4. Half Rack Width Amplier Installation
PowerZone™ Connect 122/122D, 252, 254 and 504/504D
Note: The rack mounting and desk/wall mounting components
described and illustrated in Sections 4.1 to 4.3 are not supplied with
PowerZone™ Connect ampliers but are available to purchase as
accessories. Contact your amplier re-seller for more information.
4.1 PowerZone™ Connect Mounting
PowerZone™ Connect half rack width ampliers are shipped
without rack mount hardware attached but can be congured
for rack installation using one standard rack ‘ear’ and one
half-rack extension piece as illustrated in Diagram 4A. The
installation and equipment rack should be congured to
provide appropriate ventilation airow space around the sides
and rear of the amplier. Ventilation airow space of at least
25 mm (1 in) should be maintained along at least one side of
the amplier at all times. Ventilation apertures are also located
on the rear panel of the amplier and must not be obstructed.
It is important to retain at least 80 mm (3.1 in) free space for
airow behind the amplier rear panel.
In addition to rack mount ears, rack mount rear support
hardware is optionally available and can be attached to the
amplier. Rear support hardware may be appropriate if
the amplier is to be used in a mobile rack or potentially be
subject to signicant movement. Diagram 4B illustrates the
use of rack mount rear support hardware.

Conguration
6. Conguration
Before making input, output and GPIO connections, an
initial PowerZone™ Connect amplier conguration
should be established. It is particularly important that
the amplier output format is congured appropriately
for the speakers that are to be connected.
Conguration requires that PowerZone™ Connect
ampliers are connected to mains power and network
services. These connections are described in the
following two sections.
6.1 Mains Power Connection
PowerZone™ Connect ampliers incorporate a power factor
corrected power supply and can be used with mains input
voltage from 100 V AC to 240 V AC, 50 / 60 Hz. Use the mains
cable supplied with the amplier and connect it to a switched
mains supply.
PowerZone™ Connect ampliers have no mains power switch
and are operational as soon as mains power is connected.
6.2 Network Services
PowerZone™ Connect ampliers are congured via a
web page interface called PowerZone™ Control. Before
the conguration menus can be accessed, PowerZone™
Connect ampliers must be connected to the same TCP/
IP network as the computer or mobile device that is to
be used for conguration access.
6.2.1 Wired (Ethernet) Network Connection
To connect a PowerZone™ Connect amplier to a TCP/IP
network using a wired connection (Ethernet) follow the steps
below.
1. Use an Ethernet cable to connect the PowerZone™ Connect
amplier rear panel Network Control socket (upper socket) to
a free socket on a network router or switch, or directly to an
Ethernet equipped laptop or desktop computer.
2. Connect the PowerZone™ Connect amplier to mains
power using the supplied mains cable. Wait for the front panel
Network indicator to illuminate green to indicate that the
amplier has network connectivity.
3. The PowerZone™ Connect amplier default LAN IP address
is 192.168.64.100. Congure the laptop or desktop computer
for a xed IP address in the same IP range; eg. 192.168.64.10,
with Subnet mask of 255.255.255.0 (or prex 24) and set the
Gateway to 192.168.64.1.
4. Open a laptop or desktop web browser and enter the
address http://192.168.64.100. The PowerZone™ Control Web
App interface will open to enable amplier conguration as
required.
Note: PowerZone™ Connect ampliers can be congured
to use DHCP for network connection if required. However, if a
PowerZone™ Connect amplier using DHCP is power cycled, it
is possible that the TCP/IP network router will assign it a different
IP address, leaving its conguration page inaccessible via the
previous address. If this occurs, a network scanning app can be used
to identify the new IP address. DHCP and Fixed IP address option
settings can be found in the Settings Tab menu described in Section
6.3.
Note: The second network socket present on the amplier rear panel
is intended for Audinate Dante
®
AoIP network connection only. It
cannot be used for PowerZone™ Connect control connection.
6.2.2 Wireless (WiFi) Network Connection
To connect a PowerZone™ Connect amplier to a TCP/IP
network using a wireless connection (WiFi) follow the steps
below.
1. With the PowerZone™ Connect amplier connected
to mains power, wait for the front panel WiFi indicator to
illuminate green.
2. Use a mobile, laptop or desktop device to search for available
WiFi networks. Connect to, PowerZone™ Connect (product
serial number)’ using the password, ‘password’. The amplier
serial number can be found on its rear panel.
3. Open a computer or mobile device web browser and enter
the IP address: 192.168.4.1. The PowerZone™ Connect Control
Web App interface will open to enable amplier conguration
as required.
4. Select the Web App Settings Tab followed by WiFi > WiFi
Mode > Client to congure the amplier to connect to the
required WiFI network. The WiFi network name and password
will be required.
It is strongly recommended that the PowerZone™ Connect
amplier Access Point WiFi password is changed following
initial wireless connection.

