∙Adjust the input gain until the meter is just reaching the amber section (0dB) at a typical maximum source level. This allows sufficient headroom to accommodate peaks and establishes the maximum level for normal operation (but see note below).
∙Repeat this procedure on other channels as required.
∙If you cannot obtain a satisfactory setting, e.g. the gain con- trol is right at the extreme low end of the scale on Microphone Input, and +48V powering is not required, try using the Line Input instead to give an extra 20dB range.
∙Listen carefully for the characteristic sound of ‘feedback’. If you cannot achieve satisfactory input level setting with- out feedback, check microphone and speaker placement and repeat the exercise.
∙Build up the required individual monitor mixes by feeding the selected channels to the monitor outputs using the channel monitor send controls. The corresponding output faders should be initially set at the ‘0’ mark. Listen care- fully for each component in the mix and watch the respective output meter for any hint of overload. As more channels are added to the mix, the meters may move into the red section. Adjust the overall level using the Output Faders if necessary, or back off the appropriate channel faders until the level is out of the red segments.
Note: The level of any source signal in the final output is af- fected by many factors, principally the Gain control, Channel Fader and Output Fader. You should try to use only as much microphone gain as required to achieve a good balance be- tween 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. 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.
Microphone Placement Careful microphone placement and the choice of a suitable type of microphone for the job is one of the essentials of suc-
