DTS Neural:X
• Multi-Channel Stereo
• Stereo
Auto
Auto will always send audio to all congured
speakers no matter the input audio stream type.
It will use Dolby Surround to send audio to all
congured speakers if the incoming audio stream is

15
Dolby encoded. It will use DTS Neural:X to send
audio to all congured speakers if a DTS encoded
audio stream comes in. If a 2 channel or multi-
channel PCM stream comes in, it will use Dolby
Surround to send audio to all congured speakers.
Dolby Surround will invoke Dolby’s post
processor to always send audio to every congured
loudspeaker no matter the input stream type.
DTS Neural:X will invoke DTS’ post processor to
always send audio to every congured loudspeaker
no matter the input stream type.
Multi-Channel Stereo will downmix and/or upmix
to send audio to all Left and Right oor speakers
(plus sub if congured) no matter the input stream
type.
Stereo will downmix to send audio to only the Left
and Right front speakers (plus sub if congured) no
matter the input stream type.
Through will neither upmix or downmix. The input
stream will be sent to the congured speakers per
the input le stream with no post processing.
In the Trim Menu (see “The Trim Menu” on page
28), the current input can be assigned to:
• Music
• Movie
• Game
• Auto
• Through
The Surround Mode represented by the Trim
selections Music, Movie and Game must be
assigned in Setup. If no assignment has been made,
the Default for each is Auto.
Audyssey
In the Audio Setup menu, three Audyssey setting
can be adjusted:
• MultEQ
• Dynamic Volume
• Dynamic EQ Oset
MultEQ XT32 optimizes the frequency response
of your speakers. It compensates for both time and
frequency characteristics of the listening area based
on Audyssey
®
Setup.
MultEQ menu options:
• Reference
• Flat
The default setting is Reference. Reference provides
a compensation curve that is optimized for movies
with a slight roll o at the higher frequencies. With
the volume set for 0dB (63%), you will be hearing
the mix at the same level the mixers heard it.
The Flat setting is optimized for small rooms where
your listening position is closer to the speakers.
Keep in mind that many movie soundtracks are
optimized for large theaters. The options in the
Audyssey
®
setup section help maintain the theater
experience in smaller spaces as well as at lower
volumes. The Flat setting utilizes the Audyssey
room correction curves without the additional
compensations for movie mixing.
Dynamic EQ solves the problem of deteriorating
sound quality as volume is decreased by taking
into account human perception and room acoustics.
Dynamic EQ can be turned On and O in the Trim
Menu (see “The Trim Menu” on page 28). If it is
On (the default), the Reference Level Oset option
appears. Audyssey
®
Dynamic EQ
®
is referenced to
the standard lm mix level. It makes adjustments
to maintain the reference response and surround
envelopment when the volume is turned down from
0dB. However, lm reference level is not always
used in music or other non-lm content. Dynamic
EQ Reference Level Oset provides three osets
from the lm level reference (0dB, 10dB, and
15dB) that can be selected when the mix level of the
content is not within the standard.

Dynamic Volume
Dynamic Volume solves the problem of large
variations in volume level between TV, movies and
other content (between quiet passages and loud
passages, etc.) by automatically adjusting to the
user’s preferred volume setting.
The settings available for Dynamic Volume ranging
from least to most adjustment are:
• Light
• Medium
• Heavy
Medium is the default set if Dynamic Volume is
set to On in the Trim Menu (see “The Trim Menu”
on page 28). Dynamic Volume can be turned o
using the Trim menu. The setting chosen in setup for
Dynamic Volume is utilized for all channels when
not turned o. Enabling Dynamic Volume will
also enable Dynamic EQ.
Video Setup Menu
Setup>Video
The Video Setup Menu has breaks into two
submenus:
• HDMI Setup
• On Screen Display
The HDMI Setup Menu has six submenus:
• Pass Through
• CEC
• ARC
• TV Audio Switching
• Power O Control
• Power Saving
The On Screen Display menu has one submenu:
• Volume
Setup>Video>HDMI Setup>Pass Through
Pass Through (written as HDMI PASSTHRU
on the front display) allows an HDMI Input to be
assigned so that when a signal is received by that
HDMI input, while in standby mode, the MX100
will pass the complete signal to the HMDI output
exactly as it was received for video and audio
playback by a connected TV or monitor.
To avoid unexpected results when using the Pass
Through feature, such as your TV powering on
your MX100, CEC should be disabled in setup.

