KEY500.1 Smart Mono Amplifier (bass reveal/processor)
The KEY500.1 is a smart subwoofer amplifier and audio processor in one, featuring an AI-driven DSP (digital signal processing).
Using KICKER's supplied test tones, the KEY automatically analyses the audio being fed into the amplifier. Once this signal has been analysed, the amp will automatically fix peaks in the signal coming in and restore the low bass that is typically missing. In a matter of moments, you get a clean, even bass response from your amp!
