FEATURES:

• Overview :  The AudioControl LC-1.800 mono subwoofer amplifier is designed to enhance the sound of your car stereo system, whether it's a factory or an aftermarket one. Outputting 500 watts @ 4 ohms and 800 watts @ 2 ohms, the LC-1.800 can accept both line and speaker level inputs. Key features include AudioControl's AccuBass compensation circuit, GTO signal sensing turn-on, and a connection port for the optional ACR-1 remote level control (sold separately).  The amplifier features a black brushed aluminum chassis, with black powder-coated cast alloy heat sinks and a one piece bottom panel. A black brushed aluminum cover is provided to protect the amp controls from tampering. The included 2.5mm Allen key is used to remove the cover.

• AccuBASS :  The patented AccuBASS processing circuit compensates for factory bass rolloff to improve bass performance, especially with most factory installed sound systems. The circuit has two rotary controls: the Threshold lets you dial in the level at which the AccuBASS will begin to work, while the Level control raises or lowers the level of AccuBASS compensation. A slide switch allows the AccuBass feature to quickly be Enabled or Disabled.

• ACR-1 Remote :  The optional AudioControl ACR-1 wired remote lets you adjust the subwoofer output level from the driver's seat. The remote level control comes with a 20' cable, terminating in an RJ-14 jack that plugs into the amp, and is designed to be mounted under a dash for easy access while driving.

• Maximum Input Level Control (MILC) :  The amplifier analyzes the input signal to detect any clipping. If the signal reaches the level of clipping, the MILC Source Clip LED glows red, prompting you to turn down the gain level. When the gain level is maximized, a green Maximized LED will glow to indicate the gain, for that set of channels, is set to the optimum level.

• GTO (Great Turn On) Signal Sense :  If you are connecting the amplifier to a factory stereo or an aftermarket unit without a remote turn-on lead, the GTO Signal Sense circuitry can turn on the amplifier when an audio signal is detected on either the line-level or speaker-level inputs. After a period of time with no signal input, the amp will turn itself off. An On/Off slide-switch is provided on the amp activate the GTO Signal Sense feature.

• Controls :  The LC-1.8200's controls are located under a protective panel that can easily be removed with the included 2.5mm Allen key. A flat-head screwdriver (not included) is needed to adjust the rotary controls which include the AccuBass and GTO settings, a Low-Pass crossover with a range from 30 Hz to 230 Hz, a Polarity switch with 0 or 180, and LED indicators for Power and Protection.
