1. SPEAKER OUTPUT:
Connect your subwoofer(s) to these terminals.
NOTE: The positive (+) and negative (-) are internally linked.
2. REMOTE LEVEL CONTROL CONNECTION:
Connect the optional (supplied) Remote Level Controller to
this socket.
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.
5. POWER AND STATUS LED’S:
This displays “green” if the amplifier has been correctly
powered up & ‘red’ if any faults are present.
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.
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.
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.
11. SUBWOOFER LP FILTER FREQUENCY:
This sets the crossover frequency point for the subwoofer
channels’ low pass filter between 32Hz and 320Hz.
12. FUSION LOW FREQUENCY CONTROL:
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.
