1. Main/Auxiliary Bus Selector (one per channel)

A 4-position switch which selects destination of channel input. Input can be
routed to: a) the main bus (M-up, A-down); b) the auxiliary bus (M-down,
A-up-shown at right); c) both the main and auxiliary buses (both up);
or d) neither bus (both down).

2. Channel Volume Control Knob (one per channel)

Controls the volume of the channel input to any and all outputs simultaneously.

3. Low Cut Switch

Helps eliminate low frequency noise (100 Hz 18 dB/octave).

4. Main Output Compressor/Limiter Switch and LED

Note: Works only on main bus. Reduces distortion of the main output (due to clipping) by
controlling its dynamic range. When the LED (red) is lit, the Compressor/Limiter is on.
The brighter the LED, the more the signal is being compressed.

5. Main Output Volume Control Knob

Controls the output signal volume of the main bus.

6. LED Bar Graph Output Meter

Displays output signal level in decibels, ranging from -18 (green) to +12 (red) VU.
0 VU = +4 dBm. This meter can be set to indicate the signal level of either the main or aux-
iliary bus and to indicate either the average or peak signal. (See page 18 for details.)

7. Threshold Control

Screw-pot adjustment sets the signal level (-20 to +20 VU; factory setting is 0 VU) at which
the Compressor/Limiter becomes active.

8. Ratio Control

Screw-pot adjustment sets the amount of compression (0-100%; factory setting is 100%)
of the signal above the threshold.

9. Auxiliary Output Volume Control Knob

Controls the output signal volume of the auxiliary bus output and to the headphones.
(There is no connection between this bus and the Compressor/Limiter.)

10. Headphone Jack

A 1/4 inch-diameter TRS mono-only jack for the connection of headphones. (Only moni-
tors AUX bus.)

11. Power Indicator LED

LED displays mixerʼs powered state. Lit when power is on. Not lit when power is off.

12. Power Switch Button

Push button to turn unit on (“in” position); push again to turn unit off (“out” position).
