Note:

The initial settings should only be regarded as a starting point for your mix. It is important

to remember that many factors affect the sound during a live performance, for instance

the size of the audience!

You are now ready to start building the mix and this should be done progressively,

listening carefully for each component in the mix and watching the meters for any hint of

overload. If this occurs, back off the appropriate Channel Fader slightly until the level is

out of the red segments, or adjust the Master Faders.

Remember that the mixer is a mixer, not an amplifier. Increasing the overall level is the

job of the amplifier, and if it is impossible to provide adequate level, it is probable that the

amplifier is too small for the application. Choose your amplifier carefully, and do not try

to compensate for lack of power by using the mixer to increase output level.

Note:

The level of any source signal in the final output is affected by many factors, principally

the Input Gain control, Channel Fader and Mix Faders. You should try to use only as

much microphone gain as required to achieve a good balance between signals, with the

faders set as described above.

If the input gain is set too high, the channel fader will need to be pulled down too far in

compensation to leave enough travel for successful mixing and there is a greater risk of

feedback because small fader movements will have a very significant effect on output

level. Also there will be a chance of distortion as the signal overloads the channel and

causes clipping.

If the gain is set too low, you will not find enough gain on the faders to bring the signal up

to an adequate level, and backgound hiss will be more noticeable.

This is illustrated below:
