Professional Sound Reliability
Dual A/D converters and 32-bit float analysis provide over 133 dB dynamic range with extremely low distortion. The four XLR/TRS combo inputs feature Ultra HDDA low-noise preamps (EIN –127 dBu), ensuring top-notch clarity even in the most demanding environments.
Advanced Recording & Mixing Technology
The built-in mixer allows flexible routing: record four channels plus a stereo mix (total 6 channels) directly to an SDXC card.
Precise Synchronization
The integrated timecode generator ensures stable synchronization across the setup without additional equipment. It supports HDMI I/O, dedicated timecode input/output, camera output, and wireless synchronization with Atomos via Bluetooth (optional AK-BT2 adapter).
32-bit Float Audio Interface
The FR-AV4 also functions as a USB-C audio interface with 6 inputs and 2 outputs for Mac, Windows, iOS, and Android – with the same wide dynamic range and clipping-free recordings.
Camera Synchronization via HDMI
With a simple HDMI connection, the FR-AV4 accurately synchronizes audio and video, supporting auto start/stop recording depending on the camera's operation.
