Music Source Select
Each zone has an independent source select control. The three position switch is used to
select the desired music signal. Use the supplied label pack to identify the signal sources on
the front panel. Line 3 input can be configured to have priority over any other selected signal,
see section 6 for full details. The Utility output can operate with the Zone 1 music
programme, Line 1 input or just the microphone; see section 13 for full details.
4.3
Music Level Control, Local or Remote
A front panel mounted music level control is provided for each of the two main zones.
Remote control of the Zone 1 and Zone 2 music level is possible by connecting a remote
level control plate (RL-1) to the 4 pole connector on the rear panel of the CX133 (see
connection diagram Figure 1 below). Either or both of the two main zones can operate in the
‘split’ mode where two remote level plates can be wired to control the left and right outputs
independently. When operating in the ‘split’ mode, the respective zone of the CX133 should
be configured to operate in the mono mode (see section 5 'Mono Operation'). The front panel
level control can be defeated by configuring the relevant internal jumpers, see Figure 3 for
full details. Use two core screened cable to connect the remote level plate (maximum length
100metres).
Full wiring details are also printed on the underside of the CX133.
