If the mixer has a CPM paging microphone installed, you have the option to power the

microphone with the 'CPM-PSU' external power supply. This will reduce the load on the

system by 40mA. If a power supply failure occurs switch off the mixer and disconnect the

remote modules, the mixer should be left off for approximately 30 seconds to allow it to

reset. Check the wiring and total current consumption of the external active devices before

reconnecting the power and if the problem persists contact our technical department.

Microphone Priority over Facility Input

Every vertically oriented zone board has a jumper marked J4 - this jumper sets the

microphone over facility signal priority. In the OFF position (default) all microphones will not

override the signals of the facility input (i.e. AE-1, DM-1 or LM-1). In the ON position, MIC 1,

MIC 2 and the paging mic have a 30dB priority over the facility input.

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.

Remote Music Mute – Fire Alarm Interface

In certain circumstances, there may be a requirement to mute the music signals via a fire

alarm control panel in an alarm condition. The Cloud Venue Mixer provides a facility to mute

the music signals by connecting the two pole music mute connector to a pair of relay

contacts that are controlled by the fire alarm control panel. The jumper J4 on the mother

board (adjacent to the power transformer) selects N/O (normally open – default) or N/C

(normally closed) contact arrangements. The two-wire connection should not be connected

to any other circuit or voltage. In most instances, the fire alarm company will provide the

relay. All the microphone facilities operate normally when the music mute is operating.

Installing RSL-6 or RL-1 Remote controls

The remote control plates, RSL-6 and RL-1 are compatible with UK domestic electrical

accessories and can be mounted onto a standard British flush or surface mounted 25mm

deep back box. Two-core cable with overall screen should be used to connect the remote

controls to the Cloud Mixer; because

both functions are voltage controlled,

a cable length of up to 100 metres can

be used. When using the RSL-6

remote control plate, the 'music

control' switch (on the mixer rear

panel) should be in the 'remote'

position. If you propose to use the RL-

1 remote level control on any zone,

set the 'music control' switch to the

'remote' position and the PCB

mounted jumper J1 on the respective

zone board to the 'FR' position to

allow front panel control of the music

source.

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.
