Installation Guide

Conguration
• The Polarity menu enables the polarity of individual
amplier outputs to be reversed.
• The Limiter menu enables signal limiting to be to be applied
to individual amplier outputs.
Note: An output limiter can be used to restrict the peak volume level
from speakers connected to each output.
• The Output Mode menu enables individual amplier
outputs to be switched off or congured for Lo-Z or
Hi-Z modes. In Hi-Z modes, a high-pass lter can also be
congured and applied to the output.
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.
Settings Tab
The Settings Tab enables miscellaneous amplier settings to be
congured and installation data to be recorded. The Settings
Tab provides access to further sub-menus.
• The System Information menu provides text elds for the
recording of installation data.
• The Device menu records amplier specic information
such as the model number and rmware version. A rmware
update routine and identier button can also be found
under the Device menu.

• The Backup & Restore menu enables amplier
conguration data to be downloaded to an external archive,
and enables previously saved conguration les to be
uploaded and adopted by the currently connected amplier.
• The Power Management menu enables various automatic
switch-on options to be engaged. The Power Management
menu also offers timed Standby and Mute functions.
• The GPIO menu enables conguration of the multi-purpose
GPIO interface pins.
• The LAN menu enables conguration and reset of the wired
network options and parameters.
• The WiFi menu enables conguration and reset of the
wireless network options and parameters.
5.4 Setup and Signal Routing
Thanks to their network based conguration features,
PowerZone Connect ampliers 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 amplier outputs in
either Lo-Z or Hi-Z modes.
This versatility enables, for example, one amplier
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 conguring input, zone and
output routing. A general signal ow schematic is also
illustrated in Diagram 5f.
Input name. Type to edit.
Select an input sensitivity option.
Adjust input gain using the slider or the up/down icons.
The input level display should remain in the green band.
If it displays red, the input gain should be reduced.
Dene a mono or stereo input.
