Location of Jumper J1
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.
11 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: -
