If you did not connect an input source
to every jack or do not want to mix ev-
ery input source connected to the mix-
er’s input jacks, you do not need to
follow all the steps in this section. Af-
ter you decide which source(s) you
want to preset and mix, use this table
to determine which steps to follow.
Notes:
While you adjust the input signal
levels for channels 1, 2, and 3, ei-
ther use the headphones or turn
up the receiver/amplifier’s volume
to a comfortable listening level
(not necessarily the final usable
level).
Do not play a quiet portion of mu-
sic while you adjust the volume
levels, otherwise the volume lev-
els for channels 1, 2, and 3 will be
overdriven during the loud por-
tions of the music.
