Installation Notes
If there are any problems
with the gain structure,
and feel there is too much
hiss coming from the
speakers within the zone/s
adjustments of the GAIN,
HF and LF controls may be
required.
For each zone where they
may be an issue, check
that the HF and LF adjustments on the rear
panel are at unity. There are separate controls
for Paging, Gain as well as HF and LF.
As a point of reference, adjust both the HF
and LF so that the symbol ‘EDS’ is at the 9.00
position as shown here.
From this point, it is a simple matter of
adjusting both the HF and LF to gain the best
balance of signal to noise.
The level controls on the Q Matrix 88 operate
in 2db steps. It is advisable to make volume
adjustments slowly in order to avoid large
jumps in audio signal.

between the remote control panel and the
