MUSIC EQUALISATION
A 14 band graphic equaliser is provided for music equalization. The graphic
can boost or attenuate the music signals on all channels by +12dB (1/4 to 4
times). The graphic equaliser is located behind the top front panel. The
panel is removed by undoing the two large locking bolts on the rear of the
unit. Turn these anti-clockwise until the front top panel is released (support
the front panel whilst undoing the locking bolts).
To adjust the equalisation setting move the slider controls up or down to
increase or decrease the gain at that frequency band. The overall setting is as
viewed by the slider positions.
MICROPHONE INPUT
A paging microphone input is provided
on the rear of the unit (see diagram
below). The microphone input socket
is a 9 way “D type” connector. Pre-
wired and tested paging microphones
are available from Semelab.
The input gain control for the microphone is located
underneath
the
top
front
cover
(see
MUSIC
EQUALISATION section). The gain control is shown
opposite. Rotating the control clockwise increases the gain.
Indicators are provided to assist setting up the microphone
levels. The green indicator indicates the presence of a
suitable microphone signal. The orange indicator indicates if
the microphone gain setting is too high.
