5. REMOTE SUBWOOFER 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 SG-
DA51600 2 x 40A fuses.
8. +12V CONNECTION:
Connect directly to the vessel battery positive (+)
terminal via a 4 gauge 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
gauge 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. ZONE 2 LEVEL:
This allows level adjustment of the zone 2 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 tone settings 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. ZONE 1 LEVEL:
This allows level adjustment of the zone 1 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
tone settingson 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 Zone 1 & Zone 2 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 tone settings 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. ZONE 2 FILTER FREQUENCY:
This sets the crossover frequency point for the zone
2 filter between 32Hz and 320Hz. NOTE: Failure to
correctly set could result in speaker damage.
18. ZONE 2 FILTER SELECTION:
This switch selects the type of filter used for the zone 2
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. ZONE 1 FILTER SELECTION:
This switch selects the type of filter used for the zone 1
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. ZONE 1 FILTER FREQUENCY:
This sets the crossover frequency point for the zone
1 filter between 32Hz and 320Hz. NOTE: Failure to
correctly set could result in speaker damage.
