Kicker KEYLOC Smart Line-Out Converter

This is the Kicker KEYLOC Smart Line-Out Converter.

We regard the Kicker KEYLOC as one of, if not the, best 2 channel line-out converter on the market, due to it's intelligent features such as:

DSP (digital signal processing)
Auto frequency response detection
Auto phase detection 
Signal restoration
Audible EQ Correction

The KEYLOC takes the complexity out of integrating an aftermarket amplifier, into your factory car audio system.

Perfect for adding a powered subwoofer to those vehicles that have factory tuned audio systems.

This revolutionary, DSP (digital signal processor)-controlled, line-output converter automatically detects the frequency response and phase of your factory stereo system, and then allows you to integrate into a more fun, modern entertainment setup!

SIGNAL RESTORATION

In the pursuit to get the best sound possible from your stereo system that features both factory and aftermarket gear, KEYLOC’s patent-pending KEY™ algorithm automatically detects and analyzes crossovers, EQ, time delay, and all-pass filters present, and then it will level-match the left and right audio channels. Once analyzed, it corrects these various filters to give you the smoothest frequency response possible, giving you a clean, uncolored audio signal for your aftermarket gear.

HEAR IT YOURSELF

To hear what you’ve done, cycle the EQ correction on and off with a single push of the KEYLOC’s “KEY” button – hear the before and after! Additionally, if KEYLOC detects any all-pass filters or factory time delay, you can choose to defeat the correction (from the menu) and keep the imaging of the factory source unit. By keeping the correction filter active, KEYLOC will counteract either of these factory effects so you can use an external audio processor to dial in a one-seat tune for the ultimate sound experience.
