The talkback mic input is on the rear connector panel.
The level of the talkback mic signal is controlled by the LEVEL pot (35). The signal is the fed to
all groups, aux 1-2, aux 3-4, aux 5-6 and aux 7-8 using the appropriate buttons (36).

panel.
Each has its own level control (37), and each may be routed to the L-R main mix or to groups 1-

PSU Monitor LEDs
These LEDS (39) confirm the presence of the correct voltage on the +8V and the +/-17V power
