SPEAKER OUTPUT CONNECTIONS You do not need to make any adjustment for the input connection of amplifier before you connect the speaker output. * Connect right and left speaker wire to corresponding speaker output terminals of the amplifier. * Be sure to have the positive wire from the speaker to the positive speaker terminal of the amplifier and the negative wire from the speaker must connect with the speaker terminal of the amplifier. Reversing any of these connections will result in the speaker cones moving out of phase which causes bass cancellation. LEVEL CONTROLS Turn the VOLUME control on the amplifier to Min initially.

Insert a CD or tune to a radio station and slowly turn up the amplifier VOLUME control until you hear some distortion, and then back it off for clean sound. 11

APPLICATIONS
INPUT
CONNECTIONS
*
This
amplifier
has
RCA
connections for
low
level inputs.
Low
level signal
is
carried
through
RCA
cables.
it
is
preferred
to
use
low
level inputs
to
the
amplifier
if
the
head
unit
is
equipped
with
the
low level outputs.
SPEAKER
OUTPUT
CONNECTIONS
You
do
not
need
to
make
any
adjustment for
the
input connection of amplifier before
you
connect the speaker output.
*
Connect right
and
left speaker wire
to
corresponding speaker output terminals of
the
amplifier.
*
Be
sure
to
have
the
positive wire
from
the
speaker
to
the
positive speaker terminal
of
the
amplifier
and
the
negative wire
from
the speaker
must
connect with
the
speaker
terminal of
the
amplifier. Reversing any of these connections will result
in
the
speaker
cones
moving
out
of
phase
which
causes
bass
cancellation.
LEVEL
CONTROLS
Turn
the
VOLUME
control
on
the
amplifier
to
Min
initially.
Once
the
initial
power
sequence
has
been
performed,
set
the
CD
/
RADIO
volume
control
to
roughly
80
% of full. Insert a
CD
or tune
to
a
radio
station
and
slowly turn
up
the amplifier
VOLUME
control until
you
hear
some
distortion,
and
then
back it off
for clean sound.
