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 specifications page 11 for a list of diagnostic codes.
12. GTO Signal Sense – In the ON position, the LC-4.800 amplifier will
turn on gracefully when it detects an incoming audio signal, 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. If enabled, ACR-1 controls the
level of the level of the main 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 main outputs and line outputs.
15. HP Crossover Frequency – Selects the 30 Hz to 300 Hz crossover
point to match your speakers and system. The crossover for chan-
nels 1/2 is high-pass only; the crossover for channels 3/4 can be
selected as high-pass or low-pass.
16. Mono/Stereo – Amplifiers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum). Similarly for
amplifiers 3 and 4. For example, 1/2 can be stereo, 3/4 mono.
17. Gain Control – Adjusts the overall output levels.
18. AccuBASS® Threshold – Selects the level at which the AccuBASS®
will begin to work.
19. AccuBASS® Level – Adjusts the level of the AccuBASS®.
20. Front/Rear Bus Sum – This sums the front and rear inputs togeth-
er. So two inputs (L/R) can feed four outputs (2L/2R).
21. Crossover Type LP/HP – The crossover of channels 3/4 can be
selected as a high-pass or low-pass type. Super for bi-amping your
speakers, with channels 1/2 high pass, and channels 3/4 low pass.
22. MILC™ Source Clip LED – The MILC™ (Maximum Input Level
Control) patent-pending level-setting circuit prevents clipping
and damaging distortion. It calculates when the waveform of an
incoming audio signal is clipping, and if it is, this LED will fulfill its
prime objective and shine forth.
With this advanced feature, you are able to optimize the level of
the incoming audio signal until the Source Clip LED is just-prior
to lighting. If the LED comes on during normal operation, you
should adjust the level of the audio signals before they reach the
LC-4.800.
23. Gain Maximized LEDs – These LEDs indicate when the LC-4.800
amplifier gain for channels 1/2 and 3/4 has been maximized for
optimum performance.
