10. Power LED
– If you have connected your battery power, vehicle
ground, and turn-on lead (or GTO signal sensing) correctly, then
this light should be green to indicate the power is ON.
11. Protection LED
– The amplifier has built-in diagnostic codes to
tell you exactly what is going wrong should the amplifier detect a
problem. See page 15 for a list of diagnostic codes.
12. GTO Signal Sense
– In the ON position, the LC-6.1200 amplifier
will turn on gracefully when it detects an incoming audio signal
on inputs 1 and 2, and it will turn off after a period of time when
the audio signal fades away to silence. Turn this OFF if using the
remote power terminal (see item 3 above) turn on method.
13. Front High Level
– Adjusts the Front High speaker-level input
levels, to achieve a nice balance in levels.
14. AccuBASS®/ACR-1
– Enables/disables the AccuBASS® circuit and
the ACR-1 remote level control for outputs 1 and 2. If enabled, the
ACR-1 controls the level of the level of the 1 and 2 outputs and
line outputs. If disabled, then it just controls the line outputs (to
a subwoofer for example). The AccuBASS® has its own controls to
work wonders on the lower bass and line outputs.
15. HP Crossover Frequency
– Selects the HP crossover point to
match your speakers and system. Channel 1 and 2 outputs will
receive the frequency range above the frequency selected. Use
the crossover range switch (16) to select the range from 30 to 300
Hz, or from 500 Hz to 5 kHz. The crossover for channels 1/2 is high-
pass only.
16. Crossover Range
– Use this switch to select the range of the HP
crossover frequency control (15) from 30 to 300 Hz, or from 500 Hz
to 5 kHz.
17. Mono/Stereo
– Amplifiers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
18. Gain Control
– Adjusts the overall 1 and 2 output levels.
19. AccuBASS® Threshold
– Selects the level at which the AccuBASS®
will begin to work.
20. AccuBASS® Level
– Adjusts the level of the AccuBASS®.
21. 1/2 and 3/4 Bus Sum
– This sums the 1/2 and 3/4 inputs together.
So two inputs (L/R) can feed four outputs (2L/2R).
22. AccuBASS®/ACR-1
– Enables/disables the AccuBASS® circuit and
the ACR-1 remote level control for outputs 3 and 4. If enabled,
ACR-1 controls the level of the level of the 3 and 4 outputs and
line outputs. If disabled, then it just controls the line outputs (to
a subwoofer for example). The AccuBASS® has its own controls to
work wonders on the lower bass of the outputs and line outputs.
23. HP Crossover Frequency
– Selects the HP crossover point to
match your speakers and system (if the crossover switch (24) is set
to HP). The channel 3/4 outputs will receive the frequency range
above the frequency selected. If the crossover switch is set to
bandpass, then this selects the top frequency of the band.
