1. BALANCED INPUT (MIC 1)
Electronically balanced input accepts a standard XLR male connector.
For use with balanced microphones
2. CHANNEL GAIN
This function is to adjust the volume of signal connection into each channel
and adjust the volume of output, together with the master fader.
3. HI EQ
This control gives you up to 10dB of boost or cut at 12kHz and above, and it is also flat
at the detent. Use it to add sizzle to cymbals, and an overall sense of transparency or
edge to keyboards, vocals, guitar, and bacon frying. Turn it down a little to reduce
sibilance, or to hide tape hiss.
4. MID EQ
Short for “midrange”, this knob provides 10dB of boost or cut, centered at 2.5kHz, also
flat at the center detent. Midrange EQ is often thought of as the most dynamic, because
the frequencies that define any particular sound are almost always found in this range.
You can create many interesting and useful EQ changes by turning this knob down as
well as up.
5. LOW EQ
This control gives you up to 10dB boost or cut at 80Hz and below. This circuit is flat (no
boost or cut) at the center detent position. This frequency represents the punch in bass
drums, bass guitar, fat synth patches, and some really serious male singers.
6. AUX IN
You can adjust the volume of AUX IN signal by this when connecting AUX IN.
7. EFF
This is normally derived after the EQ and channel fader (POST FADER, POST EQ),
and is used to set the effects level
8. VOLUME CONTROL
Sets the output signal. Turn clockwise to increase the signal or counterclockwise to
reduce it.
9. BALANCED INPUT (MIC 2)
Electronically balanced input accepts a standard XLR male connector
10. CHANNEL 3 MIC INPUT
To be connected via a 6.3mm stereo jack plug.
