CA-DA51600 - CONTROL DESCRIPTIONS

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 amplifier has been correctly

powered up and ‘red’ if any faults are present.
7. FUSES:

Please ensure the correct type of fuse is fitted. 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 amplifier on & 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.
10. 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.
11. SUBWOOFER LP FILTER FREQUENCY:

This sets the crossover frequency point for the subwoofer

channels’ low pass filter 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 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.
13. FRONT 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.
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 filter & 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 & 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

amplifier. To set this control correctly, turn the amplifier 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 filter

between 32Hz and 320Hz. NOTE: Failure to correctly set

could result in speaker damage.
18. REAR 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

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.
19. FRONT FILTER SELECTION:
