KEYLOC DSP Smart Powered Line-Out Converter

The Kicker KEYLOC is a DSP-controlled line-output converter that automatically detects the frequency response and phase of a factory stereo system, then corrects it for a cleaner signal heading into aftermarket gear. Its patent-pending KEY algorithm analyzes crossovers, EQ, time delay, and all-pass filters already present in a factory system, then level-matches the left and right channels and corrects those filters to produce a clean, uncolored signal. A single push of the KEYLOC's button toggles the correction on and off, so an installer can hear the before and after difference directly. Because factory systems do not always send full-range signal down every speaker wire, KEYLOC also reads the available frequency range from any pair of speaker wires through its onboard LEDs, showing low, mid, or high output before any wiring decisions are made. FIT 2+ technology gives it an unusually wide input sensitivity range, from 125mV to 10V on the low-level side and 1V to 40V on the high-level side, letting it work with nearly any factory or aftermarket head unit on the market.
