TURN
ON
SwiTCH
The
"REM"
setting is the best
way
to turn the unit on and off but if you
do
not have a
REMOTE
output wire from your
head-unit then you
will
need to use either the
"AUDIO"
or
"DC OFFSET"
setting.
Not
all
head-units are the same
this is
why
we
provide three different Turn On options.
You will need to select the setting that works best with your
head-unit.
(The
AUDIO
&
DC
OFFSET
setting are to be used with the Hi-level connections below.

The
"REM"
setting is used when
your
head-unit has a

output wire.

The

does not depend on music as the

Must

Hi-level

for
this
setting.
AUDIO
L
The
"AUDIO"
setting senses the music signal to turn on the amplifier. This setting
will
work
with any head-unit.
In
this setting the amplifier will
only turn on when it senses music, so even
if
your
head-unit is on but at
"0" volume the amplifier will
not turn on. Must use
RCA
input for
this setting.
HI-LEVEL
CoNNECTIONS
If
your
head-unit does not have
RCA
connections then you
will
need to use the Hi-level input connector (provided)

CoNTROL
Before connecting the remote, it
will
be necessary to find a mounting location
that
will
be
easy
to access for adjustment.
Once
you select
your
mounting
location, you
will
need to run the control wire from the remote to the amplifier.
To
avoid possibility
of
induced noise from the vehicle's electrical system (i.e.
popping noises
or
engine noise), run the cable from the remote to the amplifier
away
from the
vehicle's electrical wiring.
FINE

THE
SYSTEM
Fine tune the amplifier's input sensitivity.
GAIN
The gain sensitivity control for the amplifier is located on the front
panel.
This gain control has
rnrzr
been
included to allow adjustment to properly match the output
of
the radio. This is one
of
the most
~
misunderstood adjustments. By rotating the control in the clockwise direction, the amplifier's
Ml~
~AX
input
will
become more sensitive and the music
will
play louder. This is not a volume control and
you will not get more
power
out
of
the amplifier in the maximum position!
It
may seem
to deliver more output, but
actually the system is only playing louder faster as you turn the volume control on the
radio. Ideally,
to properly
level
match the system the goal is to achieve maximum output from the amplifier without
distortion at about
314
of
the
volume
control.
To
determine if the amplifier's gain is set properly, turn the system on and
slowly
increase the volume
control. You
should be able to use about
314
volume before the system gets loud but without distortion.
It
is very important
when making
these adjustments that you
do
not
over
drive the speakers (at point
of
distortion) which
will
cause
permanent
damage
to the speakers. If
you are unable to achieve
314
volume before distortion you will
need to
adjust the gain control (in this case you would reduce the gain). The gain control
should
be adjusted very slowly.
It
may
help to have another person to assist you
by
adjusting the gain controls while you
listen
for distortion.

ADJUSTING
THE
X-OVER
AND
BAss
BoosT
The amplifier is equipped with a built-in variable crossover network which
allows
you to select
the crossover point.
If
you are using this with another amplifier which has a Hi-pass setting
you
may
want
to match
or
slightly over-lap the x-over points.
The
amplifier is equipped with a built-in variable bass boost network which allows you to select
the gain
at
45Hz.
When
increasing the
level
you
will
notice more energy in the
lower
frequencies. Again there is no specific setting for this and
your
preference should be the
deciding factor
for
the
level
setting.
