Product Spotlight: AudioControl LC2i

AudioControl LC2iYears ago, car audio specialist retailers were a destination for the latest in source unit technology. Bluetooth, MP3 and WMA playback via USB and GPS-based navigation brought clients in to upgrade their factory radios. In the past few years, these features and more have become standard in many factory infotainment systems. What are car audio retailers doing to keep busy? They are offering audio solutions that improve the sound quality of the rest of these systems. A company that has always been a leader in integration with factory source units is AudioControl in Seattle, Washington. The AudioControl LC2i two-channel line converter is a staple in the industry for OEM integration.

Purpose and Performance

AudioControl LC2iAudio integration begins with an accurate and reliable way to connect the audio outputs of a factory source unit or infotainment system to an aftermarket amplifier or processor. In some vehicles, this is a relatively easy task; in others, it is difficult. The AudioControl LC2i is a two-channel integration processor: It will take two channels of amplified signal and process it down to a signal suitable for connection to an amplifier. Many call this a line-output converter, but the LC2i is much more.

The LC2i can accept input signals from amplifiers as powerful as 400 watts. That works out to 40 volts of signal, enough for applications like the notorious BMW subwoofer amplifiers. The output from the LC2i can be adjusted to as high as 9.5 volts, and it has an output impedance of 150 ohms.

Additional Features

One challenge that installation technicians experience is to find a way to turn on an aftermarket amplifier. Very few factory source units feature an amp turn-on signal, and those that do often transmit this signal over the CAN bus. The LC2i includes a feature called GTO™ – Great Turn On. As soon as you turn on the radio, the LC2i will wake up and send a signal your amplifier or processor to turn it on. The GTO function is on by default, but can be defeated if you are using the LC2i as a line-driver with an aftermarket head unit with low-voltage preamp outputs.

AudioControl LC2iIt should be no surprise that many source units have limited bass output. The speakers used in most factory audio systems are, at best, wimpy and anemic. To manage this, head units often limit the amount of bass they produce. Some factory radios reduce bass output as the volume increases. The LC2i has a feature called AccuBASS to compensate for this. AccuBASS will boost bass frequencies beyond an adjustable threshold to restore warmth and impact to your aftermarket speakers and subwoofers. Your installer can adjust when the bass boost starts working and the amount of boost that it adds.

Who doesn’t like switches, buttons and knobs? We most certainly do! The LC2i has a second preamp output controlled by an optional remote control. The Dash Remote can be mounted under the dash with its included bracket, or disassembled and integrated with your dash or console for a seamless look. The remote will adjust the output signal from -19 to 0 dB so prevent confusing or complicating the gain structure of the system. If you are adding a dedicated subwoofer amplifier to your system, then the Dash Remote is a great idea.
