Kicker – 47KEY5001 – Mono Smart Key Amplifier

Auto  EQ

Using KICKER’s supplied test tones (below), the KEY automatically analyzes the audio being fed into the amplifier. Once this signal has been analyzed, 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!
