Cloud Electronics CX163 - Manual (Page 9)

5.1 Sensitivity and Gain Control
All six line inputs have pre-set gain controls which are accessible on the rear panel, adjacent
to their respective input sockets. The input sensitivity can be varied from -18dBu (100mV) to
+ 6dBu (1.5V). The pre-set gain controls should be set so that all the input signals operate at
the same level (0dBu) within the CX163 to give the music level controls an optimum control
range.
5.2 Music level control - Local or Remote
The music level in a zone can be controlled from
either the front panel, or a remote control plate
located up to 100m from the CX163. The CX163 is
compatible with the RL-1 remote level control plate.
RL-1 remote control plates can be mounted onto a
standard British flush or surface mounted 25mm
deep back box. Each RL-1 needs to be connected
using two-core screened cable. Connection details
are shown in the adjacent diagram. Remote
controls will be operational once correctly connected
to the unit, there are no further operations required.
When a zone is in
the mono mode,
it is possible to
connect two RL-1
plates to that zone
and use them
to independently
control the levels of
the left and right
outputs of the zone.
In order to do this,
the RL-1 plates
should be connected
as shown adjacently.
The CX163 can be configured to
bypass the front-panel level
controls by setting internal
jumpers J13 (Zone 1) and/or J12
(Zone 2) to the ‘DEF’ position.
