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.
