5.4 Setup and Signal Routing
PowerZone Connect PRO amplifiers provide flexible
signal routing for a wide range of installations. Inputs
can be assigned to zones, and zones can then be
routed to amplifier outputs. This allows dierent source
signals to be routed to dierent areas of an installation,
or the same source signal to be routed to multiple
zones.
Signal routing is configured in three main steps:
1. Configure the required input sources in the Input tab.
2. Configure zones and assign sources in the Zone tab.
3. Assign zones to amplifier outputs in the Output tab.
A general signal flow schematic is illustrated in
Diagram 5P.
5.4.1 Input Setup
Open the Input tab to configure the required input
sources.
For each input, confirm or configure the input name,
mono/stereo setting, input sensitivity, high-pass filter,
gain/trim, and input EQ as required.
Select an input sensitivity setting appropriate for the
connected source equipment. Generally, +4 dBu or
+14 dBu are appropriate for professional audio source
equipment, while -10 dBV is appropriate for consumer
audio source equipment. The MIC setting provides
the higher sensitivity required for microphone-level
sources.
Note: Only dynamic microphones are suitable for
connection. Phantom power for condenser microphones
is not provided.
Adjust input gain only as required after selecting
the appropriate input sensitivity. If the input meter
indicates clipping or limiting, reduce the input gain or
select a less sensitive input setting.
Lastly, if necessary, adjust the input EQ using the
5-band equalizer.

Configuration
5.4.2 Zone Setup & Routing
Open the Zone tab to configure zones and assign
sources.
Select the zone to be configured using the zone
identifiers at the top of the display. The number of
zones available depends on the amplifier model and
configuration.
For each zone, configure the zone name, mono/
stereo setting, source assignment, volume settings,
restrictions, and compressor settings as required.
Use the Source menu to assign an input or input mix to
the selected zone. Selecting a stereo input for a mono
zone will automatically sum the stereo channels to
mono.
5.4.3 Output Setup and Routing
Open the Output tab to assign zones to amplifier
outputs.
Select the output to be configured using the output
identifiers at the top of the display. For each output,
configure the output name, polarity, output level,
routing, delay, EQ, speaker preset, and output mode as
required.
Use the Routing menu to assign a zone to the selected
output. For stereo zones, available routing options may
include left channel, right channel, or summed mono.
Use the Speaker Preset menu to apply the appropriate
output mode and speaker-specific processing for the
connected speaker type.
Caution: Lo-Z output mode is intended for speakers
with a nominal impedance of 4 ohms or higher.
Connecting speakers or speaker loads below 4 ohms
may cause the amplifier to enter protection mode or
may result in reduced performance.
5.5 GPIO Setup and Connection
PowerZone Connect PRO amplifiers provide a
configurable GPIO connector for external control and
trigger functions. GPIO functions may include standby,
mute, 12V trigger input, 12V trigger output, and
external volume control, depending on the selected pin
configuration.
GPIO pin functions are configured in the Settings
> GPIO menu. The GPIO menu displays each pin,
its available functions, and the currently selected
configuration. Refer to the on-screen descriptions and
tooltips when configuring GPIO behavior.
Caution: The GPIO connector must not be used for
any unintended purpose. Incorrect GPIO wiring or
configuration may damage the amplifier or connected
equipment.
Caution: Use shielded cable when connecting external
standby switches, mute switches, trigger wiring, or
potentiometers via GPIO.
The GPIO connector includes ground reference pins,
configurable control pins, and a 3.3V supply for external
volume controls.
* Pin 1 provides a soft ground reference for 12V trigger
and standby/mute input functions.
* Pin 2 can be configured for standby or mute control,
normally open or normally closed.
* Pin 3 provides a ground reference for external volume
control and trigger output functions.
* Pins 4 and 5 can be individually configured for external
volume control.
*Pin 6 and 7 can individually be configured for 12V trigger
input, external volume control, or no function.
*Pin 8 provides 3.3V power for external volume controls.

Note: GPIO Pin 1 and Pin 3 both provide ground
connections. Pin 1 is connected directly to the amplifier
chassis. Pin 3 is connected to the chassis through a 220
ohm resistor. The soft ground connection of Pin 3 is
potentially useful for managing ground loops that may
cause audible hum.
Note: GPIO Pin 8 has a low output impedance and can
supply a maximum current of 10 mA.
External volume control can be implemented using a
potentiometer connected to the appropriate GPIO pins.
Standby or mute control can be implemented using an
external switch connected to the configured GPIO pin
and ground reference. Refer to Diagrams 5R and 5S for
example wiring.

Connections
6. Connections
PowerZone Connect PRO amplifier rear panel
connections are illustrated in Diagrams 6A and 6B.
6.1 Mains Power Connection
PowerZone Connect PRO amplifiers 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 amplifier.
PowerZone Connect PRO 2U amplifiers incorporate a
front panel mounted power button. Press the button
once to switch the amplifier on or o. Ensure that all
signal, GPIO and output connections are made before
connecting the amplifier to mains power.
6.2 Input Connection
All PowerZone Connect PRO amplifier models provide
four (or eight) balanced and 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 configured via the
PowerZone Control interface. See Section 5 of this
manual.
Analog Inputs
PowerZone Connect PRO 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 with-
out input clipping. Input sensitivity options can be set
via the PowerZone Control interface. See Section 5 of
this manual.
Balanced input connections to the amplifiers are made
via male ‘Euro Block’ connectors. Connecting cables to
the supplied female input connectors is illustrated in
Diagram 6C.
Unbalanced input connections to the amplifiers are
made via RCA phono sockets connected in parallel
with the balanced inputs.
Digital Outputs
PowerZone Connect PRO 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 PRO amplifiers.
Note: See the Output Routing paragraphs of
Section 5.3.3 for more information on Digital Output
configuration.
Note: 75Ω RCA Phono cables specifically 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.
6.3 Output Connections
Output connections from the amplifiers are achieved
via male ‘Euro Block’ connectors. Ensure that speaker
connection polarity is correct throughout the
installation.
Supplied plugs are provided to block the center two
positions of the 4-pin output connector, helping
prevent accidental misconnections during installation.
For Hi-Z and Lo-Z speaker connections, positive (+)
amplifier terminals should always be connected to
positive speaker terminals and negative (–) amplifier
terminals always connected to negative speaker
terminals.
Output mode options (Hi-Z or Lo-Z) can be configured
via the PowerZone Control interface.
Note: see the Speaker Preset Menu Parameters of
Section 5.3.4 for more information on selecting Hi-Z or
Lo-Z output modes.
