Lc7i

The AudioControl LC7i is a 6‑channel active line output converter designed for music lovers who want powerful, high‑quality sound without replacing their factory radio. This OEM integration solution lets you keep your stock head unit while adding aftermarket amplifiers, subwoofers, and speakers for a dramatically improved in‑car audio experience. The LC7i is especially effective at fixing one of the biggest weaknesses in modern factory systems: weak bass.

Built‑In AccuBASS for Strong, Clean Low End
The LC7i features AudioControl’s patented AccuBASS™ circuitry, engineered specifically to correct the bass roll‑off common in many factory stereos. As you turn up the volume, many OEM systems reduce low‑frequency output; AccuBASS automatically restores and maintains bass response, delivering fuller, more dynamic sound at all listening levels.

Factory Integration & System Flexibility
Designed for maximum sound quality and seamless OEM integration, the LC7i line output converter:

• Interfaces with factory radios and factory amplifiers
• Provides six channels of speaker‑level input and six channels of preamp output
• Allows internal channel summing, perfect for vehicles where the factory amp has built‑in crossovers
• Can feed single or multiple aftermarket amplifiers, giving you the flexibility to build anything from a simple sub upgrade to a full multi‑amp system

Its compact chassis makes it easy to install behind the dash or under a seat, ideal for today’s space‑constrained vehicles. Pair it with the optional ACR‑1 dash remote (sold separately) to control subwoofer level from the driver’s seat.

Key Features

• Six channels of active speaker‑level inputs
  Accepts up to 400 watts per channel at 4Ω – perfect for today’s more powerful factory amplifiers.

• AccuBASS™ bass restoration
  Patented circuit that corrects factory bass roll‑off and restores low‑frequency impact as volume increases.

• Optional ACR‑1 remote level control
  Dash‑mountable knob allows user control of subwoofer output level.

• Internal channel summing
  Combine multiple factory channels to create a full‑range signal when OEM amps use built‑in crossovers.

• GTO™ (Great Turn‑On) Circuit
  Automatically turns the LC7i on when it detects audio signal on the speaker‑level inputs—no need for a traditional remote turn‑on lead from the radio.

• Output level controls
  Fine‑tune preamp output levels for proper gain matching with your aftermarket amplifiers.

• Compact, installer‑friendly chassis
  Easy to mount in tight spaces for clean, professional installations.
