: Installation and User Guide

For balanced microphones, connect the

cable screen to pin 1, the in-phase signal

(+) to pin 2 and the reverse phase signal

(-) to pin 3. For unbalanced microphones,

connect a wire link from pin 1 (ground) to

pin 3 inside the XLR cable mounted plug;

use pin 1 as ground (cable screen) and pin

2 as hot. Do not use the phantom power

facility with unbalanced terminations.

When setting the jumper(s) 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.

• Use a microphone that requires phantom power.

Paging Microphone

A dedicated paging microphone input is provided with adjacent gain control and equalisation

pre-sets. Once the input gain control has been set the paging mic level of each zone can be

optimised by adjusting the front panel mounted pre-set level controls. The Cloud CPM-4 &

CPM-8 zone paging microphones are available as an optional accessory, both microphones

feature zone selection switches allowing paging to all four or eight zones in any combination;

in addition a 'call all' button is provided for announcements to all zones. The zone select

buttons have push/on and push/off operation however, they can be internally configured to

automatically reset after an announcement has been made. A CPM microphone can be

internally configured to activate a pre-announcement chime, as well as an internal sounder

so that the chime is audible to the operator.

When using a single CPM paging microphone use the wiring diagram shown below: -

Up to 5 CPM paging microphones can be used with a Z4 or Z8 Venue Mixer, when wiring

more than one CPM paging microphone either the Z4 or Z8 Venue Mixers please use the
