Two headphone outputs with separate level controls allow users to monitor audio more conveniently during production. This added flexibility is especially useful for field recording, collaborative setups, and content creation workflows that require multiple listening points.

Connect Through StageConnect or USB

StageConnect enables multi-channel audio transmission at sub-millisecond latency using standard XLR cable, supporting 24-bit uncompressed PCM at 44.1 kHz or 48 kHz. The FLOW 4VIO can also operate as a class-compliant 4 x 4 USB audio and MIDI interface for direct computer integration.

Built for Portable Production

Powered via USB-C or compatible XLR StageConnect connections, the FLOW 4VIO is ready for flexible deployment in portable rigs. Its integrated 1/4-20 mount and included mounting screw make it easy to attach to cameras and tripods for streamlined recording and production setups.
