46/50 Integrated Mixer Amplifier Setup And Installation Guide

CLOUD ELECTRONICS LIMITED

6.6 Microphone Level Controls

Each zone has separate front panel mounted level controls for Mic 1 and Mic 2. The level

controls allow the user to adjust the microphone signals to a suitable level in any zone; rotating

any Mic level control fully anti-clockwise effectively turns the microphone off.

All microphone signals are routed directly to the respective power amplifier stage, and are

therefore totally unaffected by the music controls and line 6 priority. Mic 1 and Mic 2 rear panel

gain controls should be set to a level where it is not possible to have excessive gain even when

the front panel level controls are fully clockwise.

6.7 Microphone Priority

Independent, automatic voice operated priority is provided so that 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. If microphone over music priority is not desired

set internal jumper J12 to the 'OFF' position. PCB location of jumper J12 is shown below: -

A second microphone priority allows the signals of Mic 1 to mute those of Mic 2. This Mic 1 over

Mic 2 priority in each zone can be defeated by removing a diode from the PCB; D30 for Zone 1,

D25 for Zone 2, D22 for Zone 3, and D19 for Zone 4.

When removing diodes D19, D22, D25 or D30 or setting jumper J12 please ensure that you:

• Remove the mains cable from the rear of the product before removing the top

panel.

• Only reassemble the unit using screws identical to the original parts.
