The Leaf Audio Field Amp is a compact, high-performance pre-amp designed for capturing body sound transmission through contact microphones and geophones. With a robust low-noise pre-amplification system, it is tailored to handle Hi-Z signals, offering clear, distortion-free amplification with a powerful output.
The Field Amp features a state-of-the-art low-noise pre-amp that delivers superior performance for a wide range of contact microphones, geophones, and other specialised sound capture devices. It ensures that no unwanted noise or beeping interferes with the signal, even in the high-frequency range, which is crucial when processing or manipulating sound in post-production. The pre-amp provides a clean, pristine audio signal, ideal for both field recording and sound design applications. The device’s gain is adjustable up to approximately 50x, giving the user full control over amplification, while maintaining exceptional signal quality even with longer cable runs.
Weighing just 192 grams (or 410 grams including the case and USB-C to barrel cable), the Field Amp is a lightweight and portable solution for professionals on the move. Its compact size (12 x 12 x 3.4 cm) makes it easy to transport and use in various environments, from studio settings to outdoor field recordings. The included professional case not only protects the unit but also provides ample space for carrying contact microphones, batteries, and cables, making it a convenient choice for sound designers and field recordists who require mobility and organisation.
The Field Amp is specifically optimised to work with Hi-Z signals such as contact microphones and geophones. It acts as an impedance converter, maintaining signal integrity and providing a strong output signal, regardless of cable length. This makes it suitable for various types of microphones, including hydrophones, guitar pickups, and specialised devices such as the Exploding Shed contact mics. For users employing geophones with XLR connectors (such as the LOM models), an additional adaptor cable is required, which is available separately. The device supports both mono input and two mono outputs, one of which is attenuated by -12 dB, allowing flexible routing options.
The Field Amp operates on a 9V DC power supply or a battery, making it adaptable for both stationary and remote fieldwork. A USB-C to barrel connector adapter cable is included for flexible power options. The unit features 3.5mm mono jack connections for both input and output, ensuring compatibility with a wide range of audio equipment. The versatility of the Field Amp makes it a useful tool for sound installations, music production, and any application that requires high-fidelity body sound transmission.
Designed with practicality in mind, the Field Amp includes ¼"-UNC mounts on both the top and bottom of the unit, allowing users to easily mount it to camera tripods or other support systems. This feature provides added stability and convenience, especially when used in dynamic or outdoor recording situations.
The Field Amp enables a significant shift in sound recording, offering a fresh perspective by capturing body sound transmission. Traditional microphones capture airborne sound, which travels through the air before reaching the microphone diaphragm. However, with contact microphones, users listen to sound transmitted directly through materials, opening up an entirely new world of previously hidden sounds. This unique approach to sound design is an essential tool for capturing rich, intricate audio that would otherwise go unnoticed.
The Field Amp offers professionals a robust and versatile solution for high-quality, noise-free amplification, optimised for contact microphones and geophones. Its portable design, combined with excellent power management, makes it a valuable tool for sound designers, field recorders, and audio engineers alike.
