Installation Guide

Operation
7. Operation
Once all connections have been made and conguration
options selected, PowerZone Connect ampliers 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
amplier operation. Audio will be heard from any
connected speakers.
Note: PowerZone Connect ampliers will not switch on from
Standby Mode unless an input signal is present or a network or
external standby switch is operated.
Amplier outputs will mute if no input signal is present for
5 minutes, and the amplier 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 Menu. Amplier cooling fan speed
is temperature controlled. The fan will switch off when the
amplier enters standby mode.
7.1 Front Panel Indicators
PowerZone Connect amplier front panel indicators illuminate
to indicate the following operational states:
Status: Off – Mains power disconnected.
Green – Amplier 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.
7.2 Automatic Power Sharing
PowerZone Connect DSP ampliers incorporate a power
sharing feature that automatically shares the total power
available from the amplier’s internal power supply across each
pair of output channels. If one channel temporarily demands
more than the amplier’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 amplier’s
ability to deliver maximum power into dynamic loudspeaker
loads when playing music programme material.
