Which AudioControl line output converter should I choose?
For adding a single subwoofer amplifier to a factory system, the LC2i and LC2i Pro both offer 2-channel conversion with AccuBASS; the Pro version adds selectable input impedance, load selection switches and the ACR-1 remote in the box. The LC1i is the simpler 2-channel option, specified with no AccuBASS processing. Moving up to multi-channel, the LC6i handles six channels of speaker-level input, the LC7i adds AccuBASS and subwoofer control, and the LC7i Pro includes the ACR-1 remote. The LC5i Pro covers five channels with a dedicated bass output, while the LC8i extends coverage to eight channels.
The Epicenter works from a line-level RCA input for bass restoration, delivering up to 13.5 Vrms with the ACR-1 remote included. The Epicenter Micro combines a line output converter with bass restoration, accepting both speaker-level and line-level inputs and including the ACR-4 dual-knob remote. The Matrix Plus is designed to boost an existing head unit preamp output rather than convert speaker-level signals. For remotes, check compatibility carefully — the ACR-1, ACR-2 and ACR-3 each suit different AudioControl products.
