AudioControl LC7i 6-channel line output converter with bass restoration adds aftermarket subs and amps to a factory system (Black)+ Free Absolute Electrical Tape+ Phone Holder Want to add your own speakers, subs, and amps to a factory system? AudioControl's LC7i 6-channel line output converter (LOC) with bass restoration allows you to add aftermarket amps, speakers, and subs to your car's factory radio, so you can enjoy better and more powerful sound without losing climate controls, voice-activated functions, or other built-in factory features. The LC7i accepts speaker-level signals, so you can use it with just about any setup, even high-powered amplified systems. Summing The LC7i sums its input signals together, even if they've been crossed over for tweeters, mids, and subs by the factory system. That way, you can count on a strong, smooth, full-range signal for your processors and amps. The LC7i features six RCA preamp outputs that'll handle a traditional front/rear/sub setup. Why you have to restore the bass Many factory radios actually turn the bass down as you increase the volume to protect the cheap factory speakers, subsequently removing much of your music's power and punch. AudioControl developed a patent pending AccuBASS™ circuit that restores the bass the factory radio erased, giving you much fuller and more enjoyable sound. The AccuBASS is applied to the subwoofer output channel, so your sub amp can have the entire, restored signal to work with. Level-matching with an LED indicator AudioControl makes it easy: set your factory stereo to about 3/4 maximum volume, turn the output level control of the LC7i until the "Maximized" light begins to flicker, then adjust the gain controls on your amps and you're done. You've level-matched the output of your receiver to the amplifier's input, so you can count on getting maximum performance and minimum noise from your system. Convenience The optional dash-mounted ACR-1 wired remote allows you to adjust the volume of the bass while you're on the go. The speaker-level inputs sense incoming signals and turn on the LC7i, while a built-in 12-volt trigger turns on your amps as well. If your factory system only has channels for front and rear speakers, AutoMode™ will create the output you can use for your subs Product highlights: 6-channel line output converter plus bass restoration 6 speaker-level inputs (each can handle up to 400 watts RMS) internal channel summing AccuBASS™ bass restoration circuitry 6 preamp outputs (up to 8.5 volts RMS) level matching controls with Maximized Indicator LED Other Features: optional wired remote subwoofer level controller available (#161ACR1) AutoMode™ turns 4-channel input to 6-channel output GTO™ signal-sensing turn on 12-volt turn-on lead output recommended fuse rating: 2 amps 8-11/16"W x 1-3/8"H x 6-9/16"D warranty: 5 years 6-Channel line output converter (black) Owner's manual QC checklist Absolute BT1700 Vinyl Electrical Tape is good quality, multi-purpose vinyl insulating tape.

AudioControl The Epicenter Digital Bass Restoration Processor (White) You like all the bumpin' bass you hear in hip hop, rap, and EDM? Well you can put that deep, biting bass into any kind of music — from classical, jazz, and rock to folk and Tejano — with an AudioControl Epicenter bass restoration processor. Most factory radios dial down bass response to protect flimsy speakers, so when you do add a subwoofer, there's no bass to play. The Epicenter will bring it back. AudioControl's legendary Epicenter bass processor maximizes the low-frequency power and punch of your bass system, whether it's a simple powered bass tube or a full-blown competition setup. Simply install this processor between your receiver and your amplifiers or crossovers, and you'll finally be able to hear all the good bass you've been missing. An included wired remote lets you control the amount of thump from the front seat. How does it do it? Sophisticated processing analyzes the incoming signal and synthesizes low-bass fundamental tones, increasing bass response tremendously. The Epicenter connects to any receiver with preamp outputs — its balanced inputs will reject noise from your car's electrical system. A subsonic filter removes extreme low frequencies from your signal so your amps and subs will play more efficiently, while a single band ParaBass equalizer lets you fine-tune the bass tone. Upgrade available AudioControl's Epicenter bass restoration processing is also available in The Epicenter Micro, which features a compact chassis, high-level inputs, and selectable load resistors for better OEM factory system integration.
