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. Turn the amplifier level to zero
3. Adjust the level control until the desired maximum
volume is achieved without distortion.
2. Turn the volume of the head unit to and the bass
and treble to zero
4. Failure to follow these steps may cause permanent
damage to the audio system.

TROUBLE SHOOTING
Problem
Possible Reason
Solution
Amplifier not switching
on. Power LED not ‘on’.
No +12v to power wire
No power to remote wire

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 MS-DA51600 2 x
40A fuses.
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.
8. +12V CONNECTION:
Connect directly to the vessel 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.
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.
10. GROUND CONNECTION:
Connect directly to the vessel’s earth system 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.
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.
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.
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.
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.
19. FRONT FILTER SELECTION:
This switch selects the type of filter used for the front 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.
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
20. FRONT FILTER FREQUENCY:
This sets the crossover frequency point for the front filter between 32Hz
and 320Hz. NOTE: Failure to correctly set could result in speaker
damage.

SERIES AND PARALLEL SUBWOOFER WIRING FOR
DUAL VOICE COIL SUBWOOFERS
PARALLEL VOICE COIL WIRING (2 OHM OPERATION)
To wire a 4 Ohm DVC subwoofer in parallel to get 2 Ohm, use two short pieces of speaker wire and link the positive
from one coil to the positive of the second coil, and do the same for the negative as shown below. Then wire the
amplifier to opposite sides of the subwoofer in order to equalise any connection resistance.
