The Behringer FLOW 4VIO is the suitable I/O extension for FLOW 4V mixers and provides noticeably more connection and production options in a compact way: With four additional microphone preamps and two-stage A/D converters, the device gets maximum dynamics and detail resolution out of every source - ideal for demanding voice, vocal and instrument recordings. Two headphone outputs, each with its own volume control, are available for direct monitoring so that two users can monitor independently of each other.

In addition to its function as an extension, the FLOW 4VIO also works as a class-compliant USB audio/MIDI interface and can therefore be used in common setups without driver installation. Furthermore, StageCONNECT offers multi-channel audio transmission with less than 1 ms latency, 24-bit uncompressed PCM at 44.1/48 kHz - via a standard XLR cable. Especially practical: This StageCONNECT connection can even be used to remotely power a connected FLOW 4V field recorder and mixer if required, also via a single XLR cable. Alternatively, the FLOW 4VIO can also be used as a class-compliant 4×4 USB audio interface or - in conjunction with a Behringer WING StageConnect port - as a 4×4 channel I/O extension including remote power.

The power supply is versatile via USB-C (power supply included) or - with compatible devices - via XLR via StageCONNECT. For maximum practicality, there is also an integrated 1/4"-20 thread with mounting screw, which allows the FLOW 4VIO to be mounted directly on cameras or tripods; an integrated Allen key rounds off the setup for mobile use.
