Using the mixer channel functions

High-pass filter (HPF)

Press the HPF switch to turn the high-pass filter ON and cut frequencies of 80 Hz or less by –12 dB/octave. The high-pass filter affects inputs from both MIC and LINE input jacks, but it is especially effective when using mics for reducing unwanted noise from wind and breathing.

CAUTION

Even if there is no meter indication or no signal is being output despite the fact that a signal is being input, do not raise the faders carelessly. The operation of other switches or features could cause a loud signal to be output suddenly, possibly damaging speakers or other equipment. Sudden loud noises could also harm your hearing.

The best settings for audio quality are when the input meter “0” indicator lights, and the channel fader or ST fader is set in the range around 0 (where the fader scale on the mixer is highlighted). If the fader is set to an extremely low value, we recommend lowering the amp volume and then raising the fader. On the other hand, if the fader is too high, we recommend raising the amp volume and lowering the fader.

EQ

Channels 1–6 have 3-band equalization (EQ) with HI, MID and LOW frequency boost and cut adjustment ranges of ±15 dB.

The HI band is a shelving EQ. Use the EQ HI knob to boost or cut the frequency band above 12 kHz.

The MID band is a peaking EQ with 2.5 kHz as the central frequency. Use the EQ MID knob to boost or cut mid frequencies.

The LOW band is a shelving EQ. Use the EQ LOW knob to boost or cut the frequency band below 100 Hz.
