The Controls Channels 1 - 4
The Gain Knob
This knob sets how much of the source signal is sent into the mixer. Too high and the signal will distort as it overloads the channel. Too low, and
the level of background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer.
Setting the knob at 9’oclock gives approximately unity gain for the LINE input. Note that some sound equipment that is intended for domestic use,
operates at a lower level (-10dBV) than pro-audio gear and will therefore need a higher setting to get the same level.
Each channel features a RED peak level LED, this is set show at 0dB (0.775v) and is designed to indicate the onset of clipping (distortion), however
occasional flashing of this will be observed from very dynamic sources, without causing any undesirable effects.
FX Level Knob
This knob is used to control the level of the signal going to the effects send mixing bus.
It is POST EQ & POST VOLUME, if the Channel Volume or the Eq is adjusted, then the level of signal going to an effects processor will also be
changed.
Volume Knob
Use this to balance the mix & level of signal going to the Master Mixing Stage and outputs.
Tone Controls (EQ)
The 3 Band equaliser (EQ) section allows good manipulation of the frequency bands. It is particularly useful in live PA applications where the
original signal is far from ideal and where boosting and cutting of the right frequencies can dramatically improve the quality of the performance.
