It adds four dual-stage microphone preamps and two headphone amps, extending input and monitoring capacity for professional video production workflows. FLOW 4VIO adds four no-clip mic preamps, doubling your system to a total of eight. Built to the exact same dual-stage, true 32-bit architecture as FLOW 4V, they deliver up to 142 dB of dynamic range. Impressive! Expanded Headphone Monitoring Need everyone to hear clearly on set? FLOW 4VIO adds two headphone amps, giving you three independent headphone outputs in total. They can drive very high-impedance over-ear headphones and also avoid distortion on lower impedance in-ears. No splitters, no workarounds.
