LEVEL CONTROL
This control is used to match the input level of the amplifier to the output level of you head unit. We recommend
the following method. NOTE: Remove screws and the top cover of amplifier to access controls.
1.
2.
Turn the amplifier level to zero
3.
Adjust the level control until the desired
maximum volume is achieved without
distortion.
Turn the volume of the head unit to ¾ and the
bass and treble to zero
4.
Failure to follow these steps may cause
permanent damage to the audio system.

1. SPEAKER OUTPUT:
Connect your subwoofer(s) to these terminals.
9. GROUND CONNECTION:
Connect directly to the vehicle’s chassis via a 4 guage power
cable. NOTE: This is the first wire to connect up during the
installation.
NOTE: The positive (+) and negative (-) are internally linked.
2. REMOTE LEVEL CONTROL CONNECTION:
Connect the optional (supplied) Remote Level Controller to
this socket.
10. LEVEL CONTROL:
This allows level adjustment of the input signal. Use this
control to directly match the head unit to the amplifier. To
set this control correctly, turn the amplifier level to MIN and
the head unit to 3/4 volume, with the bass and treble on zero,
then slowly turn up the level control towards the MAX end of
the control. NOTE: If the sound becomes distorted, turn this
control down.
3. RCA INPUT:
Connect these RCA connectors to a head unit with a low level
output connection.
4. RCA OUTPUT:
Use these RCA connectors to connect to
a
secondary
amplifier. This output is a pass-thru connection derived
from the RCA input connectors so that the signal level and
frequency response is the same as the original input signal.
11. SUBWOOFER LP FILTER FREQUENCY:
This sets the crossover frequency point for the subwoofer
channels’ low pass filter between 32Hz and 320Hz.
5. POWER AND STATUS LED’S:
12. FUSION LOW FREQUENCY CONTROL:
This displays “green” if the amplifier has been correctly
powered up & ‘red’ if any faults are present.
The FUSION Low Frequency Control (F.L.F.C.) is a dual stage
control interface. The combination of a Subsonic filter and a
Bass Boost control allows precise shaping of the audio signal
for your subwoofer(s). The Subsonic filter is essentially a
high-pass crossover which blocks the frequency signal from
10Hz - 80Hz. This signal often contains no music and its
removal will improve subwoofer control. The Bass Boost is a
variable control to increase the level at 45Hz from 0 - +12dB
of gain. Adjust these controls with extreme care.
6. FUSES:
Please ensure the correct type of fuse is fitted. For CA-
DA12250 3 x 40A fuses.
7. +12V CONNECTION:
Connect directly to the vehicle battery positive (+) terminal via
a 4 gauge power cable, with an inline fuse or circuit breaker
at the battery end. NOTE: This is the last wire to connect up
during installation. Damage could result if this is not done.
8. REMOTE TURN-ON CONNECTION:
This terminal is for turning the amplifier on and off. The
remote input requires a switched positive (+12V) to power
‘ON’ the amplifier. This can usually be found on the rear of
the head unit in the form of a remote output. If not available
you can wire to the ACC position on the ignition key.

12. FRONT LEVEL:
This allows level adjustment of the rear input signal. Use this
control to directly match the head unit to the amplifier. To
set this control correctly, turn the amplifier level to MIN and
the head unit to 3/4 volume, with the bass and treble on zero,
then slowly turn up the level control towards the MAX end of
the control. NOTE: If the sound becomes distorted, turn this
control down.
3. REAR RCA INPUT:
Connect these RCA connectors to a head unit with a rear low
level output connection.
4. FRONT RCA INPUT:
Connect these RCA connectors to a head unit with a front low
level output connection.
13. REAR FILTER FREQUENCY:
This sets the crossover frequency point for the rear filter
between 32Hz and 320Hz. NOTE: Failure to correctly set
could result in speaker damage.
5. POWER AND STATUS LED’S:
This displays “green” if the amplifier has been correctly
powered up & ‘red’ if any faults are present.
14. REAR FILTER SELECTION:
6. FUSES:
This switch selects the type of filter used for the rear audio
signal. Either Low Pass, High Pass or Full Range can be
selected. The Low Pass filter is designed to filter out all mid
to high frequencies that only full range speakers should
produce. The High Pass filter is designed to filter out all
low frequencies that only subwoofers should produce. Full
Range allows all frquencies.
Please ensure the correct type of fuse is fitted.
For CA-DA41400 2 x 40A fuses.
7. +12V CONNECTION:
Connect directly to the vehicle battery positive (+) terminal via
a 4 gauge power cable, with an inline fuse or circuit breaker
at the battery end. NOTE: This is the last wire to connect up
during installation. Damage could result if this is not done.
15. FRONT FILTER SELECTION:
This switch selects the type of filter used for the rear audio
signal. Either Low Pass, High Pass or Full Range can be

installation.
This sets the crossover frequency point for the rear filter
between 32Hz and 320Hz. NOTE: Failure to correctly set
could result in speaker damage.
10. REAR LEVEL:
This allows level adjustment of the front input signal. Use this
control to directly match the head unit to the amplifier. To
set this control correctly, turn the amplifier level to MIN and
the head unit to 3/4 volume, with the bass and treble on zero,
then slowly turn up the level control towards the MAX end of
the control. NOTE: If the sound becomes distorted, turn this
control down.
