INSTALLATION GUIDELINES

1. Ensure the +12V lead is disconnected from the
battery before you connect any new equipment.

2. Ensure the mounting location will not interfere
with the gas tank or electrical wiring.

3. Ensure the Amplifier is securely fastened to the
vessel to prevent injury in the event of an accident.

4. Ensure all wiring is protected to avoid pinching
or crushing which could result in damage to the
audio system.

+12V CONNECTION

FUSION amplifiers should be connected directly to the
+12V battery terminal with an inline fuse or circuit
breaker as close the battery as possible.

GROUND CONNECTION

When grounding/earthing your amplifier ensure that the
location is a good source of ground. Make sure the metal
is clean of paint etc as a poor earth could damage your
audio system.

REMOTE TURN-ON CONNECTION

This connection turns the amplifier on & should be
connected to the remote turn on wire from the Head
Unit. If one is not available a switched 12v source must
be used.

RCA INPUTS

Choose the correct length RCA cable & run them to the
RCA outputs of the source/head unit, avoiding running
beside other looms & or power cable.

5. Ensure the mounting location has sufficient
air flow around the amplifier. If the amplifier is
mounted in an enclosed space a 3” fan with
ducting should be used to aid in air flow.

6. Do not mount any amplifier on a subwoofer
enclosure as extended exposure to vibration may
cause malfunction of the amplifier.

7. Ensure you use the recommended gauge wire/
cable for all amplifier connections.

WIRING

Ensure the audio system is turned off before making any
connections to the amplifier, speakers or source unit,
failure to do so could result in permanent damage to the
audio system.

When wiring the FUSION amplifier ensure that the cable
is protected from sharp objects and always use rubber
grommets when wiring through metal panels.

Ensure all terminals and connections are protected from
the vessel chassis and from each other as failure to do so
could result in permanent damage to the audio system.

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

2. Turn the volume of the head unit to and the bass
and treble to zero

3. Adjust the level control until the desired maximum
volume is achieved without distortion.

4. Failure to follow these steps may cause permanent
damage to the audio system.

CONTROL DESCRIPTIONS

1

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 MS-DA51600 2 x
40A fuses.

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.

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.

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

2 3 4 5 6 7 8 9 10

11

12

13

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:

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.

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.
