Multiple CPM paging microphones can be connected to a 36/50 when wired as the following

diagram shows, each microphone will require an external power supply (CPM-PSU): -

Microphone Gain Control

A pre-set gain control is provided adjacent to the XLR input connector. The gain can be

adjusted from 0dB to 60dB and this wide range of gain allows direct connection of high

output devices such as radio microphones without the need for additional attenuation. A high

overload margin is maintained at all gain settings.

Two band equalisation is provided for the microphone signal, these pre-set controls are

positioned alongside the rear panel input connector and gain control. The characteristics of

the equalisation are optimised for tonal correction of speech signals and the treble control

(HF) provides ±10dB at 5kHz with the bass control (LF) ±10dB at 100Hz.

Front panel controls for the Microphone level are provided for zones 1 and 2. The Utility

microphone level is adjusted by means of a rear panel pre-set. Rotating any mic level control

to the fully anti-clockwise position effectively turns the microphone off. The microphone

signals are routed directly to the output stage of the respective zone and mic signals are

totally unaffected by the operation of the music controls – including the remote level controls.

The mic gain control on the rear panel should be set at a level where it is not possible to

have excessive gain even when the front panel level controls are fully clockwise.

Fully automatic, voice operated priority is provided. This priority is activated by means of a

rear panel switch adjacent to the microphone tone controls. When a microphone is used, the

music signals will attenuate by approximately 30dB; after the announcement, the music

signals will restore smoothly to their former level.

The 36/50 is fitted with a utility output, primarily

intended to provide a signal for utility areas such as

toilets and foyers. The utility output has a limited

choice of music sources, selected by a PCB mounted

jumper J10 that consists of two movable links, jumper

J10 can be found approximately 25mm behind the

rear of the music mute connector. The 36/50 leaves

the factory configured to provide a music signal

derived from the Zone 1 music source selector (pre-

level control) however, J10 can also be configured to

set the utility music source to Line 1 input. Pre-set,

rear panel controls are provided for the microphone

and music levels. These controls do not function if

jumper J10 has been set to it's third option - the slave
