your input by turning up the level of your audio source to the
highest possible operating level.

Input Sensitivity:
The input sensitivity setting determines the over-
all gain of the amplifier. Although you might me tempted to config-
ure your amp to get as much gain as possible (after all, you just
paid
lots of money for this little beauty), you should instead look
at your operating conditions and adjust the input sensitivity
accordingly.
First, check to make sure your mixer or console is being
operated at optimum signal-to -noise, without clipping the
output. (Refer to the owner’s manual for information on
how to check this.) Then, with your amplifier’s input sensi-
tivity set to the 26 dB position, turn up your amp’s level
controls until you achieve the desired level (loudness). If
you turn the level controls all the way up, and it’s still not
loud enough, check the following:
