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 amplier. To set this control correctly, turn the
amplier 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 lter 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 lter used for the zone 2
audio signal. Either Low Pass, High Pass or Full Range can
be selected. The Low Pass lter is designed to lter out
all mid to high frequencies that only full range speakers
should produce. The High Pass lter is designed to lter
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 lter used for the zone 1
audio signal. Either Low Pass, High Pass or Full Range can
be selected. The Low Pass lter is designed to lter out
all mid to high frequencies that only full range speakers
should produce. The High Pass lter is designed to lter
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 lter between 32Hz and 320Hz. NOTE: Failure to
correctly set could result in speaker damage.
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 amplier has been correctly
powered up and ‘red’ if any faults are present.
7. FUSES:
Please ensure the correct type of fuse is tted. 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 amplier on & off. The
remote input requires a switched positive (+12V) to
power ‘ON’ the amplier. 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 rst wire to connect up
during the installation.
11. SUBWOOFER LP FILTER FREQUENCY:
This sets the crossover frequency point for the subwoofer
channels’ low pass lter 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
amplier. To set this control correctly, turn the amplier
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
amplier. To set this control correctly, turn the amplier
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
lter & a Bass Boost control allows precise shaping of
the audio signal for your subwoofer(s). The Subsonic
lter 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.