Conguration
6.3.1 Input Tab
The Input Tab provides the following conguration parameters
for each amplier input channel:
• Input name
• Mono/Stereo selection
• Input sensitivity
• High-pass lter
• Gain trim
• Five band equalisation
The Input Tab also enables input signals to be mixed and routed
to specic amplier zones. The mix function enables any
amplier input, including stereo or split mono S/PDIF inputs,
to be grouped with any other input or inputs to create multiple
predened mixes.
Note: The number of individual mixes possible is equal to the
number of amplier analogue outputs (two outputs enables two
mixes, four outputs enables four mixes, eight outputs enables eight
mixes).
Note: Mix inputs are muted by default with their level adjustment
sliders set to zero.
Mix operations take place following high-pass lter, input
equalisation and mono/stereo selection.

or Windows application. If no inputs are displayed they must rst be
enabled in Dante
®
Controller.
6.3.2 Zone Tab
The Zone Tab enables installation zones to be dened and
named, and provides access to further sub-menus. Zones
might be bar or restaurant areas for example, or different
rooms in a home. For all Zone Tab menus, the installation zone
under conguration is selected by highlighting one of the zone
identiers (A to H depending on amplier output count) at the
top of the display. Diagram 6F and 6G illustrates the Zone Tab
and Source menu displays.
• The Source menu enables inputs to be assigned to zones
and Input Priority or Input Ducking to be congured. The
Input Priority function enables up to three alternative
inputs to the Primary Input on each of the zones. This
provides the possibility to prioritize, replace and mute the
input(s) routed to the zone when the alternative input(s)

exceed(s) a preset level. The Primary Input is the main
input, such as background music played in a shopping
centre. 1. Priority Low, for example commercials, takes
priority over the Primary Input. 2. Priority Mid, e.g.
paging, takes priority over both background music and
commercials. 3. Priority High, such as an emergency alarm,
takes priority over and mutes all other inputs.
The Input Ducking function enables an alternative input,
Ducking Low, to replace and attenuate the Primary Input
routed to the zone under conguration when the alternative
input exceeds a preset level.
Note: The Priority Low parameters can be either set to default
values or to its Threshold, Attack, Hold and Release values as
required (Manual). The Priority Mid and Priority High parameters
can be either set to default values or to their Threshold and Hold
values as required. All Input Priorities can also be set to ignore the
volume level set for the specied zone (Override Zone Volume).
The Ducking Low parameters can be either set to default values or
its Threshold, Depth, Attack, Hold and Release values as required.
• The Volume menu allows minimum and maximum zone
volume limits to be set, and enables external GPIO volume
control to be applied to individual zones. The GPIO
conguration menu can be found under the Settings Tab,
and notes on connecting an external volume control via the
Diagram 6G
Zone Source menu display
GPIO interface can be found in Section 6.5 of this manual.
Note: If an amplier is controlled via a third-party control system
API, volume level limits set via the Input Tab will not apply.
• The Restrictions menu enables zone inputs or input mixes
to be restricted from routing to particular zones.
Note: Routing restrictions cannot be applied to priority zone inputs.
Note: If an amplier is controlled via a third-party control system
API, input routing restrictions set via the Input Tab will not apply.
• The Compressor option enables default or custom signal
compression to be applied to individual zones.
Note: Compression can be useful to reduce the volume difference
between loud and quiet audio material. The lower the compression
threshold is set, the more the difference between loud and soft will
be reduced. The overall zone volume may need to be increased
when compression is used. The default compression parameters are
appropriate for most installations.

