5. Adjacent to the connector there is an M3 fixing screw remove & retain this screw then fit a 35mm
M3 hex spacer (supplied) in its place.
6. Push the 10-way VCA plug onto the PCB connector, aligned so the cable enters it from the rear of
the chassis (See Fig 9) check there is contact with all 10 pins.
7. Position the VCA modules 3-pin socket through the rear panel cut-out and secure using M3 screws
(both removed earlier) VCA Modules Installed to Channel 1&2
8. Replace the top panel.

Remote Level Plate Connections
The RL-1 is a remote control plate that allows the level of a specific channel to be remotely
controlled (in conjunction with the VCA-5). The RL-1 is compatible with UK domestic
electrical accessories and can be mounted onto a standard British flush or surface mounted
25mm deep back box.
As Fig 11 shows, the RL-1 is to be connected to a CX-A850 remote connector with a two-
core cable that has an overall screen. It is possible to connect a single remote control
module to control more than one channel simultaneously (Fig 11 right). As more channels
are linked the law of the control will be compromised resulting in an uneven control of
volume; this has proved to be of little consequence operationally.
14 Speaker Equalisation Modules
Each channel of the CX-A850 can have a speaker equalisation module installed so that its
output will be compensated correctly for a wide range of speakers.
Available Equalisation Modules:
- Bose
