Product Description

AudioControl LC1i

The LC1i joins ranks with AudioControl’s most popular active line output converter, the LC2i. Adding a sub? Planning a full system? Either way, get the best possible signal from your factory sound system to your amplifiers. Load selection switches mean Original Equipment integration has never been easier and the LC1 will work with the most finicky factory sound systems. Installer friendly turn on trigger modes allow for flexibility via GTO Signal Sense (DC offset), audio sense, or remote 12 volt inputs. For future head unit upgrades, the LC1i is also a line driver and can remain in the system to provide optimal preamp signal.

Provide input signal for your amp. Aftermarket amplifiers and DSP sound processors need clean and strong input signals, whether they come from a receiver's RCA outputs or a factory amp's speaker outputs. AudioControl's LC1i line output converter can produce up to 9.5 volts of preamp-level output in either case, acting as a line driver using its RCA inputs or as a line output converter using the speaker-level inputs.

Works with factory amps. Those speaker-level inputs can handle up to 40 volts, the equivalent of 400 watts, so you can use one in a premium system with a factory amplifier, enabling you to retain all your vehicle's factory audio options and warnings. The LC1i's level control with a Maximized LED indicator help you to keep the signal strong, as well as under control and distortion-free.

AudioControl LC1i

GTO Signal Sense

DC offset is a highfalutin technical term that means the LC1i can sense when the head unit is on, not necessarily when audio is being sent to the LC1i. Use GTO Signal Sense mode when your factory sound system outputs a DC offset when it is on.

AudioControl LC1i

Setting Levels

Use the Output Level knob to adjust the output level. We would say more here, but it doesn’t get much simpler than that.

AudioControl LC1i

Audio Sense

When this mode is selected, the LC1i will ONLY turn on when you start playing a source from the head unit. Whether it be the radio, CD player or streaming via Bluetooth from a mobile device. If you turn the head unit on, but DON’T play audio, the LC1i will not turn on.

AudioControl LC1i

Remote Input

This is the traditional way to turn on the LC1i and gives you more control of exactly when the unit will turn on. Most common places to connect the remote input are from the ignition of the vehicle, fuse box, or some other 12V source (such as a cigarette lighter).

AudioControl LC1i

Ground Isolation Switch

This handy switch allows the user to change how the LC1i is grounded. Sometimes when installing car audio equipment, “ground buzz” or “alternator whine” will creep into the audio path, wreaking havoc on your listening experience. There are 3 positions. GND, ISO, and 200 ohms. The unit ships from the factory in the ISO position.

GND - Power ground and audio ground are tied together.

ISO - Power ground and audio ground are separate.

200Ω - There is 200 ohms of resistance between power ground and audio ground.

AudioControl LC1i

Load Selection Switch

The LC1i is designed to present NO load to the output of the factory amp, which can make some factory amps upset and may stop passing audio. The Load Selection feature tricks the factory amp in to detecting a speaker load so it will continue to pass audio.

20 Ω - Best suited for late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles equipped with Original Equipment base sound system. (no separate factory amplifier)

60 Ω - Best suited for late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles equipped with a separately amplified Original Equipment “premium” sound system.

20 kΩ - Best suited for all other applications

AudioControl LC1i

Power

As awesome as it is that the LC1i can be turned on 3 different ways, you still very much need to connect the LC1i to constant +12V power and ground. Maybe one day science will invent a way to electrically power devices via the sweet guitar solo of Jimi Hendrix, but until then, we need +12V power and ground

Remote Output

Use the Remote Output (Rmt/Out) to trigger on your aftermarket amplifier. When the LC1i turns on (regardless of method) the Remote Output will always be active. Do not connect more than two amplifiers to the LC1i Remote Output. Connecting more than two amplifiers may damage the LC1i.

AudioControl LC1i

Maximized Light

The Maximized Light can be used to help achieve optimal output level and will let you know if you are getting close to clipping the output of the LC1i.

With the factory system set to its maximum undistorted volume, match the output level of the LC1i to the input maximum of your after market amplifier. If the Maximized Light turns on, the LC1i output is distorting. Turn the output level down until the Maximized Light turns off. IF THE MAXIMIZED LIGHT NEVER TURNS ON, don’t panic. This just means the output of the LC1i is not clipping/distorting.
