INPUT/OUTPUT
CONFIGURATIONS
Because
this
is a one channel
amplifier,
if
both
left
and
right
inputs
are used, they are mixed to mono, which is
useful
for
subwoofers.
CROSSOVER
CONFIGURATION
The
24
dB
per
octave crossover can
be
adjusted so this
amplifier
can function as:
1.
Full range
2.
Low Pass
for
a subwoofer.
3.
Band Pass
for
a
subwoofer
or
midbass of a 3 way speaker.v
4.
High Pass
for
a midbass, midrange
or
tweeter.
• The
amplifier
can
be
used
full
range
with
switch in
HP
position and frequency set to
10Hz.
HP is always on so
it
can be used as a subsonic filter.
HP
X1
frequency range is
10Hz
to 400Hz.
HP
X1
0 frequency range is
100Hz
to 4000Hz.
LP:
Adjustment
range is
30
Hz
to 350 Hz.
Band Pass with switch in LP position and adjusting both HP and LP to desired frequency.
• The remote volume
control
is always active.
There is a clip distortion
light
on
the remote volume control.
If you see
this
light
on, reduce volume
until
the light goes out
so
that
you
do not damage your speaker.
• Phase is continuously adjustable between 0 degrees and 180 degrees. Adjust
by
measuring frequency response
at the crossover frequency. Frequency response should
be
as smooth as possible.
•
40Hz
EQ
is adjustable between
OdB
and +6dB.
Measure the subwoofer frequency response and adjust
EQ
to get the smoothest frequency response.
Avoid excess
EQ
boost because
this
will
mak
e the subwoofer sound
"muddy"
a
nd
cause the am
plifier
have clip
distortion prematurely.
AUTOMATIC
POWER
TURN
ON/OFF
1.
Th
e best way to
automatically
turn
the
amplifier
power on and off is to use the
REM
wire
from
your
so
ur
ce
radio
connected to the
REM
a
mplifier
termin
al.
2.
If your
original
equipment stereo
or
source radio has a BTL
amplifier
then the
RCA
inputs have
an
auto
turn
on
sensing circuit. When you connect the high level BTL speaker
wires
to the
RCA
input the
REM
wire
is not
necessary.
1

RCA
INPUT,
BOTH
LOW
LEVEL
AND
HIGH
LEVEL.
The
amplifier
LEVEL
control has sufficient adjustment range for both low level and high level input into the
RCA
jacks. A factory source radio that does not have
RCA
output, using the
wires
that are connected to the speakers, can
be
directly connected to the
RCA
jacks when the
amplifier
LEVEL
control is adjusted to
8V.
SETTING
LEVEL
• Set the
amplifier
LEVEL
control to
minimum
before you
turn
on
the
amplifier
for the
first
time
.
• For lowest distortion and lowest noise the
amplifier
LEVEL
should
be
set at the lowest setting
that
yields
sufficient loudness
without
distortion. For lowest noise
your
source radio volume control should
be
near
maximum
that does not cause distortion.
•
To
find the best
amplifier
LEVEL
setting:
With the
amplifier
LEVEL
at
minimum,
slowly increase the source radio volume to around 3/4 without distortion.
Then, slowly
turn
up the
amplifier
LEVEL
control to the
maximum
desired loudness. Listen very carefully and
turn
down the
amplifier
LEVEL
control
if
you hear any distortion.
SETTING
SUBWOOFER
HIGH
PASS
SUBSONIC
FILTER:
• A subwoofer should have a high pass
filter
often called a subsonic filter. The purpose of a subsonic
filter
is to
limit
very low frequencies
that
your subwoofer
can
not play loud enough without damage. Removing subsonic
frequencies can
allow
your subwooferto play louder.
• For a sealed
box
the high pass is typically set between
10
Hz
and
30Hz
to increase power handling capacity.
• For a vented
box
the high pass
filter
must
be
set 5
Hz
lower
than the port tune frequency to prevent woofer
damage.

1.
Measure the voltage at the
amplifier
power
terminal.
It should
be
between
12
and
15
volts.
2.
Measure the voltage at the
amplifier
REM
terminal.
It should
be
between
12
and
15
volts.
3. If you are using BTL high level for automatic
turn
on,
try
connecting a
REM
wire.
4.
Check your power and ground connections to
be
correct
polarity+
and-
and they are tight.
5.
Check battery connections.
6.
Check the fuse
in
the
REM
wire.
7. Check fuse at battery.
8.
Check fuse inside amplifier.
The fuse is inside the
right
end
cap
beside the power
terminals
.
The recommended
ATC
fuse size is two
25
amp.
?
FOCAL
SIGN
IS
FLASHING
1.
Is
the amp very hot?
Wait a few minutes
for
it
to cool down.
You
need to get more fresh cool
air
to the
ampl
ifier.
Do
not cover the
amplifier
or
mount
it
flush into a hole.
2.
If the amp is cold and the Focal sign is flashing, there is an internal fault. The
amplifier
must
then
be
returned
for service.
?
NO
SOUND
1.
Is
the Focal sign
light
off
or
flashing?
2.
Is
the source radio
on
and is there a sound signal coming from the source radio?
3.
Use
an
ohm
meter
and measure the speaker wires for
short
circuit.
4.
Check connections for
small
"wire whisker" that may
be
shorting between
amplifier
terminals
or
speaker
terminals.
5.
Use
an
ohm
meter
and measure the speaker for
short
circuit.
6. Double check your connections
to
the source radio.
7.
Are you using the correct source radio wires and are they plugged into the correct
amplifier
RCA?
8.
Double check your connections
to
the speakers and speaker crossovers.
9.
Check that
all

replaced
with
a refurbished
amplifier. The
amplifier
will
be
returned to the authorized
retailer
when repairs are complete,
so
