3.1 FRONT PANEL
1.
Main/Auxiliary Bus Selector (one per channel)
A 4-position switch which selects destination of channel input. Input can berouted 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 (100Hz 18dB/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 = +4dBm.
This meter can be set to indicate the signal level of either the main or auxiliary 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 monitors AUX bus.)
11.Power Indicator LED
LED displays mixers powered state. Lit when power is on. Not lit when power is off.
