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.

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
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.