Speaker Preset menus. Diagram 6H illustrates the Output Tab
display.
For all Output Tab menus, the amplier output under
conguration is selected by highlighting one of the output
identiers at the top of the display.
Note: The number of individual outputs available for conguration
will depend on the PowerZone™ Connect amplier model and the
input, zone and output mode conguration. The diagrams following
illustrate a four output amplier.
• The Routing menu enables zones to be assigned to amplier
outputs.
Note: Routing for zones specied as stereo will automatically offer
three output options: left channel, right channel or summed mono.
The summed mono signal can potentially be used to drive a mono
subwoofer or a 70/100V mono speaker line.
• The Delay menu enables delay to be applied to individual
amplier outputs.
• The Equalizer menu enables parametric equalization to be
applied to individual amplier outputs. Equalizer settings
congured for one amplier output can be copied and
applied to other outputs.
• The Speaker Preset menu enables a set of speaker
parameters to be adjusted, and preset congurations to be
created, exported, imported or cleared.
Speaker Presets can be simply applied to the selected
amplier output or imported, chosen from a library,
exported or cleared. The preset congurations can include
any or all of the parameters described in Section 6.3.4
and can be locked to prevent inadvertent modication.
Diagrams 6I to 6L illustrate the application of speaker
presets.

• The Limiter preset menu enables signal limiting to be
engaged or bypassed on individual amplier outputs. Clip
limiting, Peak limiting and RMS limiting can be individually
or collectively engaged. The Clip limiting function offers
Fast and Normal response time options. The Peak limiting
function can be set to either Automatic or Manual
parameter values. The RMS Limiter has default parameter
values that can be adjusted but has no automatic option.
Note: In automatic mode, the peak limiter parameters adjust
automatically in response to Crossover & Gain high-pass lter
settings.
• The Output Mode preset menu enables individual
amplier outputs to be switched off or congured for Lo-Z
or Hi-Z modes. In Hi-Z modes, a high-pass lter can also
be congured and applied to the output. The number of
outputs available will depend on the amplier model, input
setup and zone setup. For example, a two output amplier
will have two outputs available if Lo-Z mode is selected but
only one output available if Hi-Z mode is selected.
Note: Use of a high-pass lter with Hi-Z mode loudspeakers is useful
to avoid the possibility of distortion caused by low frequency line
transformer saturation. Begin with the default lter setting of 70Hz.
If low frequency distortion is still audible, increase the frequency
setting one step at a time until the distortion is no longer audible.
6.3.5 Settings Tab
The Settings Tab enables miscellaneous amplier settings to be
congured and installation data to be recorded. The Settings
Tab provides access to further sub-menus. Diagram 6M
illustrates the Settings Tab.
• The System Information menu provides text elds for the
recording of installation data.
• The Device menu records amplier specic information
such as the model number and rmware version. A rmware
update routine and identier button can also be found
under the Device menu.
• The External Devices menu enables control panels to be
paired with an amplier and congured. Depending on

