2. LO CUT switch (ch. 1 ÷ 8)
This switch cuts bass frequencies below 75 Hz at a rate of 18 dB per octave. We recommend that you use the
LO CUT filter on every microphone application except kick drum, bass guitar, bassy synth patches or
recordings. These aside, there isn’t much down there that you want to hear and filtering it out makes the low
stuff you do want much more crisp and tasty. Not only that, but the LO CUT filter can help reduce the
possibility of feedbacks in live situations and it helps to conserve the amplifier power. Another way to use the
LO CUT filter is in combination with the LOW EQ on vocals during live performances. Many times, bass
shelving EQ can really benefit voices. Trouble is, adding LOW EQ also boosts stage rumble, mic handling
clunks, and breath pops.
3. CHANNEL GAIN control (ch. 1 ÷ 8 / 9 ÷ 16)
The gain control adjusts the input sensitivity of the mic and line inputs. This allows the signal from mics and
instruments to be adjusted to optimal internal levels. If the signals are plugged into the XLR input there is a 0
dB of gain with the knob turned all way down, rising up to 40 dB of gain fully up. When connected to the jack
input of any channels, there is 20 dB of attenuation all way down and 20 dB of gain fully up.
4. COMP compressor control (ch. 1 ÷ 8)
Each mono channel features a single-control compressor, able to adjust the overall dynamic range of the signal and to
increase its loudness. When rotating the control to the right, the loudest signals are reduced in order to avoid clipping,
while the quietest parts are boosted, producing a smooth, unified sound with no excessive peaks or distortion.
NOTE: avoid setting the compression too high, as the higher average output level that results may lead to
feedback.
5. COMP indicator (ch. 1 ÷ 8)
The COMP LED lights when the signal compression effect is engaged (it depends on the position of the
control and on the audio signal level).
6. EQ section HIGH control (ch. 1 ÷ 8 / 9 ÷ 16)
This control gives you up to 15dB boost or cut at 12KHz with a “SHELVING” curve shape. Use it to increase or
reduce the sound “clarity” or “brightness”.
7. EQ section MID LEVEL control (ch. 1 ÷ 8)
This control gives you up to 15 dB boost or cut at the frequency determined by the FREQ knob (see FREQ
next) with a "PEAKING" curve shape. Use it to add or reduce the sound "presence".
8. EQ section FREQ control (ch. 1 ÷ 8)
This knob ranges from 100 Hz to 8 kHz and determines the center frequency for the MID EQ. This allows you
to select the precise narrow band of frequencies you want to be affected by the MID EQ.
9. EQ section LOW control (ch. 1 ÷ 8 / 9 ÷ 16)
This control gives you up to 15dB boost or cut at 80Hz with a “SHELVING” curve shape. Use it to increase or
reduce the sound “punch”.
10. AUX 1 control (pre) (ch. 1 ÷ 8 / 9 ÷ 16)
This control sends the channel signal to the AUX 1 output. This signal is always pre-fader, i.e. it is
independent by the position of the FADER LEVEL control.
