1. INPUT TRIM (GAIN SELECTOR)

3-way switch controls input level of both mono (Left) or stereo inputs. Select for nominal 0 dBm, -10 dBm, or -20 dBm (MIC) inputs.

2. PAN/BAL

For stereo inputs, use as a Left/Right volume balance. For mono inputs, use as a pan to place signal between Left and Right.

3. FADER 1 ~ 4

Adjusts the volume of the associated channel.

4. PEAK (PEAK INDICATOR)

The LED indicates when input signal to that channel reaches peak level. Set the input gain select trim so the LED will light only occasionally at peak level.

5. EFFECT (EFF SND)

Adjusts the level sent to the outboard effect.

6. EFFECT RETURN

Adjusts the level returned from the outboard effect.

7. POWER INDICATOR

The LED lights to indicate that the power is switched on.

8. PHONES

Adjusts the volume at the headphone output.

9. AUX
