The Essentials For Professional Recording

Super-low-noise microphone preamps

The F4 is equipped with our highest-quality mic preamps. Like the F8, the F4’s mic preamps enable pristine recording and playback at resolutions up to 24-bit/192 kHz. Its impressive audio specs include an extremely low noise floor (-127 dBu EIN) and high gain (up to 75 dB), with +4 dB line-level inputs.

TCXO Time Code

For precise audio/video syncing, the F4 utilizes a Temperature Compensated Crystal Oscillator (TCXO) that generates time code at 0.2 ppm accuracy—a first for this price point. The F4 supports all standard drop frame and non-drop formats, and can jam sync to time code provided by external devices. Standard BNC connectors enable easy integration into any rig.

Advanced onboard limiters

Advanced onboard limiters provide overload protection which lets you capture audio in a wide range of dynamic sound environments. Limiting can be applied to all four channels simultaneously at full resolution, with 10 dB of headroom and controls for setting threshold, attack, and release.

Rock-solid build and lightweight design

A compact metal chassis makes the F4 both rugged and durable, and keeps its weight down to just 2.27 pounds without batteries.

Recording Features

Multi-track recording

With four XLR/TRS combo inputs, a 3.5mm stereo input, and a Zoom mic capsule input, the F4 can record up to six discrete tracks with an additional stereo mix track—all at resolutions up to 24-bit/192 kHz.

Camera return

Input 5/6 can be used as a camera return for monitoring only. This allows you to monitor audio being sent to the camera for confidence checks.

Dual SD card recording

A dual SD card recording feature lets you record simultaneously on two SD/SDHC/SDXC cards* (up to 512 GB each). This means you can instantly back up or split recordings. For example, you can save eight tracks on one card and a stereo mix on another.

File protection

The F4 periodically saves files while recording, providing an extra level of protection from unexpected file interruptions like power loss or sudden SD card removal.

Dual-channel recording

Dual-channel recording mode lets you create safety tracks for inputs 1 and 2, each with independent level, limiting, delay, phase inversion, and high-pass filtering.


Built-in shortcuts allow easy access to important menus and features. Hold the front panel OPTION button for access to TC Jam, Trim Link, Clear Clip and other important shortcuts.

Three power sources

Power up your F4 with 8 AA batteries or an external DC battery pack with a converter cable connector. The F4 also includes a Zoom AD-19 power supply and a DC-HIROSE adapter which serves as a third power option.

The Best Connections


The F4 features four discrete inputs with locking Neutrik XLR/TRS combo connectors. Each input provides a dedicated preamp with gain control knob, phantom power, a six-segment LED level meter, and a Record Ready and PFL switch. The 1/8" stereo input or the Zoom mic capsule input can provide input for tracks 5 and 6. The F4 also includes a variable-frequency slate tone generator to confirm levels.


In addition to the 1/4” headphone jack with dedicated volume control, the F4 provides four other outputs. Two Main Outs (on balanced XLR jacks) let you connect to external mixers and processing devices. Two Sub Outs (on a single unbalanced 1/8" stereo mini-jack) enable easy connection to a camera. The front panel OUTPUT button allows easy access to output levels and routing.

Time code and USB connections

Time code I/O is provided on BNC connectors. The USB port facilitates firmware updates and file transfer. It also allows the F4 to be used as a 6-in/4-out USB audio interface with sample rates up to 96 kHz.

An LCD For All Lighting Conditions

An easy-to-read 1.9-inch white backlit monochromatic LCD display makes the F4 suitable for all lighting environments— from low light to direct sunlight. It also performs well in harsh conditions, like dusty and hard-to-see environments.

Monitor Your Recordings

Flexible options help you easily monitor recordings in the field. Route any input, as well as the stereo track (pre- or post-fader), to the left or right headphone channels. A built-in 100 mW headphone amplifier provides plenty of volume for noisy environments. You can even set headphone alert tones for low battery, recording start/stop, or recording errors.

Onboard Mixer And Effects

An onboard mixer allows for flexible signal routing from all inputs to all outputs (pre- or post-fader) with user-adjustable level, pan, and input/output delay. Built-in limiters can be applied to all channels and tracks simultaneously. The F4 also includes built-in high-pass filtering to reduce the sound of wind and other noise, plus phase inversion and Mid-Side decoding.

The Nitty Gritty

The F4 records in BWF-compatible WAV format at 16-bit or 24-bit resolution, and at any standard sample rate up to 192 kHz. When recording MP3 files, you can choose bit rates of 128, 192, or 320 kbps.
