The TASCAM FR-AV4 brings production-grade audio to modern camera rigs with a slim, aluminum chassis that's easy to mount and tough enough for demanding location work.
A dedicated camera screw mount speeds up setup, while quick-swap BH-4AA battery trays, USB bus power, or an optional AC adapter keep shoots running?from run-and-gun coverage to all-day studio sessions.
A 1.9" color touchscreen and jog wheel provide fast access to routing, metadata, and file management, even when you're on the move.
Locked HDMI and USB ports prevent accidental disconnection, giving you confidence in the field.

Clean Gain, Wide Headroom, and Practical Routing
Four XLR/TRS combo inputs feed TASCAM Ultra HDDA microphone preamps (EIN -127 dBu) and dual A/D converters for ultra-low noise capture.
With 32-bit float recording and over 133 dB of usable range, the FR-AV4 captures every nuance-from whispers to explosions-without fear of clipping.
For tighter file sizes, switch to 24-bit PCM at 48, 96, or 192 kHz. A built-in 4-in/2-out mixer supports isolated channel recording plus a stereo mix to SDXC cards up to 512GB for a total of six tracks (4 channels + stereo mix).

HDMI and Timecode: Locked to Picture
Tight audio-to-video alignment is built in. The FR-AV4 features an onboard timecode generator and HDMI sync using a shared master clock, with support for Blackmagic, Canon, Fujifilm, Nikon, Panasonic, Sony, and more.
Record Trigger lets compatible cameras start and stop the FR-AV4 automatically, minimizing missed takes.
A dedicated 3.5 mm TC I/O and CAMERA TC out expand sync options, while Atomos Bluetooth sync is available with the optional AK-BT2 adapter.
Cascade two FR-AV4 units over HDMI for up to 8 synchronized inputs.
Full 4K/8K video pass-through and embedded multichannel audio allow seamless integration with monitor-recorders.

Advanced Input Processing and Monitoring
Shape audio before it hits the card with onboard EQ, low-cut filter, limiter, and noise gate.
Input/output delay (0-300 ms) helps align feeds in complex rigs.
Flexible monitoring lets you quickly select channels via a dedicated monitor screen, multiple selections can be blended for real-time checks.
Wired and optional Bluetooth wireless monitoring can be used simultaneously with independent volume control-ideal for multi-user sets.

Workflow and Data Security
TASCAM's Auto File Save protects work in progress with updates every 20 seconds.
The built-in tone generator speeds device matching, while TASCAM Audio File Manager software enables quick level adjustments to 32-bit float files without round-tripping into a DAW.
For VR, AR, and 360° productions, Ambisonics mode captures spatial audio in both A-format and B-format (AmbiX or FuMa).

USB-C Interface and App Control
Back at the desk-or live on stream-the FR-AV4 functions as a 6-in/2-out USB-C audio interface for Mac, Windows, iOS, or Android.
Add the optional AK-BT2 adapter for wireless remote control and waveform monitoring via the TASCAM Recorder Connect app.
With REC-LINK, you can trigger simultaneous recording across up to five connected TASCAM devices, including the FR-AV4, FR-AV2, and DR-10L Pro.

Camera-Friendly I/O in a Production-Ready Chassis
Alongside four XLR/TRS inputs, the FR-AV4 includes a 3.5mm CAMERA/EXT input (MONO/ST) with plug-in power (+2.5 V / +5 V), a 3.5mm CAMERA/TC/LINE stereo output, and a 3.5mm headphone jack.
HDMI I/O and cable-lock designs keep everything secure.
Compact, lightweight, and built with a durable aluminum chassis, the FR-AV4 is designed for both mobile and studio environments.
Quick-swap BH-4AA battery trays (additional holders sold separately) and optional AC power ensure uninterrupted shooting on long sessions.
