For optimum performance, adjust this GAIN control so that the PEAK indicator LED lights occasionally. 2 LINE/MIC switch This switch toggles between MIC IN. Push this switch in (to MIC) when a microphone is connected to the MIC IN connector. Set this switch to LINE when a line source is connected to the LINE IN connector. 3 EQ The equalizer section provided on each input channel consists of LOW, LO- MID, HI-MID and HIGH controls at the following frequencies with the maximum range of ±15dB. HIGH : 12kHz HI-MID : 3kHz LO-MID : 300Hz LOW : 80Hz Frequency response will be flat when each control is set to the center.

Therefore, the signal can be output either to AUX 3 or AUX 4 as an auxiliary output, instead of using the stereo outputs. 2
