CAM8PRO Front Panel
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 (150 Hz 12dB/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. 0VU =
+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 19 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 (head-
phones on CAM8PRO only). (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 mixer’s 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).
