The
AVA-
1
204
and
AVA-1404
do
not
have Volume Level controls,
Therefore,
all
of your audlo
system
level controls
are
made
at
the
head
unit
or,
in the case
of
the
subwoofer
output,
at the
amplifier
(or
its
remote
control unit) dedicated
to
the subwoofer channel.
In the case of the amplified model AVA-1404,
the
amplifier in the
equalizer
unit adds a very large power boost! So when you first
turn
on the system, be sure your head unit volume control is set at the
minimum
level. Then you can
raise it slowly to
see the effect the
new
equalizer has on the overall
system
volume level.
