AudioControl LC-4.800 User Manual

5
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 amplier has built-in diagnostic codes to
tell you exactly what is going wrong should the amplier detect a
problem. See specications page 11 for a list of diagnostic codes.
12. GTO Signal Sense – In the ON position, the LC-4.800 amplier will
turn on gracefully when it detects an incoming audio signal, 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.
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 – Ampliers 1 and 2 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum). Similarly for
ampliers 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 fulll 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
amplier gain for channels 1/2 and 3/4 has been maximized for
optimum performance.
