1x Kicker 53KEY2004 KEY 4-Channel DSP Smart Amplifier, 4x50W (53KEY2004)
KEY200.4 – 200-Watt 4-Channel Amplifier with AI-Driven DSP
The KEY200.4 combines a compact 4-channel amplifier with automatic audio processing designed to improve clarity, tonality, and soundstage. Its internal processing uses an included microphone to automatically configure a 40-band equalizer, time alignment, speaker-size detection, and 24dB crossovers, while delivering 50 watts per channel at 4 ohms.
Overview
Amplification and Automatic DSP in One Compact Chassis
The KEY200.4 provides 200 watts of total power in a chassis measuring just 1-11/16 inches high, 2-3/4 inches wide, and 7-3/8 inches long. Its small footprint allows installation behind a radio, under a seat, or in a trunk.
In addition to amplification, the KEY200.4 uses an internal computer and included microphone to automatically analyze and correct the audio system. Processing includes automatic equalization, time alignment, speaker-size detection, and crossover configuration.
Power & Performance
50 Watts x 4 at 4 Ohms
- 200 watts total power (50 watts x 4 channels).
- 20Hz–20kHz frequency response, +0/-1dB.
- Signal-to-noise ratio greater than 90dB, A-weighted, referenced to rated power.
- High-level input sensitivity from 250mV to 10V.
- Bi-amp capability with defeatable operation.
Automatic Audio Processing
Microphone-Based System Correction
Press the selector and the included microphone allows the KEY200.4 to analyze the system and apply automatic processing. A 40-band equalizer adjusts tonality, while automatic time alignment and speaker-size detection help configure the system for improved soundstage and speaker performance.
Vehicle Integration
Designed for Factory and Aftermarket Systems
FIT2™ (Fail-Safe Integration Technology) provides compatibility with nearly every stock and aftermarket radio. The amplifier can turn on through either a remote 12-volt signal or DC offset and is compatible with newer vehicles using start-stop technology.
- FIT2™ integration technology included.
- Compatible with start/stop vehicle technology.
- Remote 12V or DC-offset turn-on.
- High-level input sensitivity from 250mV to 10V.
Dynamic Power Management
Automatic Peak Management
When the amplifier reaches its temperature threshold, dynamic power-management algorithms engage a limiter/compressor on musical peaks. The processing is applied for as little as milliseconds at a time while the amplifier cools, then disengages so the music returns to its full dynamic range.
- Automatic compressor functionality.
- Compressor can be defeated.
- Processing is applied to musical peaks when the temperature threshold is reached.
