Mutable Instruments Ears

The Mutable Instruments Ears Contact Microphone features a built-in amplifier with 1m input impedance, a 40dB gain and width of 4HP. Ears is a contact microphone and amplifier that allows you to generate a large variety of sounds by scratching, tapping, and more generally collecting any kind of acoustic waves surrounding your modular case, including speaker feedback.

A built-in amplifier section can provide up to 40dB of gain, with a high impedance input suitable for guitars or other electro-acoustic instruments. It will deliver clean amplification for line level signals or external contact microphones. Ears has been augmented with an envelope follower, and its amplification section has been redesigned from scratch for low noise and low distortion.