enabled television.
ARC can provide two-way communication between
units allowing for volume control and lip-syncing
functions to ensure audio and video are perfectly
matched. This allows for more intelligent operation
between components as well as less cable clutter.
Make sure the ARC is enabled in your TV’s setup
menu as well as on the MX100.

with another device via an HDMI cable
connection. If you change HDMI Control
settings, reset power to connected devices.
Make sure CEC is enabled on all devices you wish
to utilize CEC.
Setting Values
CEC Off

Notes about ARC and CEC
To use ARC, CEC must also be set to On.
To use CEC and the additional commands of TV
Audio Switching, Power O Control and Power
Saving, CEC must be set to on, so your television
and MX100 can better communicate.
The world of ARC and CEC is not yet perfect. It is
certainly getting better, but not every component in
the world is speaking precisely the same language.

17
There may be circumstances where you may have
better performances by turning these features o.
These features can be enabled or disabled at any
time on the MX100.
Remember to enable CEC on your television if you
want to use CEC with the MX100.
CEC should also be set to O, if you are using
a third-party control system so that CEC does
compete with your external controller.
The ARC feature, when enabled, will work with the
TV Audio input and a television connected to the
HDMI OUT/ARC connection.
TV Audio Switching, Power O Control and
Power Saving are only available options if CEC
is turned On.

Speakers- Setup Menu
The Speakers setup menu is where you tell the
MX100 what the rest of the world looks like. The
basic speaker structure of your system should be
entered in:
• Amp Assign
• Speaker Conguration
• Crossovers
The input of distances of your speakers can be
entered manually. Distances will be provided
automatically when the Audyssey setup program is
run. They can be edited if desired. Audyssey will
run through your speaker conguration. Having
an accurate accounting of your speaker speeds the
Audyssey process by avoiding Audyssey looking for
phantom speakers.
In Amp Assign, you select how to use the
preamplier section of the MX100. In the Amp
Assign section of Setup, you can tell the MX100
what speaker setup scheme you will be using. This
assignment is necessary before running Audyssey
MultEQ calibration.

Speaker Conguraon
Setup>Speakers>Speaker Config
Here is where you tell the MX100 what type of
speakers are connected. The available speaker
categories are based on the settings in Amp Assign
(See page 18).
Speakers are dened as Large or Small. A Large
Speaker is a full-range speaker. (Technically, a
speaker able to reproduce bass frequencies down to
35Hz within -3dB of the midrange frequencies.) If it
is not Large, then it is Small.
Set each speaker catagory to Large or Small. For a
system with a Subwoofer(s), choose the number of
subwoofers (1 or 2).

Top Rea r Large / Small
Top Middle Large / Small
Crossovers
Setup>Speakers>Crossovers
Sound below the crossover frequency is cut o from
the Output to “Small” speakers and is outputted to
the subwoofer or front speakers.
The default crossover frequency is “80Hz”, which
will work best with the widest variety of speakers.
We recommend setting to a higher frequency
when small speakers are used. For example, set to
“250Hz” when the frequency range of the speakers
is 250Hz to 20kHz.
Sound below the crossover frequency is cut o from
the Output to “Small” speakers and is outputted to
the subwoofer or front speakers.
You can choose Individual or All. The Individual
option will allow each available speaker’s crossover
frequency to be set individually. The All option will
globally set the Crossover Frequency to the chosen
value. Available values are:
40 Hz / 60 Hz / 80 Hz / 90 Hz / 100 Hz /
110Hz / 120 Hz / 150 Hz / 200 Hz / 250 Hz
Bass Type
Setup>Speakers>Bass Type
The Subwoofer Mode can be set for:
• LFE (Low Frequency Eects) which would
provide, to the subwoofer(s), the LFE channel
plus the low frequency output below the set
crossover frequency of speakers set to small
(see “Speaker Conguration” on page 19)
• LFE+Main which would include the LFE
channel as well as the low frequency output,
below the set crossover frequency, of the
Main channel
Figure 18– Dolby Enabled speakers

