Internal jumpers allow either zone to operate in
mono (see Figure 4). In the mono mode of
operation, both the left and right output sockets
carry the same mono signal and either or both
sockets can be used. Separate remote control of
the mono signal on the left and right output
socket can be achieved by wiring two RL-1
control plates to the 4 pin connector as shown in
Figure 2 When this feature is used, we suggest
that the respective front panel level control is
defeated (see section 4.3).

6 Priority
When a Juke Box or Spot Announce Player is connected to the CX133, fully automatic
priority over any selected line input can be achieved by using the Line 3 input and
configuring the relevant internal jumpers (see Figure 3). When this mode of operation is
selected, the unit will operate normally until a signal is detected on line 3 and this causes the
selected signal (usually background music) to mute, allowing the signal on line 3 to operate
with priority. Once the signal on line 3 ceases, the selected signal will smoothly restore to its
former level. The time taken for the selected signal to be restored can be set at 3, 6 or 12
seconds by fitting the appropriate jumper (J5) on the printed circuit board. The line 3 priority
option can be configured to operate on either or both zone outputs.

The Line 3 priority does not operate on the Utility Output, however we have included the
option to select the utility zone to operate with Line 3 priority if preferred – please contact our
