If the signal cannot be increased with the
Input Gain
knob at 2–3 o'clock, make sure the
input is not set to
Line
.
If Channel Volume Is Too High
If a channel is not clipping but the channel slider level control must be set below the -20
dB position to achieve the proper volume level, the
Input
Gain
control setting is too high.
Set the channel slider control knob to the 0 dB position and adjust the
Input Gain
control
until the desired volume level is achieved. Reduce the
Input
Gain
by turning the knob
counterclockwise.
If the signal cannot be reduced below clipping with the Input level control at minimum
(and the input source is not a microphone), change the Input to
Line
to pad the signal to
a lower level, set the channel slider control knob to the 0 dB position and adjust the
Input
Gain
control until the desired volume level is achieved.
Adjusting Compression Settings
A compressor reduces the dynamic range of a signal. This effect is perceived as quieting
loud sounds and boosting quiet sounds.
Note:
Some microphones are very low output. The mixer will not be able to completely
compensate for the low level but will be able to provide a usable output signal. A
decent dynamic microphone output level is approximately -55 dB. Check your micro
-
phone’s specifications.
