AudioControl LC-1.800 800W High-Power Mono Subwoofer Amplifier with AccuBass®

AudioControl LC-1.800 800W High-Power Mono Subwoofer Amplifier with AccuBass®

When you demand the perfect blend of power and performance, AudioControl provides answers and the LC-1.800 is no exception.

No matter the install, you can be assured power will meet and exceed expectations with 800 watts at 2 ohms. The mix of high level and low level inputs mean you have the widest input voltage range in the industry. AudioControl’s patented AccuBASS® circuit is the only way to properly overcome factory bass roll-off and heavily equalized factory bass settings.

Enjoy loud, clean and articulate bass combined with the best warranty available with the LC-1.800 amplifier.

All features at a glance

• GTO Signal Sense

  Many cars can turn on the factory amplifier even if the source unit is off (Alarms, Cell phones, etc). To prevent this from turning your system on unexpectedly, you can bypass the GTO™ circuit by moving the GTO™ jumper, and using an applied 12-volts at the Remote In terminal. Using the jumper may result in some factory features not working fully.

• AccuBASS® Processing

  Factory installed amplifiers and woofers are (unfortunately) not designed to reproduce bass at high volumes. Car manufacturers adapt to this by taking the bass out of the signal when you turn up the volume. AudioControl developed the patent pending AccuBASS™ circuit to restore bass. After a quick and easy one-time setting, the AccuBASS™ circuit takes over the bass just as the factory system rolls off. You get smooth, seamless, and rock solid bass response regardless of volume level.

• 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 on input 1 and 2 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 signals 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-1.800.

• Remote Power Input Terminal

  This screw terminal connects to the 12V remote trigger output of some head units. When the head unit is turned on, then the LC-1.800 amplifier will turn on. Alternatively, you can use the GTO feature of the amplifier so it will turn on when an audio signal is detected at the speaker-level or line-level inputs.

• RCA Analog Line-Level Inputs

  The line-level output from the head unit or factory installed radios can connect here, so the LC-1.800 will receive the line-level audio signals. The left and right signals are summed internally to produce a mono subwoofer signal. Do not use the speaker-level inputs if you are using the RCA line-level inputs.

• Speaker-Level Inputs

  The LC-1.800 amplifier is supplied with a standard 4-conductor plug that allows for easy installation and removal. The speaker-level output from amplifiers and factory installed radios can connect here, so the LC-1.800 will receive the audio signals and do its subwoofer thing. The left and right audio signals are summed internally to produce a mono subwoofer signal. Make sure that you follow the plus and minus polarity markings on the LC-1.800 and match it to the polarity of the speaker wiring. Do not use the RCA Line-level inputs if you are using the speaker-level inputs.

• Crossover Frequency

  Since component speakers (like woofers) are designed to reproduce certain frequency ranges, a crossover allows you to match the speaker to the appropriate frequency range. Most manufactures list a recommended crossover frequency as part of the speaker specifications. Choosing the correct crossover point will provide increased speaker reliability and optimum sound quality. The LC-1.800 amplifier comes with an adjustable-frequency 24/dB Octave Linkwitz-Riley crossover. Adjust the crossover frequency on the LC-1.800 amplifier to match the value specified by your subwoofer’s manufacturer. If you do not know this value, start out with the crossover selector turned all the way to the left (counter clockwise) and adjust it until you find a position that suits your subwoofer system best.

• Remote Level Control ACR-1 (Optional)

  The optional AudioControl ACR-1 dash control is a remote level control for your LC-1.800 amplifier. It may be mounted under the dash using its own enclosure, or through a custom hole in the dash. The level control knob should be within reach of the driver, and in a spot where the LED is plainly visible.
