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.
20 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.
21 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.
22 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.
