L, R & C Outputs

Each of the 3 main mix busses, Left, Right and Centre, has its own insert point. These are located on the rear connector panel. Each mix bus has its own Fader (16) following the insert point in the signal path.

The post-fader signal for each bus is then routed to the following places:

•its main output XLR on the rear connector panel,

•feeds to the matrix 1- 4 buses (17),

•the REC/ALT output section,

•the MONITOR SOURCE select switches L-R (18) and C (19).

A mono sum of the L & R outputs can be routed to the C output via the L-R TO CENTRE switch (20).

REC/ALT Outputs

The REC/ALT output is a stereo pair. Each of the 2 channels (L & R) has 2 output connectors on the rear connector panel: an RCA phono socket and a 1/4” jack.

The three feeds to the REC/ALT section are from the L, R & C main faders (16). The C switch

(21)feeds the C signal to both L & R channels. The MONO switch (22) sums both the left and right channels together.

The LEVEL pot (23) feeds the stereo signal to a limiter which can be enabled by the LIMITER ON switch (24), the adjacent LED indicates when the limiter is active.

The stereo signal is then fed to the rear connector panel.

Monitoring & PFL

The monitor section feeds the control room L & R outputs (on the rear connector panel) and the headphones output (right hand front of console).

The sources for the monitor section are:

•the 2-track input (25), its volume is controlled by the 2-TRK LEVEL control (26),

•the centre mix, C (19), and

•the main mix, L-R (18).

Any or all of these sources may be selected at any one time. The monitor signals (L & R) are passed to the control room L & R outputs via the C/ROOM level pot (27), and to the headphones socket via the H/PHONES pot (28). The monitor L & R signals can be mono summed using the MNO switch (29).

The L & R 12-segment meters (30) indicate the level of the monitored signal, as selected by the monitor source select switches. The CENTRE meter (31) monitors the Centre mix output except when any AFL or PFL button is pressed.

When a PFL or AFL button is pressed the CENTRE meter displays the pfl/afl signal level, and the pfl/afl signal is routed to the control room outputs and to the headphones. This signal replaces the normal monitor signal. The PFL/AFL LED (32) illuminates when this is happening.

Note: the 2-track input may also be routed directly to the main L-R mix via the 2 TRK TO MIX switch (33).

Master Mutes

These four switches (34) will mute any input modules which have been assigned to them.
