NV-32-H Network Video Endpoint

The Q-SYS NV-32-H is a network video endpoint native to the Q-SYS Ecosystem, serving as a multi-stream, software-configurable HDMI encoder/decoder that enables network-based video distribution. Optimized for the meeting room, the NV-32-H delivers the right balance of high quality (supporting resolutions up to 4K60 4:4:4), low-latency and network-efficient video distribution across a standard gigabit infrastructure.

Note: This topic provides an overview of the NV-32-H network video endpoint. For installation instructions, see the Hardware User Manual online.

Control

RS-232

Three-pin Euro terminal connection to control third-party devices with Q-SYS Control, user configurable.

GPIO

Three inputs and two outputs for control of third-party devices via Q-SYS Control, user configurable.

Bridging

In addition to its video distribution capabilities, the USB Type-B connection on the NV-32-H acts as an endpoint for the Q-SYS Web Conferencing solution, similar to the Q-SYS Core 110f processor and Q-SYS I/O-USB Bridge. This mode is available when configured as an encoder or decoder. The NV-32-H emulates a webcam video driver (for video streams from the Q-SYS PTZ-IP conference cameras), AEC speakerphone audio driver and multi-channel soundcard driver over a single, driverless USB connection.

Audio

HDMI Audio Input

Each HDMI input is able to receive up to eight channels of PCM audio, which are routable within Q-SYS Designer Software.

HDMI Audio Output

Each HDMI output has the ability to output up to eight channels of PCM audio, making each HDMI output a full-featured Q-SYS audio destination for source audio content, or any other Q-SYS audio feature such as paging, audio playback, etc.

Analog Audio Input

Mic/line input on a 3.5 mm TRS connector, routable within Q-SYS Designer Software, for direct connection of microphones or audio players.

Analog Audio Output

Line output on a 3.5 mm TRS connector, routable within Q-SYS Designer Software, for direct connection of QSC non-networked amplifiers, external speakers or audio recorders.