product, setup and conguration, each device can remotely
control one single or multiple amplier zones. Diagram 6N
illustrates the External Devices display.
• The Backup & Restore menu enables amplier
conguration data to be downloaded to an external archive,
and enables previously saved conguration les to be
uploaded and adopted by the currently connected amplier.
• The Speaker Library menu enables management of speaker
preset libraries. Existing libraries of speaker preset les
(.zcl) can be created or imported, and existing libraries
edited or fully deleted. Diagram 6O illustrates the creation
and management of speaker preset libraries.
• The Security menu enables a password to be set in order
to protect against unauthorised access to the amplier
Control Web App. Password protection is particularly
important when an amplier is connected to a wired
network as the a WiFi password is no longer required to
gain access to Control Web App.
Note: It is recommended that a Control Web App password is
different from that required to gain access to the amplier via WiFi.
• The Power Management menu enables various automatic
switch-on options to be engaged. The Power Management
menu also offers timed Standby and Mute functions.
Note: In Eco mode the network is switched off during standby. When
the amplier has Dante
®
enabled use the Audio (Digital) or Network
Only settings.
• The Output Routing menu enables specied inputs or zones
to be routed to the amplier S/PDIF outputs. The output
level can also be adjusted.
Any zone or input can be routed to either digital output,
including inputs not actively assigned to a zone. Primary
or priority input status is immaterial. The specied input is
always routed to the specied output to be available for use
by downstream devices.
Note: When a zone is selected for the digital S/PDIF (or Dante
®
)
output - the output signal is variable. However, when an input signal
is routed out an S/PDIF (or Dante
®
) output, the signal will be xed.
Note: The digital output function is especially useful when ampliers
are to be daisy chained and a specic input; a central paging mic, for
example, is required to be routed to multiple ampliers.
• The Dante® menu enables identication of Dante® capable
devices present on the AoIP network. Dante® devices must
be appropriately enabled and congured using Dante®
Controller. Use Dante
®
Controller to activate AES67 mode
if required.
• The GPIO menu enables conguration of the multi-purpose
GPIO interface pins. A description of the individual settings
is detailed in PowerZone™ Control.
• The LAN menu enables conguration and reset of the wired
network options and parameters.
• The WiFi menu enables conguration and reset of the
wireless network options and parameters.
6.4 Setup and Signal Routing
Thanks to their network based conguration features,
PowerZone™ Connect ampliers offer considerable
versatility in terms of sources, signal routing, installation zones
and output modes. Inputs can be freely assigned to installation
zones, and those zones assigned freely to the available amplier
outputs in either Lo-Z or Hi-Z modes.
This versatility enables, for example, one amplier
simultaneously to drive both Lo-Z and Hi-Z speakers, or for
different inputs to be routed to different output zones.
The following paragraphs describe and illustrate the
recommended procedure for conguring input, zone and
output routing. A general signal ow schematic is also
illustrated in Diagram 6P.

Conguration
6.4.1 Input Setup
Open the conguration Dashboard and select the Input Tab.
The Input Tab is shown in Diagram 6B.
• To edit default input names simply select and type in the
Input Name eld.
• Dene a mono or stereo input by selecting the appropriate
option. Dening a stereo input will reduce the total number
of discrete inputs available.
• Select an input sensitivity option from the drop-down
menu: +14dB, +4dB, -10dB and ‘microphone’ options
are available. Generally, the +14dB or +4dB options are
appropriate for ‘professional audio’ source hardware
with balanced outputs, while the -10dB option is more
appropriate for ‘consumer audio’ source hardware with
unbalanced outputs. The ‘microphone’ option provides the
signicantly greater sensitivity required for microphones.
Note: Only dynamic microphones are suitable for connection.
Phantom power for condenser microphones is not provided.
• If necessary, adjust the input gain using the slider or up/
down icons. Gain adjustment is intended to be used for ne
output level adjustment following initial use. If necessary,
adjust the input EQ using the 5 band equalizer.
6.4.2 Zone Setup & Routing
Open the conguration Dashboard and select the Zone Tab.
The Zone Tab is shown in Diagram 6F.
• Select the zone to be congured. The number of zones
available and their channel format (stereo or mono) will
depend on the amplier model, input setup and output
mode (Lo-Z or Hi-Z). For example, a two output amplier
can have the following zone congurations:
• 1 x stereo Lo-Z zone
• 2 x mono Lo-Z zones
• 1 x mono Hi-Z
• A four output amplier can have the following zones
congured:
• 2 x stereo Lo-Z zones
• 4 x mono Lo-Z zones
• 2 x mono Hi-Z
• 1 x mono Hi-Z + 1 x stereo Lo-Z zone
• 1 x mono Hi-Z + 2 x mono Lo-Z zones
• An eight output amplier can have the following zones
congured:
• 4 x stereo Lo-Z zones
• 8 x mono Lo-Z zones
• 4 x mono Hi-Z or zones
• 2 x mono Hi-Z or + 2 x stereo Lo-Z zone
• 2 x mono Hi-Z or + 4 x mono Lo-Z zones
Note: When congured in Hi-Z mode PowerZone™ Connect
ampliers operate in ‘bridged’ format where the output of two
channels is combined. This means that the number of output
channels available in Hi-Z mode is half that available in Lo-Z mode .
BTL mode is only allowed for speakers with an impedance of 8
Ohm or higher.
Note: Mono signals might be mono at source, created though
combining the left and right channels of a stereo signal (summed
mono) or treating the left and right channels of a stereo signal
independently (split mono).
• Name zones by typing in the Zone Name eld.
• Adjust the zone volume if required by using the slider.
• Dene a mono or stereo zone by selecting the appropriate
option. Dening a stereo zone will reduce the total number
of further zones available.
• Specify an input for the zone by selecting from the drop-
down menu. Selecting a stereo input for a mono zone will
automatically sum the stereo channels to mono.

