High-level input line output converter More and more aftermarket amplifier installations depend on using the factory amp's powered outputs for its inputs. AudioControl's LC2i PRO line output converter takes amplified speaker-level signals and converts them into high-quality preamp signals that can then be fed to another processor, a full-range amplifier, or your subwoofer amp. Bass feature Some factory radios dial down the bass as you turn up the volume to protect the flimsy factory speakers. The problem is, they don't give it back when you upgrade to a nice set of aftermarket speakers. AudioControl packs the LC2i PRO with their AccuBASS(tm) circuitry that reverses the factory low-frequency roll-off, giving you the bass you need to enjoy your music to the fullest. Installation conveniences The included dash-mount wired remote control allows you to adjust the level of your sub channel on the go. Load selection switches make OEM integration easier, so the LC2i PRO will work with almost any factory sound system. Selectable turn-on modes include GTO(tm) Signal Sense (DC offset), audio sense, or remote 12 volt inputs.
