1. SPEAKER OUTPUT:
Connect your speakers to these terminals.
2. FRONT RCA INPUT:
Connect these RCA connectors to a head unit with a front low
level output connection.
3. REAR RCA INPUT:
Connect these RCA connectors to a head unit with a rear low
level output connection.
4. SUBWOOFER RCA INPUT:
Connect these RCA connectors to a head unit with a
subwoofer low level output connection.
5. REMOTE LEVEL CONTROL CONNECTION:
Connect the optional (supplied) Remote Level Controller to
this socket.
6. POWER AND STATUS LED’S:
This displays “green” if the amplier has been correctly
powered up and ‘red’ if any faults are present.
7. FUSES:
Please ensure the correct type of fuse is tted. For CA-
DA51600 2 x 40A fuses.
8. +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.
9. REMOTE TURN-ON CONNECTION:
This terminal is for turning the amplier on & off. The remote
input requires a switched positive (+12V) to power ‘ON’ the
amplier. 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.
10. GROUND CONNECTION:
Connect directly to the vehicle’s chassis via a 4 guage power
cable. NOTE: This is the rst wire to connect up during the
installation.
11. SUBWOOFER LP FILTER FREQUENCY:
This sets the crossover frequency point for the subwoofer
channels’ low pass lter between 32Hz and 320Hz.
12. REAR LEVEL:
This allows level adjustment of the rear input signal. Use this
control to directly match the head unit to the amplier. To
set this control correctly, turn the amplier 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.
13. FRONT LEVEL:
This allows level adjustment of the front input signal. Use this
control to directly match the head unit to the amplier. To
set this control correctly, turn the amplier 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.
14. FUSION LOW FREQUENCY CONTROL:
The FUSION Low Frequency Control (F.L.F.C.) is a dual stage
control interface. The combination of a Subsonic lter & a
Bass Boost control allows precise shaping of the audio signal
for your subwoofer(s). The Subsonic lter is essentially a
high-pass crossover which blocks the frequency signal
from 10Hz - 80Hz. This signal often contains no music & 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.
15. SUBWOOFER AUDIO SOURCE:
This switch selects the audio source for the subwoofer
channel. Audio can be sourced from the SUB input
RCA connectors or from the FRONT & REAR input RCA
connectors.
16. SUBWOOFER LEVEL:
This allows level adjustment of the subwoofer input signal.
Use this control to directly match the head unit to the
amplier. To set this control correctly, turn the amplier level
to MIN & 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.
17. REAR FILTER FREQUENCY:
This sets the crossover frequency point for the rear lter
between 32Hz and 320Hz. NOTE: Failure to correctly set
could result in speaker damage.
18. REAR FILTER SELECTION:
This switch selects the type of lter used for the rear audio
signal. Either Low Pass, High Pass or Full Range can be
selected. The Low Pass lter is designed to lter out all mid
to high frequencies that only full range speakers should
produce. The High Pass lter is designed to lter out all
low frequencies that only subwoofers should produce. Full
Range allows all frquencies.
19. FRONT FILTER SELECTION:
This switch selects the type of lter used for the rear audio
signal. Either Low Pass, High Pass or Full Range can be
selected. The Low Pass lter is designed to lter out all mid
to high frequencies that only full range speakers should
produce. The High Pass lter is designed to lter out all
low frequencies that only subwoofers should produce. Full
Range allows all frquencies.
20. FRONT FILTER FREQUENCY:
This sets the crossover frequency point for the rear lter
between 32Hz and 320Hz. NOTE: Failure to correctly set
could result in speaker damage.
