Record Outputs

The REC outputs are via a stereo pair of RCA phono sockets on the rear connector. They carry the same signals as the Mix L and Mix R outputs.

Monitoring & PFL/AFL

The monitor section feeds the Monitor L & R outputs ( 3-pole 1/4” balanced jack sockets on the rear connector panel) and the headphones output (14).

The sources for the monitor section are:

•the 2-track input (15), its volume is controlled by the 2-TRK LEVEL control (16),

•groups 1 - 2 (17),

•groups 3 - 4 (18), and

•the main mix (13).

Any or all of these sources may be selected at any one time. The monitor signals (L & R) are passed to the monitor L & R outputs via the C/ROOM level pot (19), and to the headphones socket via the H/PHONES pot (20). The monitor L & R signals can be mono summed using the MONO switch (21).

The L & R 12-segment meters (22) indicate the level of the monitored signal, as selected by the monitor source select switches.

When any PFL or AFL button is pressed the meters display 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 (23) 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 (24).

Talkback

The talkback mic input is via an XLR (25) on the front panel.

The level of the talkback mic signal is controlled by the TALKBACK level pot (26). The signal is the fed to aux 1-4 and/or all four groups using the appropriate buttons (27).

PSU Monitor LEDs

These LEDS (28) confirm the presence of the correct voltage on the +48V and the +/-17V power rails in the console.
