CA-DA41400 - CONTROL DESCRIPTIONS

1. SPEAKER OUTPUT:

Connect your speakers to these terminals.
2. 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.
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.
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-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.
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. 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.

11. BASS BOOST:

The Bass Boost is a variable control to increase the level at

45Hz from 0 - +12dB of gain. Adjust this control with extreme

care.
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.
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.
14. 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.
15. FRONT FILTER SELECTION:
