Loudspeaker Connection
Note: Use only 100V or 70V (Selectable) Line Loudspeakers
Two loudspeaker outputs are provided. The output marked ‘Music/speech gives an output at all times,
reproducing any signal input into the amplifier. The output marked ‘Speech Only’ will only reproduce a
signal during a priority condition, therefore an output from this connection will be present when
Microphone is in a priority condition. this means that only the ‘Ding Dong’ chime and the signal from one
of these microphone inputs will be presented to this output.
Low Impedance (8
O
)
This output allows connection of standard low impedance loudspeakers, the minimum load impedance
must be 8
O
, when two or more loudspeakers are use ensure that they are wired in such a way that the
load impedance is between 8
O
and
16
O
.
Connecting a Mixer Amplifier to a Power Amplifier
These amplifier can be connected using phono to phono leads from the mixer amplifier PRE out to the
power amplifier input phono socket. further power amplifier Can be connected by connecting from the
output of first power amplifier to the input of the second. up to three power amplifier can be connected in
this way.
If the Two Zone feature is required. the manual priority terminals must be used. connecting the priority
terminals from the mixer amplifier to the first power amplifier. up to three power amplifier can be
connected in this way.
VC A noise gate
The mixer amplifier are equipped with a VOX in master section. The input level which is required to
open the noise gate (S601 on the VR PCB-fixed on the front panel). When using the noise gate ( on )
then the S/N ratio can get more than 75dB for MIC inputs and 80dB for Aux / CD inputs.

Single unit operation
For single unit operation, set the mode selector switch (SW403,SW404) Located on the PCB to
the “ STAND ALONE” position.
Three unit operation
For
two or three unit operation, one unit must be designated the master unit, this can be done by
the mode selector switch to the “ MASTER “ position. All other units must be switched to “SL AVE”
mode.
