Quality Amplification & Power Management Circuitry

Field Amp is Leaf Audio's solution for the world of body sound transmission: recording the world with contact microphones and geophones.

After releasing their Microphonic Soundbox they quickly noticed that they hit a blind spot. Many sound designers praised the clean and noise-free amplification of it, but had not necessarily use for the Soundbox itself.

They heard you and developed a product on its own - the Field Amp. When you want the Soundbox amp without the actual box, Field Amp will be your new best friend! It's perfect for sound design work or musical applications in the studio, field recording, sound installations and possibly much more.

No noise or beeping can be heard or seen in the spectrum, not even above the hearing range, which would come into focus later during sound manipulation processes. You can record with high sampling rates, transpose the audio by a lot and enjoy your pure sound. Just the clear, pristine audio you want to capture with your contact microphones.

Optimized for Traveling

The small unit is fully portable, light, offers many mounting possibilities. A professional case is included, which also can carry your contact mics, batteries and cables.

Body Sound Transmission vs. Airborne Sound

We are used to listen to the world from our own human hearing perspective. Sound travels through air before it hits the diaphragm of our ear or a microphone. By using contact microphones you switch the hearing perspective from listening to the outside of materials to listening from within materials. This shift is a massive trick for your sound design, which you should try! There is a whole world of sound that normally keeps hidden.

Field Amp is Optimized for Hi-Z Signals like Contact Mics & Geophones

It also acts as an impedance converter with a powerful output signal. No loss of signal quality when you keep the wiring short between microphones and the input. The output is a strong signal and you don't have to worry about a few meters of cable. We recommend using the shielded contact microphones by Exploding Shed.
