AudioControl AC-LC1i 2 Channel Active Line Output Converter and Line Driver

$219

Product features

The AudioControl AC-LC1i is a two channel active line output converter and line driver that turns factory speaker level signals into preamp outputs for an aftermarket amplifier.

Many factory radios since about 2007 run Class D outputs that shut down or distort if they cannot see a speaker load, which makes tapping them for an amplifier tricky. The LC1i has a load selection switch of 20 ohms, 60 ohms or 20k ohms to keep the factory system happy, and three turn on modes for radios that will not trigger an amplifier the usual way.

What it does

  • Two channels of speaker level input handling up to 40V, or 400W at the 20k ohm setting
  • Two channels of line level input, so it can stay as a line driver after a head unit upgrade
  • Selectable input load: 20 ohms, 60 ohms or 20k ohms
  • Turn on by GTO signal sense, audio sense or a 12V remote input
  • Ground isolation switch to help kill noise
  • Output gain of plus or minus 12dB, up to 9.5V RMS

Fitment and what comes in the box

It suits most factory head units and factory amplifiers when you want to add an amplifier for a sub or speakers. Vehicles with a fibre optic or digital factory amplifier may need a DSP interface instead, so tell us your vehicle first.

AudioControl lists these in the LC1i box:

  • LC1i
  • Speaker and power connectors
  • Manual
  • Warranty card

Installation notes

Wiring, a fuse holder and mounting hardware are not part of the box, and AudioControl recommends a 1A fuse. The 12V remote out is live whenever the unit is on, which can trigger the amplifier.

Warranty

This comes with the manufacturer's warranty through the Australian distributor. See the manufacturer's terms for details, plus our guarantees under the Australian Consumer Law.

We integrate amplifiers with factory systems every week at Albion Park Rail (02) 4257 2636 and South Nowra (02) 4423 5254.

Frequently asked questions

Will the AC-LC1i work with my factory system?

It handles most analogue speaker outputs up to 40V. Tell us the make, model and year, and whether there is a branded factory amplifier, and we will check.

What is the load selection switch for?

Some factory amplifiers need to see a speaker load. Setting 20 ohms or 60 ohms makes the LC1i look like a speaker to them.

How does it turn the amplifier on?

By sensing the DC offset (GTO), by sensing audio, or from a 12V remote wire, and it then sends 12V out to the amplifier.

Does it have bass control?

No. For bass restoration and a sub level remote, look at the LC2i models.
