1. CH1 MIC/LINE inputs (XLR/TRS combination socket, balanced / unbalanced)
Connect to a microphone, an instrument or other audio device. This socket supports balanced / unbal-
anced connections for both XLR and phone TRS plugs.
2. CLIP LED / GAIN knob
Lights up when the volume of input sound is too high. If it is lit, turn the GAIN knob to the left to lower
source the volume. The GAIN knob determines the basic volume for CH 1. Adjust this knob so that the
Clip LED seldom flashes when the input audio volume is at its loudest.
3. PAD -20dB switch
Turning the switch on will attenuate the sound input to CH 1. If you hear distortion or the CLIP LED
lights frequently despite the GAIN knob being turned fully to the left, then turn PAD on.
Note: Slide the fader to minimum before toggling the PAD switch on and off. Otherwise, a noise
spike may be produced.
4. PHANTOM POWER 48V d.c. LED
When this switch is pressed on, the LED lights up and +48V d.c. phantom power is supplied to the
XLR plug on CH1 MIC/LINE Input jack. Turn this switch on when using a phantom powered condenser
microphone.
