2 CHANNEL AMPLIFIER - 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. 2 CHANNEL AMPLIFIER - APPLICATIONS PLA2988 Car stereo system 1ii DD w u 0 ~ ~ ~~~ ~::~~~E.JIII,,~_~~ ~ ~':I sa~Eq UN~I'U ~~~~ LINEOOTl'lIT IlAHEQ LOW H'GH LEllEl ~- ~ 0 ~~~ o~ STEREO MODE 0 0 ~~~~~ ~~~ I(IXIXI)I 11- -I I !IKIp~1IIEq SPEAKE" OIJTPUT POWER INPUT FUSE I(I)(Il(il(il I 0 -CH2. -OH1+ o 0 0 0 0 L BRiDGED---1 "W ~" '"' 11- -I I 0 MONO MODE 0 ~~~~~ 0 ~~~ I(IXIXI)I -I I sap~1IIEq SPEAKER OUTPUT I(il(il(il(il l -CHZ+ 0 -0"1. o POWER INPUT FUSE 11- 0 0 0 0 L DRiOOED---1 "W ~" '"' 11- -I I 0 Subwooflor 04-1.0"",,"

has
RCA
connections for
low
level inputs.
Low

is
carried
through
RCA

is
preferred
to
use
low

to
the

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.

sequence
has
been
performed, set
