Left Section  

1.   CH :

Channel Power (down = on)
Do not switch during recording.

2. PH/DYN/T: Phantom power, no mic power, T (AB) power
(Phantom power is normally 48 v, see layout A to change to 12 v).
3. ø: Phase (audio only).
ø = normal phase      REV = reverse phase
4. Mic/Line: Microphone or line level in.
5. Pad: Attenuator to reduce either mic or line input levels.
6. HP 1: High pass filter, pre-transformer.
7. HP 2: High pass filter, post transformer & preAmps.
8. EQ: Equalizer bypass. Affects HF, MF & LF filters, not HP filters.
9-12 A,B,C,D: Channel to mix bus assigns. L(left), R(right) indicate monitor & pan pot assignment.
13. LIM + LED: The limiter is a symmetrical peak detecting type & is completely out of circuit when switched off. Threshold: See (15). Attack & release times are preset internally (see layout A to change). The LED indicates limiter action.
14. PFL/AFL + LED: Pre fade listen or After fade listen (post fader). The switch is not momentary, the LED serves as warning that PFL or AFL is selected.
15. Thres: Limiter threshold. Clockwise = lower threshold.
16. O/L: Near overload indicator.


Right Section

17. Gain: Mic/Line preamp gain.
18. HF: High frequency amplitude control.
19. MF 500, 5k: Mid-frequency select.
20. MF: Mid-frequency amplitude control.
21. N/S: N = normal, S = side for M/S decoding.
'S' inverts phase to B & D busses allowing one pair of channels to be used with a M/S mic configuration and decoded to a L/R stereo signal.
(This is an option, see separate application note.)

22. LF:

Low frequency amplitude control.
23. PF/AF: Selects pre or after fader for Aux 1 send.
24. A1: Aux 1 send (the aux sends are not affected by the ABCD mix bus switches).
25. PF/AF:  Selects pre or after fader for Aux 2 send.
26. A2: Aux 2 send.
27. Pan (switch): Switching the pan switch to the left disengages the pan pot.
Crosstalk is therefore minimized and the output levels will remain equal.
28. Pan (pot): (L) = A & or C
(R) = B & or D

29.  Channel fader