The Bass Low Pass Filter (LPF) sets an upper limit
for frequencies that are sent to the Subwoofers when
LFE+Main is selected. The options are:
80 Hz / 90 Hz / 100 Hz / 110 Hz / 120 Hz /
150 Hz / 200 Hz / 250 Hz
Frequencies above the choosen option will not be
sent to the Subwoofer. The LPF setting does not
apply to content sent from the LFE channel to the
subwoofers.
Speaker Distances
Setup>Speakers>Distances
In this section, the distances of your speakers from
the main listening position should be entered. This
will aid in perfecting 3D imaging.
For each speaker listed in the pull-down Distances
menu, enter the distance from the main listening
position to the speaker in meters.
To convert feet to meters, multiply the number of
feet by 0.3048.
The value can be accurate up to a tenth of a meter.
The Audyssey program will provide more exacting
information. The information entered here provides
a baseline to compare the Audyssey ndings.
For Dolby Enabled speakers, enter the distance to
the speaker. Do not calculate the angled path that
the reected sound will travel. Audyssey will handle
this.
Test Tones & Levels
Setup>Speakers>Test Tones & Levels
The Test Tones and Levels submenu provides the
ability to manually set relative levels for all speaker
types, and may be used to conrm proper wiring.
This does not need to be set if using Audyssey
calibration.
When Test Tone is set to On, a tone will play
through the Speaker type selected in the Levels
dropdown box. Using a sound meter or your ears,
you can set the relative level from -10dB to +10dB.
The default is 0dB.
Audyssey will automatically set levels and will
over-write osets set previously. Likewise,
manually setting Test Tones will replace Audyssey
settings.
Network Setup Menu
Setup>Network
The Network Setup menu has four sections:
• Network Information
• Network Control
• Friendly Name
• Network Settings
Network Information displays the IP Address and
the MAC address of the MX100. For instructions on
determining the IP Address using the front panel see
“Determining the IP Address” on page 13.
Network Control has two settings: On or O. The
default is O. When Network Control is enabled
(On), a control system such as one using RS232
commands over IP can awaken the MX100 from
a sleep state. When Network Control is o, the
MX100 will enter standby mode when powered o.
The monitoring of network trac with Network
Control On uses slightly more power when the
MX100 is in sleep mode.
Friendly Name provides a more individual way
of identifying your MX100 on the network with
devices that recognize Friendly Names.
The default Friendly Name of “MX100” can be
changed by selecting an alternative name from the
Preset Name dropdown list. To create your own
name for the MX100, choose “Custom” from the
Preset Name dropdown box and then type the new
name in the Friendly Name box. Custom names can
only be entered from the Browser interface. Preset
names can be chosen using the front panel interface.
Network Settings allows you manually entering
network information. You may do this if you want to
have a static IP Address for the MX100. The default
is for DHCP is On. With DHCP on, all the network
information will be assigned automatically from
your router.
To manually enter Network Settings, select “O”
for DHCP. This will allow you to enter settings for:
• IP address
• Gateway (typically the IP address of your
router)
• Subnet Mask (Typically 255.255.255.0)
• DNS address (typically the IP address of your
router)
When you have completed making Network
Settings changes, select the “Apply All Settings”
button to save your changes.
General Setup Menu
Setup>General
The General Menu has Six submenus:
• Firmware Info
• Save and Load
• Trigger1
• Trigger2
• RCLock
• Auto O
Factory Reset
Factory reset and the ability to save congurations
are part of the General Setup Menu.

