METER BRIDGE (audio)

1.  DYN/PH:

Dynamic or phantom power (48 v)
Dynamic is no power.

2.  Mic/Line:

Microphone or line level in.  Switching to line 

automatically turns off mic power.

3.  ø:

Audio phase; N = normal phase,

R = reverse phase

4.  Pad:

Attenuator to reduce either mic or

line input levels

INPUT CHANNEL

1.   Gain:

Mic/line preamp gain

2.   HP 1:

High pass filter (see specs)

3.   HP 2:

High pass filter (see specs)

4.   O/L:

Near overload indicator

5.   PFL:

Pre fade listen 

6-9.  A,B,C,D:

Channel to mix bus assigns:  L (left),
R (right) indicate monitor & pan pot 
assignment (center position is off)

10.  LIM+LED:

The limiter is a symmetrical peak
detecting type & is completely out
of circuit when switched off.
The LED indicates limiter action.

11.  Thres:

Limiter threshold:  Clockwise = lower 

threshold

12.  Pan (switch):

Switching the pan switch to the left 
disengages the panpot. Crosstalk is 
therefore minimized and the output
levels will remain equal.

13.  Pan (pot):

(L) = A & or C

(R) = B & or D

14.  Channel fader
