NSTALLATION AND OPERATION MANUAL

4.

Carefully position the VCA module on to the 10 pin connector making sure that 
both rows of pins engage in the pcb mounted socket.  This can be verified by 
checking that the 3mm fixing hole perfectly aligns with the mounting spacer.

5.

When you are satisfied that the VCA module is correctly fitted, secure the module 
with the supplied M3 screw.

6.

If you wish to bypass the respective front panel zone level control, the adjacent 
jumpers can be configured as detailed on the PCB.  This would remove the front 
panel level control from the circuitry, leaving the remote level control to operate 
independently.

7.

Refit the top panel.

Remote Level Plate

A remote level plate complete with control is supplied with each VCA module, this can be
fitted directly onto a standard UK electrical single gang mounting box (recessed or
surface) with a minimum depth of 25mm (not supplied).  2 core screened cable  must be
used to link the remote level control to the CX233.

When the remote level control facility is being used, it may be desirable to defeat the front
panel zone level control on the CX233 and this can be done by configuring an internal
jumper.

Optional DC Power Supply

6.01

Optional DC to DC Power Supply.

The DC supply kit is supplied with the following parts.

1 x NMXD 2415 DC to DC converter
2 x 1/4" PC mounting spade terminals
1 x PC mounting fuse holder
1 x 20x5mm T800mA Fuse
1 x 4 pin XLR connector with leads
2 x M3 fixing screws with nuts and washers
