BEHRINGER FLOW 4VIO Digital Mixer

Put four more inputs where the guests are sitting.

The camera is at the back of the room, and the four voices are at the table. Clip this I/O box to a mic stand beside them. One StageConnect cable carries their microphones to your FLOW 4V and their headphone feeds back.

Preamps that guard against clipping

Each XLR/¼" TRS combo input feeds a dual-stage preamp with 142 dB dynamic range. The input circuitry prevents clipping without manual gain adjustments. You can still trim levels digitally. Phantom power is +48 V, switchable. On FLOW 4V, these channels get a filter, tone EQ, a choice of dynamics and delay.

Headphones at the table

The two ¼" TRS phones outputs each have their own level control. Output 1 mirrors the FLOW 4V STEREO OUT. Output 2 mirrors its PHONES output. A status LED shows the link: green for OK, red for disconnected.

Power at one end only

Only one device needs external power. Fed 12 V via USB-PD, the host powers the other over an XLR cable, DMX recommended. StageConnect reaches up to 40 m with 110 Ω DMX cable. On its own, FLOW 4VIO also works as a 4 in/4 out USB audio interface.

Features

• StageConnect I/O extender: adds four remote inputs to a FLOW 4V mixer over StageConnect
• Four dual-stage preamps: XLR/¼" TRS combo inputs with 142 dB dynamic range (A-weighted)
• No manual gain setting: input circuitry prevents clipping without manual gain adjustments, and levels can be trimmed digitally
• Switchable phantom power: +48 V on the microphone inputs
• Two headphone outputs: ¼" TRS outputs, each with its own level control; maximum output 72 mW into 30 Ω
• Mirrored monitor feeds: with a FLOW 4V, output 1 mirrors its STEREO OUT and output 2 mirrors its PHONES output
• Processing on FLOW 4V: its four channels get low-cut and high-cut filters, one-knob tone EQ, a choice of dynamics and pre-fader delay
• StageConnect link: 8 upstream and 8 downstream channels with 6 samples latency, up to 40 m with 110 Ω DMX cable
• Power over StageConnect: only one device needs external power; a host fed 12 V via USB-PD powers the other over an XLR cable
• USB audio interface: works on its own as a 4 in/4 out USB audio interface at 48 kHz, 24-bit or 32-bit float, on USB-C
• Combined with FLOW 4V: together they work as a 14 input/4 output USB audio interface
• StageConnect status LED: red for disconnected, green for OK and yellow for occasional transmission errors
• Mic stand clip: comes with a microphone stand clip
