9. 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.
10. Protection LED – The amplier has built-in diagnostic codes to
tell you exactly what is going wrong should the amplier detect a
problem. See page 15 for a list of diagnostic codes.
11. GTO Signal Sense – In the ON position, the LC-5.1300 amplier
will turn on gracefully when it detects an incoming audio signal
on inputs 1 and 2, and it will turn o 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.
12. Front High Level – Adjusts the Front High speaker-level input
levels, to achieve a nice balance in levels.
13. 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.
14. 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.
15. Mono/Stereo – Ampliers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
16. Gain Control – Adjusts the overall 1 and 2 output levels.
17. 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).
18. 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.
19. Crossover Type HP/Bandpass – The crossover of channels 3/4
can be selected as a high-pass or bandpass type. For example,
bandpass is super for bi-amping your speakers, with channels 1/2
high pass for tweeters, and channels 3/4 bandpass for mid-range.
20. LP Crossover Frequency – Selects the lower frequency of the
band to match your speakers and system (only if the crossover
type switch (24) is set to bandpass). The channel 3/4 outputs will
receive the frequency range selected by the HP and LP controls.
21. Mono/Stereo – Ampliers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum).
22. Gain Control – Adjusts the overall 3 and 4 output levels.
23. 3/4 and 5/6 Bus Sum – This sums the 3/4 and 5/6 inputs together.
So two inputs (L/R) can feed four outputs (2L/2R).
24. AccuBASS® – Enables/disables the AccuBASS® circuit for output 5.
The AccuBASS® has its own controls to work wonders on the lower
bass of the output.
