1. I nstrument Inputs 1 and 2 (Inst) – These front-panel connectors provide instrument-level inputs for channels 1 and 2.
Each of these two inputs will accept a high-impedance instrument level signal on an unbalanced 1/4" plug. Set the
Mic/Line - Instrument switch
2. M ic/Line - Instrument Level Switches (
channels 1/2 between the front-panel Instrument inputs
3. L ED Clip Meters (Clip) – These red LEDs illuminate when an input signal reaches a sustained clipping level. Reduce
the channel's Input Gain level
4. L ED Level Meters – These green LEDs illuminate when an input signal of -40 dBFS is present at the corresponding input.
5. M ic/Instrument Gain/Pad 1-8 (Mic/Inst Gain Pull -20dB) – These knobs adjust the input gain level for channels
1 through 8. Pulling the knob out will engage a 20 dB pad on the Mic and Instrument input. Pushing the knob in will
disengage the pad. (Note that the level controls only affect the XLR mic and front panel instrument inputs, but do not
affect the line-level inputs.)
6. P hantom Power Switches (Phantom Power) – Pressing these switches activates the phantom power circuitry for the
corresponding group of four mic inputs (1 through 4 or 5 through 8), illuminating the Phantom Power LED
48V power to the four associated XLR inputs
7. P hantom Power LED – These red LEDs light to indicate that the corresponding phantom power switch
pressed, applying +48V phantom power to the selected group of four mic inputs.
8. H eadphone Output Levels (
9. H eadphone Outputs (
and are controlled by the headphone output knobs
rear-panel outputs 1/2 while the second headphone jack outputs the same audio signal as rear-panel outputs 3/4.
10. Main Output Level (Output) – This knob controls the main output level (output pair 1/2).
11. MIDI Input LED (MIDI In) –This green LED lights when MIDI data is present at the MIDI input
12. MIDI Output LED (MIDI Out) – This green LED lights when MIDI data is present at the MIDI output
13. P ower Switch (
The unit must be connected to the external power supply.
14. P ower LED (Power) – This blue LED lights when the power switch
