1. SCM810 – microphone channel gain controls 1-8
SCM410 – microphone channel gain controls 1-4
2. Easy to view LEDs – light is green when channel is active and red at 6 dB below clipping
3. Adjustable EQ – can adjust to reduce low-frequency signals, and boost or cut
high-frequency signals
4. Auxiliary Control and Input – for mixing external devices such as CD players (SCM810 only)
5. Master Control – to set overall level
6. Output Level LED Meter – indicates peak output signal and limiter action
7. Headphone Control and Output provides monitoring of overall mixer output (SCM810 only)
8. Power LED – lights green when unit is on
BACK
