KeyPre®

 







KP6 Audio Line Amplifier

The KeyPre® was designed for professional keyboard, synthesizer, and drum machine users who want to use something better than a mixer input channel or a DI (direct injection).

Electronic instruments often have a wide range of different output levels and impedances, and with much wider bandwidth than traditional passive instruments such as electric guitars.

This presents a challenge for any outboard device following it. A high performance preamplifier, specifically designed for electronic instruments, is needed to ensure nothing is being compromised or bottlenecked as your sound is being processed.

Over two years have been dedicated to research, test, and develop the KeyPre® and we are confident it will preserve the integrity of your electronic instrument for both recording and live applications.