21
Firmware Info displays the installed version of
the MX100’s rmware. Firmware is software that
controls hardware as a low level. Occasionally,
new versions of rmware may be issued to address
particular issues. If you are not experiencing any
issues, there is no need to upgrade your MX100
rmware. If the need should arise, your McIntosh
dealer has access to the latest rmware.
Firmware Update is used to install new rmware.
The new rmware should be unzipped on the root
directory of a properly formatted USB drive (FAT
or Fat32). The USB drive should be inserted into
the USB port on the rear of the MX100. Selecting
the Update Now button will begin the process.
It is highly recommended that your McIntosh
dealer perform the update process since failure
to properly install the rmware can leave the
MX100 in an unusable state.
Factory Reset will restore the MX100’s defaults.
Any changes made will be lost. Congurations
can be saved and restored in the “Save and Load”
section of the General Setup menu.
MX100’s Audyssey information is saved with
Conguration backups. Audyssey should be re-run
anytime a signicant change is made in your system
or its environment.
To Save the Conguration using the Web Page/
Browser interface, select the Save Conguration
button. Choose the destination to store the le. A le
named “MX100_cong.cfgs” will be created. If you
choose, you can rename this le and save dierent
setup congurations. Note that congurations
created using the Web Page/Browser interface
must be restored using this interface and CAN
NOT be restored using the MX100’s Front Panel
interface or MX100’s USB port.
If you wish to store to a USB drive in the MX100’s
USB port, you must use the Front Panel interface.
To use the Front Panel interface to Save the
Conguration:
• Insert a USB Drive in the MX100 USB port
• Go to the Save and Load submenu, and select
Save
Two les are created when using the Front Panel to
save to a USB drive in the rear of the MX100:
• AUDSY.MEQ which contains the Audyssey
lter information
• MX100.CFG which contains the custom
MX100 settings
To load a saved Conguration, select the Load
Conguration button. Choose saved conguration
le from its location either from a folder on
your computer or a USB drive inserted into the
computer’s USB port. Conguration les by default
are named “MX100_cong.cfgs”. Choose this
le or a le you have custom named. Select open.
The interface will say “Upload Complete” and the
MX100 will power cycle and the new settings will
be loaded.
If you are using the Front Panel to Load a
Conguration:
Insert the USB Drive with the conguration le
stored in the root directory in the MX100 USB port
Go to the Save and Load submenu and select Load.
Progress will be displayed for loading the two
conguration les. The MX100 will power cycle
when complete. The restored settings will be in
eect.
Trigger1 and Trigger2 can each be set to power
on/o components connected via a Power Control
Cable (see “Power Control (Trigger) Outputs” on
page 12).
Each Trigger can be set to:
• Independent allows each individual Input to
be set to On or O. When an Input that is set
to On is selected, connected components will
receive a Power Control signal to Power On
until the selected Input is changed (to an Input
that is set to O) or the MX100 is powered
O.
• All On sets the Power Control setting of all
Inputs to On. With this selection, any Input
will generate a Power Control signal to be
sent for that Trigger. All On is a quick way to
change all the Inputs to On. You can switch to
Independent to set any individual Input to O.
• All O sets the Power Control setting of all
Inputs to O. With this selection, no Input
will generate an On signal for the Trigger. All
O is a quick way to change all the Inputs to
O. You can switch to Independent to set any
individual Input to On.
When Independent is selected, you can select On or
O for these Inputs:
• HDMI1
• HDMI2
• HDMI3
• HDMI4
• HDMITV
• Optical1
• Optical2
• Coaxial1
• Coaxial2
If set to Independent, Trigger2 has an additional
Input option:
• ARC

22
RCLock when enabled (On) will prevent the front
IR sensor from receiving IR commands from a
Remote Control. The default for RCLock is O. For
more information regarding IR Inputs, see “Wired
IR Inputs” on page 11.
Auto O, when Enabled, the MX100 will power o
after 30 minutes of no input. If you pause a movie
for more than 30 minutes and you do not want to
nd the MX100 powered o, you would want to
Disable Auto O.

