Behringer FLOW 4V: 10-track Digital Field Mixer & Audio Interface for Video Production

Cinema-Grade Audio in the Palm of Your Hand

The Behringer FLOW 4V Digital Mixer for Video Production is an ultra-compact 10-track field recorder and USB audio interface engineered for modern filmmaking and streaming. Designed by the team behind the X32 and WING consoles, this hybrid solution eliminates the stress of live gain staging. Whether you are a solo videographer, independent producer, or broadcaster, the FLOW 4V ensures your audio is captured cleanly and in perfect frame-accurate synchronisation on every shoot.

Unclippable Headroom with Legendary Midas Preamps
At the core are four dual-stage Midas microphone preamps delivering 142 dB of dynamic range and -132 dBu equivalent input noise. Rather than relying on a single analogue gain stage, this innovative dual-stage conversion dynamically optimises the input circuitry. Combined with 32-bit float resolution, quiet dialogue remains transparent while sudden peaks are recorded without clipping, allowing you to easily recover dynamics in post-production.

Flawless Camera Sync and Embedded Timecode
Aligning separately recorded audio is a thing of the past. The FLOW 4V features a micro-HDMI port with HDMI-CEC support to automatically trigger recording in perfect sync with your camera. Supporting a built-in SMPTE timecode generator across all common film and broadcast frame rates, it stamps frame-accurate timecode directly into the BWF and iXML metadata so your audio tracks instantly align in post-production.

Location-Proof Power, Pre-Roll, and Automatic Redundancy
Built for run-and-gun operations, the FLOW 4V omits internal batteries in favour of dual hot-swappable USB-C power inputs, running continuously on standard USB power banks. A 5-second pre-roll buffer captures unexpected actions before you even hit record. It also features automatic USB backup; inserting a flash drive into the USB-A port instantly copies completed takes from the internal SD card, securing a duplicate session without a computer.
