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.

About the AudioControl LC8i
From our tech experts at CEN
A line output converter, 8 channel, taking speaker-level signal from a factory system and producing a clean line-level signal for an amplifier.
Who it suits
Drivers adding an amplifier or subwoofer while keeping the factory head unit, which is most modern cars where the stereo is built into the dashboard.
Our tech experts advise
Factory outputs vary: some are already amplified, some are equalised in ways that need correcting at the source. We check what your vehicle actually outputs before specifying. get in touch. See car audio installation.

Frequently Asked Questions
Q: How many channels does the AudioControl LC8i have?
A: The LC8i has four pairs of speaker-level inputs (8 channels) and four pairs of RCA pre-amp outputs (8 channels). It can sum 4, 6 or 8 input channels into a full-range pre-amp signal.
Q: How much power can the LC8i speaker inputs handle?
A: Each speaker-level input handles up to 400 watts per channel at 4 ohms, so it suits most factory and amplified factory systems.
Q: Does the LC8i have an auxiliary input and remote?
A: Yes. It has a pair of RCA auxiliary inputs for a second source. The included ACR-3 wired remote selects the source, sets the auxiliary volume and controls the channel 4 or subwoofer output level.
Q: Will the LC8i switch my amplifiers on automatically?
A: Yes. Signal-sensing auto turn-on powers the unit up when a speaker-level signal is present, and its +12V remote output (up to 1 amp) turns your amplifiers on whenever the LC8i is on.
Q: Can CEN fit this for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
