AudioControl Store

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".

The Epicenter® InDash- InDash Bass Restoration Processor

If you want the best bass possible and a way to measure how loud your system is playing, The Epicenter InDash car audio processor is the perfect product for you. The Epicenter InDash is an expert combination of the bass enhancement circuits along with a microphone and a 160-dB SPL (sound pressure level) display. The display will show real time SPL or hold the highest value so you can show your friends. It will also display voltage so you can monitor your vehicle's electrical systems. With AudioControl's unique Para-Bass equalization control, you select the frequency and bandwidth for the enhanced bass action. The Epicenter InDash car audio processor gives you great bass and a way to see the result.

The Epicenter InDash uses AudioControl's bass restoration circuitry, which actually adds lower octaves of bass to any performance autosound system. In addition, The Epicenter InDash includes AudioControl's Para-Bass equalization, which allows the user to fine-tune the bass response to their specific vehicle. The net result is more bass... louder.

In addition to allowing users to maximize their bass response, the new The Epicenter InDash offers a specially designed microphone mounted on the front panel that can measure up to 160 dB. The SPL is then shown on an LED display on the front panel of The Epicenter InDash. Optionally, users of The Epicenter InDash may select to see their SPL measurement constantly updating or in a peak hold mode. The display also will show the systems power voltage with one tenth volt resolution.

Key Features:

Bring The Bass

AudioControl's The Epicenter InDash bass processor will maximize the low-frequency power of your system, whether you listen to bass from a small tube or a multi-woofer competition setup. Simply install this processor between your car's receiver and your amps, and hear what you've been missing.

Bass Processor Restores the Lowest Frequencies

The Epicenter InDash uses the bass enhancement circuitry of AudioControl's legendary "The Epicenter" bass processor to analyze the signal coming from your headunit, restore low bass tones, and increase your bass response without stressing out your speakers. And you can connect The Epicenter InDash to just about any receiver, thanks to its speaker and preamp-level inputs.

Simple Yet Effective

One twist of the bass knob, and you'll hear the bottom returning to your music. The Epicenter InDash does a great job of pumping up your digital music files or live recordings, restoring low bass that's been lost to compression or poor recording. Separate parametric, Para-BASS controls let you fine tune bass response and allow you to choose the center frequency for the bass maximization circuitry.

SPL Meter for Competitors

You'll also get an SPL display that uses a built-in microphone to measure the sound pressure level of your system. All the way up to 160 dB. A "Peak Hold" setting allows you to show off your system's maximum bump. The display also monitors your battery voltage, a nice feature if you've been playing music with the engine turned off. A warning light lets you know when interior sound levels exceed 120 dB so you can use ear protection. And you can switch the backlight illumination to either red or blue, to go with your car or mood.

EPIC to say the least.

July 23, 2013

This is one awesome little device if you listen to a wide range of music like I do.. I listen to everything from the Moody blues and Doors to Metallica and Decaf - this thing is wonderful for most anything.. ESPECIALLY oldies, rock, and metal. The SPL meter is 5-6 DB off a Termlab in my vehicle, but it is repeatable and works well, all in all my FAVORITE device I have bought in any years. A real game changer if you like to go from Rap to Rock without major setup changes.

Low bass where there's high bass

November 13, 2017

Much better then the 1st generation epicenter's. Built in 160db mic w/display or choose to display voltage. Also you're able to adjust the center & width of frequency. So you can turn a 100hz note into a 27-63hz note. It basically adds low bass to songs without low bass. Note sure if there's a built in subsonic filter.

AudioControl LC7i Black
Best Answer: It would work best connected to the LC7i via RCA cables. If your factory radio has a subwoofer channel output you could connect it to your factory radio using the speaker level inputs then RCA cables to your sub amp. Hope this helps.
