The AudioControl LC8i is an 8-channel active line output converter, taking speaker-level outputs from almost any factory head unit and converting them to clean RCA pre-amp signals of up to 8.5V RMS. It is part of AudioControl's LC-series line out converter range.

This listing is the 8-channel LC8i. The AudioControl LC-series is also available as the LC7i 6-channel, the LC6i 6-channel, and the LC2i 2-channel.

LC8i: 8-Channel Line Out Converter with Auxiliary Input

The LC8i is designed for drivers who want to add aftermarket amplifiers to a factory stereo without replacing the head unit. It accepts speaker-level signals from virtually any factory system and outputs clean, high-voltage RCA signals ready for an aftermarket amplifier. Channel summing, an auxiliary input and a wired remote are all included.

Features

• Speaker input: Four pairs of inputs handle up to 400W per channel, compatible with most factory stereo systems.
• Channel summing: Combines 4, 6 or 8 input channels into a full-range pre-amp signal with no additional cables or hardware required.
• AutoMode inputs: Channel 3 input automatically feeds channels 3 and 4 outputs when no signal is present at the channel 4 input.
• Auxiliary input: A pair of RCA auxiliary input jacks connects secondary sources such as a phone or satellite radio, switched using the wired remote.
• Output level: ±12dB adjustment per RCA output to match speaker-level input levels. Separate output level control for the auxiliary input.
• Auto turn-on: Signal-sensing circuit switches the unit on when a speaker-level signal is detected and off when it disappears.
• Remote output: +12V DC remote output triggers a connected amplifier to power on, with a maximum current output of 1A.
• Wired remote: Allows source selection, auxiliary input volume adjustment and output level control for channel 4/subwoofer.
• Ground isolation: Switchable power supply ground eliminates ground loop noise.
• Terminal blocks: Removable terminal blocks for power, ground, remote and speaker-level connections, accepting wire up to 12 gauge.
