Zoom F3: The 32-Bit Float Field Recorder That Eliminates the Gain Knob

Every traditional field recorder forces the operator to make a guess before the take rolls. Set the gain too low and quiet dialogue lives in the noise floor; set it too high and a sudden peak — a slammed door, a shouted line — clips and the take is gone. The Zoom F3 ends that gamble. Its dual A/D converter circuit captures every level in 32-bit float at the same time, with virtually unlimited headroom and recoverable peaks. Boom operators on narrative sets, documentary crews capturing dialogue on the move, foley artists working loud props, and run-and-gun YouTubers all get the same thing: a recorder that records cleanly without intervention, every time.

How Dual A/D Conversion Delivers Real 32-Bit Float Capture

Inside the F3, two analog-to-digital converters run in parallel on every input channel. One handles low-level signal cleanly down to the noise floor; the other handles high-level signal cleanly through +24 dBu maximum input. Firmware combines both streams into a 32-bit float WAV file with the dynamic range of both converters stitched together. The result is a recording where a whispered aside and a slammed prop in the same take are both fully usable in post — no choosing between clean dialogue and unclipped impacts. The -127 dBu equivalent input noise on the preamps means even the F3's own electronics are quieter than the microphones it's recording.

Two Locking XLR/TRS Combo Inputs with +48V Phantom Power

Both inputs are locking XLR/TRS combo jacks — XLR for traditional shotgun and broadcast mics, 1/4-inch TRS for wireless receivers and line-level sources. Phantom power switches per channel, so a condenser shotgun on channel one and an unpowered dynamic on channel two share the same recorder without compromise. The locking XLR is non-negotiable for boom work where a yanked cable mid-take ruins the scene. The combo TRS jack matters because Wireless GO and similar wireless receivers output to 3.5mm TRS — the F3 takes that directly without a TRS-to-XLR adapter cluttering the rig.

Why the F3 Belongs on a Boompole, a Tripod, or in a Costume Pocket

At 3 inches by 3 inches and 8.5 ounces with batteries installed, the F3 is the smallest field recorder Zoom has ever shipped. The metal housing, side bars, and slide-resistant rubber feet are rated for production handling, and the 1/4-20 thread on the bottom mounts the recorder directly to any tripod plate, light stand accessory clamp, or boompole adapter. Hidden drop rigs and lavalier recording setups benefit from a recorder small enough to disappear under a costume. The compact body and 8+ hour 2x AA runtime mean one recorder covers a full day of shooting without battery management overhead.

USB-C Class-Compliant Audio Interface for Computer and iOS

The F3 doubles as a 2x2 USB-C audio interface up to 96 kHz / 32-bit float — class-compliant on Mac, Windows, and iOS without drivers. Podcasters, streamers, and home studio musicians who already own XLR mics can plug straight into the F3 and run it through any DAW, conferencing app, or streaming software with the same 32-bit float headroom that the field recording mode delivers. The loopback function combines computer audio with the F3 inputs for streaming setups, and USB bus power runs the unit indefinitely with no battery drain.

Built for Filmmakers, Documentary Crews, and Sound Designers Who Refuse to Lose a Take

The F3 is for the operator who has lost takes to bad gain settings and is done with it. It is for the documentary crew that cannot stop the action to dial in levels. It is for the foley artist whose props are unpredictable and whose recorder cannot be. And it is for the indie filmmaker who needs broadcast-quality 2-channel capture in a body small enough to disappear into the set. Two preamps, two locking inputs, 32-bit float, 8 hours of battery — and zero gain decisions to make before the take rolls.