Audyssey
®
Audyssey is an intelligent system which will ne-
tune your system to properly interact with the room’s
acoustics through precise calibration. This will get
the highest possible performance from your complete
system providing a tighter and more detailed sound
with increased imaging.
Audyssey Setup uses multiple measurement locations
in the listening room to achieve the best possible
acoustical results. The Focus Position or Main
Listening Position is typically where one would be
during serious viewing/listening.

Before proceeding with Audyssey Auto Setup, it
is very important to rst go into the Amp Assign
submenu of Setup to establish the correct settings for
your specic Loudspeaker complement and location
in the Home Theater Room. The Audyssey submenu
has a button for the Amp Assign submenu so you
can conrm your settings. This will not only assure
the best acoustic performance using Audyssey Room
Equalization Correction, but it will also assure the
best sonic performance using the latest in surround
sound technology built into the MX100. The acoustic
characteristics of the connected speakers and listening
room are measured and the optimum settings are made
automatically.
Audyssey Procedure Overview
• Complete Amp Assign (see “Amp Assign” on
page 18)
• Connect assembled Microphone (see Figure
21)
• Place Microphone in the Focus Position (see
Figure 19)
• Begin Test (adjust volume)
• Move Microphone to next position
• Continue, repeat with new positions
• When complete, select Complete
Audyssey Setup
Assemble the supplied setup microphone and stand
(see Figure 21) then place it in the Main Listening
Position or Focus Position. (See Figure 19)
For best results:
• Make the room as quiet as possible. Background
noise can disrupt the room measurements. Close
windows and turn o the power on electronic
devices (radios, air conditioners, uorescent
lights, etc.). The measurements could be
aected by the sounds emitted by such devices
• During the measurement process, place cell
phones outside the listening room. Cell phone
signals could disrupt the measurements
• Do not stand between the speakers and Sound
calibration microphone or allow obstacles in the
path while the measurements are being made.
Also, install the Sound calibration microphone

at least 20 inches (50cm) away from the
wall. Failure to do so will result in inaccurate
readings
• During the measurement process, audible
test tones will come from the speakers and
subwoofer(s), but this is part of normal
operation. If there is background noise in the
room, these test signals will increase in volume
• Operating VOLUME on the Remote Control
unit or VOLUME on the main unit during the
measurements will cancel the measurements
Begin Audyssey
With your speakers properly dened in Amp
Assign and the Microphone set up and in the Focus
position:
• Go to the Audyssey menu in the MX100
Browser interface Setup>Audyssey. Select
“Next” (see Figure 23)
• Set the MX100 volume for approximately
50% (-6.5 dB). This setting can be adjusted
for your circumstances upon subsequent tests.
You can always abort a test and begin again.
If the volume is set too low, your speakers
will show as Not Detected after the test. If you
heard a tone from the speakers during the test
but the speakers were not detected, turn the
Right (VOLUME) Knob up (clockwise) and
repeat the test using the Repeat Test button.
• Select “Begin Test” (see Figure 24)
• A test tone will be sent to all channels, one
at a time to identify the channels making up
your system.
• When the detected speakers are displayed,
select "Next Step". This will start the
Measurement Process. A special audio test
signal will be sent to all previously detected
channels, one at a time
• Leave the Microphone in the Focus Position
for Calibration Position 0 (---). Select
“Continue” (see Figure 25)
• After the series of tones end and the
word “calibrating” disappears, move the
Microphone to a new Calibration position no
more than two feet (60cm) from the previous
position. Select “Continue”
• Repeat the above step until completing
between three and a maximum of six
Calibration positions. Press “Complete” when
you are done testing
• On the next screen select “Continue” to
analyze the data (see Figure 26)
