Lightware expands Gemini GVN with full-feature USB-C

Lightware Visual Engineering announces the GVN-HC-TX220AP, a new transmitter in the Gemini GVN 1G AV-over-IP family that introduces full-featured USB-C for professional 1Gb AV-over-IP deployments. Built for USB-C-first collaboration spaces, it is designed to help organisations deliver a cleaner, more intuitive experience without needing to upgrade network infrastructure.

At the heart of the GVN-HC-TX220AP is a primary USB-C input that can carry video, USB 2.0 data, 2x2 channel audio, and Ethernet over a single connection, while also supporting up to 100 W Power Delivery when the unit is powered by an external PSU. For rooms that still need a second input, a secondary host path combines HDMI 2.0 with a USB-C link for USB 2.0 data, 2x2 channel audio, and Ethernet.

The device is designed to keep meetings moving. Configurable auto-select can switch between the USB-C and HDMI host inputs based on signal presence or priority to reduce friction at the table. On the USB-C input, users can inject up to 4K60 4:4:4 video with audio, aligning with modern laptop outputs and presentation requirements.

The GVN-HC-TX220AP delivers 4K60 at 3 ms latency. For network connectivity, it offers dual RJ45 ports and an SFP cage, supporting copper (CAT) and fibre-based installations. Alongside USB over IP - ideal for HID devices, webcams, microphones and speakerphones - the unit also features a native bidirectional USB audio (UAC) interface on both host inputs (with one active at a time). For local monitoring, the transmitter includes an uncompressed HDMI 2.0 loop-out for mirrored preview and a stereo analogue audio port with selectable input or output operation.

For projects that require professional audio over IP, Lightware also offers the GVN-HC-TX220AP-DNT variant. It adds 2-channel bidirectional Dante capability, enabling flexible audio routing between HDMI, analogue, USB and Dante networks. The transmitter integrates with the GVN Matrix Management Unit (MMU) for auto-discovery, centralised configuration, EDID management and monitoring. It can be powered via PoE/PoE+ for simplified installations.