6.5 GPIO Setup and Connection
PowerZone™ Connect ampliers provide a GPIO socket that
enables remote control of volume, standby, mute and trigger
functions. The GPIO connector pin functions are described
in the GPIO Settings menu illustrated in Diagram 6Q. The
connection of GPIO based remote volume control and
standby/mute are illustrated in Diagram 6R and Diagram 6S
respectively.
Note: The GPIO connector must not be used for any
unintended purpose. Amplier damage may result from
incorrect use of GPIO.
Note: Shielded cable must be used when connecting standby
switches and potentiometers via GPIO.
Note: GPIO Pin 8 has a low output impedance and is able to
supply a maximum current of 10mA.
Note: GPIO Pin 1 and Pin 3 both offer ground connections:
Pin 1 is connected directly to the amplier chassis.
Pin 3 is connected to the chassis via a 220 Ohm resistor. The ‘soft
ground’ connection of Pin 3 is potentially useful for managing
ground loops that may cause audible hum.

7. Connections
PowerZone™ Connect amplier rear panel connections
are illustrated in Diagrams 7A and 7B.
7.1 Mains Power Connection
PowerZone™ Connect ampliers incorporate a power factor
corrected universal power supply and can be used with mains
input voltage from 100V AC to 240V AC, 50/60Hz. Use the
mains cable supplied with the amplier.
PowerZone™ Connect ampliers have no mains power switch
and are operational as soon as mains power is connected.
Ensure that all signal, GPIO and output connections are made
before connecting the amplier to mains power.
7.2 Input Connection
All PowerZone™ Connect amplier models provide four
balanced or unbalanced analog audio inputs and a stereo S/
PDIF digital audio input. Any input channel can be routed to any
output channel. Input routing options can be congured via the
amplier network interface. See Section 6 of this manual.
Analog Inputs
PowerZone™ Connect analog inputs are of line level format
with a default input sensitivity of +4dBu (full output voltage
swing/sensitivity) in all output modes. Input signal levels up to
+24dBu can be handled without input clipping. Input sensitiv-
ity options can be set via the amplier network interface. See
Section 6 of this manual.
Balanced input connections to the ampliers are made via male
‘Euro Block’ connectors. Connecting cables to the supplied
female input connectors is illustrated in Diagram 7C.
Unbalanced input connections to the ampliers are made via
RCA phono sockets connected in parallel with the balanced
inputs.
Diagram 7A
Half rack width PowerZone™ Connect amplier rear panel
connections.
Note: Two output amplier model connection sockets differ only in
the deletion of channel 3 and channel 4 output connectors.
Digital Outputs
PowerZone™ Connects S/PDIF stereo digital audio output
connections are made via a single RCA Phono socket. The S/
PDIF output signal can be routed from any input or zone and is
intended to be used for daisy-chaining PowerZone™ Connect
ampliers.
Note: See the Output Routing paragraphs of Section 6.3.3 for more
information on Digital Output conguration.
Note: 75Ω RCA Phono cables specically intended for digital audio
should always be used for S/PDIF connections. Standard Phono
cables can be used but may not result in optimal performance.
Note: The S/PDIF output level is by default set at -10dB to reduce
the possibility of downstream input clipping.
7.3 Output Connections
Output connections from the ampliers are achieved via male
‘Euro Block’ connectors. Ensure that speaker connection
polarity is correct throughout the installation:
In the case of Lo-Z speaker connections, positive (+) amplier
terminals should always be connected to positive speaker
terminals and negative (–) amplier terminals always connected
to negative speaker terminals.
In the case of Hi-Z speaker connections, the two speaker cable
conductors should be connected between the positive (+)
terminal of Output 1 and the negative terminal (-) of Output 2,
and likewise for and additional Hi-Z outputs.
Output mode options (Lo-Z or Hi-Z) can be congured via the
amplier network interface. See Section 6 of this manual.
Connecting cables to the supplied female output connector is
illustrated in Diagram 7D.

