The AUDIOROOT FEMTO is a high quality battery powered mic preamp that was designed for location sound recording (
ENG, EFP, music, etc…). It combines in a single box a high gain – low noise microphone preamp with 48V phantom
powering, a 80hz 12dB/oct high pass filter and a beautiful OLED screen for audio and battery level information
display. The FEMTO was designed to resist over time and against the harshest environments. The FEMTO’s premium
electronics are protected by a lightweight powder coated aluminum extruded enclosure. Markings are directly engraved
on the aluminum face panels to resist over time. The AUDIOROOT FEMTO is a high gain mic preamp with a default
minimum gain setting of +10dB.
