34. +4 / -10 Buttons
These buttons, located on each stereo
input channel, are used adjust the input
sensitivity of the corresponding channel,
which will adapt the mixer to external
devices which may
operating levels. If the input source is -
10 dBV (consumer audio standard), it is
best to engage the switch, allowing the
signal to be heard. If the input source is
+4 dBu (professional audio standard)
the corresponding input channel's button should
be disengaged to ensure the integrity of the Mixer's
circuitry. If you are unsure of the source's operating
level, we suggest leaving the switch disengaged until
you test the source's signal. You can then engage if
necessary (if the level of input is obviously too low).