Operation
8. Operation
Once all connections have been made and conguration
options selected, PowerZone™ Connect ampliers
are ready for use. If an input signal above -60dB is
present on any input, the front panel Input and Standby
indicators will illuminate green to indicate normal
amplier operation. Audio will be heard from any
connected speakers.
Note: PowerZone™ Connect ampliers will not switch on from
Standby Mode unless an input signal is present, a network ‘ON’
command is received, or an external standby switch (or 12V trigger)
is operated. Standby behaviour can be congured via the Power
Management menu of the Settings Tab.
Amplier outputs will mute if no input signal is present for 5
minutes, and the amplier will switch automatically to Standby
Mode if no signal is present on any input for more than 15
minutes. Alternative standby and mute delay times can selected
via the Settings Tab. Amplier cooling fan speed is temperature
controlled. The fan will switch off when the amplier enters
standby mode.
8.1 Front Panel Indicators
PowerZone™ Connect amplier front panel indicators illumi-
nate to indicate the following operational states:
Status: Off – Mains power disconnected.
Green – Amplier operational.
Pulse Green – Standby Mode.
Amber – GPIO triggered Standby Mode
Input: Off – No input signal present.
Green – Signal present on one or more inputs.
Amber – Signal limiting/clipping on one or more
inputs.
Output: Off – No output signal present.
Green – Signal present on one or more outputs.
Amber – Signal limiting/clipping on one or more
outputs.
Red – One or more channel pair is in
overload/protection mode.
Network: Off – No Ethernet network detected.
Green – Ethernet network detected.
WiFi: Off – WiFi disabled.
Green – WiFi enabled.
8.2 Automatic Power Sharing
PowerZone™ Connect ampliers incorporate a power sharing
feature that automatically shares the total power available
from the amplier’s internal power supply across each pair of
output channels. If one channel temporarily demands more
than the amplier’s continuous power rating while other
channel is demanding less, the excess power available from the
internal power supply is automatically made available to the
over-power channel. Power sharing optimises the amplier’s
ability to deliver maximum power into dynamic loudspeaker
loads when playing music programme material.
8.3 Default Reset
PowerZone™ Connect ampliers can be returned to their
default settings via either the Control Web App Settings Tab or
the hardware reset pinhole button. The reset pinhole button is
located on the underside panel of the amplier.
To reset the amplier using the pinhole button, follow the steps
below:
• Disconnect the amplier from mains power.
• Use an appropriate tool to press and hold the reset
pinhole button while simultaneously reconnecting mains
power.
• Continue to hold the reset pinhole button for 3 seconds as
the amplier restarts.
The amplier will restart with all settings at their default state.
Any previously congured settings will be deleted.
