Vizrt Viz Connect Audio 8x4 Analog/NDI I/O Converter with Control & Monitoring

Product Overview

The Vizrt Viz Connect Audio (FG-003297-R001) is a dedicated NDI audio interface providing 8 analog inputs and 4 analog outputs, designed for broadcast studios and live production facilities integrating analog audio sources into NDI workflows. With 48kHz/32-bit conversion, per-channel phantom power, gain control, and an integrated NDI Bridge, the Viz Connect Audio is the purpose-built solution for connecting mixing consoles, microphones, and analog audio equipment to NDI production environments without requiring a general-purpose audio interface or external DSP hardware.

Product Description

The Viz Connect Audio accepts eight analog sources via XLR/1/4" combo inputs, converting them to NDI audio at 48kHz 32-bit resolution for distribution across the production network to TriCaster, 3Play, and any other NDI-capable destination. Four XLR outputs return NDI audio to analog — to speakers, mixers, or amplifiers — completing the audio signal chain in both directions. Per-channel controls for mic/line selection, phantom power on/off, gain, solo, and NDI grouping are accessible directly from the front panel or via the built-in web GUI, without requiring software installation on an external workstation. A headphone output with solo monitoring allows operators to check individual channels in real time. Global SMPTE/EBU clock synchronization ensures audio stays locked to the production timeline. The integrated NDI Bridge enables the unit to route audio locally or across WAN connections to distant locations, making it useful for distributed production and remote commentary workflows. LED status indicators on the front panel provide a visual overview of signal presence, phantom power status, and network state. For AV managers and broadcast engineers adding NDI audio connectivity to productions built around TriCaster or other NDI systems, the Viz Connect Audio eliminates the workarounds typically required to get multi-channel analog audio onto an IP network.

Frequently Asked Questions

Does the Viz Connect Audio require any driver installation?

No driver installation is required. The device is configured and monitored via the built-in web GUI from any browser on the network, and all front-panel controls are accessible directly on the unit.

Can phantom power be controlled per channel?

Yes. Phantom power (48V) is independently switchable on each of the eight input channels, either from the front panel or the web GUI.

How does the NDI Bridge function work?

The integrated NDI Bridge allows the device to route NDI audio streams to and from remote locations over a WAN connection, enabling distributed production scenarios such as remote commentary, off-site mixing, or multi-site live events.

Is the Viz Connect Audio compatible with TriCaster?

Yes. The unit outputs NDI audio that TriCaster systems recognize and accept natively as audio sources, without additional configuration or routing hardware.

How many channels of audio does it send over NDI?

The eight input channels are grouped and transmitted as NDI audio. NDI grouping is configurable per channel from the front panel or web GUI, allowing channels to be combined or distributed independently.
