The FR-AV4 is more than just a 4-track field recorder – it’s an essential audio solution for videographers, content creators and audio professionals.

With dual A/D converters, Tascam’s Ultra HDDA low-noise microphone preamps, and 32-bit float resolution, the FR-AV4 captures every nuance, from the quietest of whispers to the largest explosions, all with crystal clarity and no fear of clipping. Thanks to a built-in timecode generator and HDMI sync to firmly lock audio to video, this compact and rugged tool is ideal for professional audio recording in virtually any environment.

Dual A/D converters and 32-bit float resolution capture every detail with over 133 dB of dynamic range and zero clipping. Each of the four XLR/TRS combo inputs features low-noise Tascam Ultra HDDA preamps (EIN –127 dBu), delivering pristine clarity, even in the most unpredictable environments.

Record a full multi-microphone setup with confidence. With four inputs and two outputs, the FR-AV4’s built-in mixer offers flexibility while simultaneously capturing all four channels – plus a stereo mix – for 6-track recording directly to SDXC media.

A built-in timecode generator ensures solid synchronisation across your entire setup with no additional gear required. It offers a wide range of timecode sync options, including HDMI I/O, dedicated Timecode In and Out, timecode output for a camera and wireless sync with Atomos via Bluetooth (optional AK-BT2 adapter required).
