Behringer FLOW 4VIO StageConnect I/O Extender
Behringer FLOW 4VIO extends the input and monitoring capacity of FLOW 4V with four dual-stage microphone preamps and two additional headphone outputs. StageConnect carries uncompressed digital audio and power over one cable. Meanwhile, 32-bit float recording and USB audio/MIDI suit professional video production workflows.
More Inputs for Production Workflows
Firstly, four dual-stage microphone preamps extend the available input capacity for professional video production workflows. Alongside 32-bit float recording, they give the system a practical way to manage microphone sources while keeping the expander’s role clear. That is, to add I/O to a FLOW 4V setup through StageConnect.
Independent Headphone Monitoring
Moreover, two headphone outputs add monitoring flexibility, bringing the system to three independent outputs in total. The headphone amps can drive very high-impedance over-ear headphones and avoid distortion with lower-impedance in-ears. Therefore, multiple people can monitor clearly without splitters or workarounds.
One Cable, Long Reach
Furthermore, StageConnect carries the signals and power between the expander and FLOW 4V through one cable, with a distance of up to 40 meters. Use a standard XLR mic cable up to 5 meters or a DMX cable up to 40 meters, with sub-millisecond latency and uncompressed digital audio.
Flexible StageConnect Expansion
USB audio/MIDI adds another listed capability, while compatibility with other StageConnect devices lets FLOW 4VIO be combined within a wider StageConnect setup. Its digital stagebox format keeps the unit focused on expanding inputs and monitoring where the workflow needs them.
