Product Overview

The C2G C2G31020 HDBaseT Dual HDMI + USB-C Wall Plate Transmitter to Audio De-Embedding Box Receiver kit extends 4K 60Hz video from either an HDMI or USB-C source over a single Cat6a cable up to 130ft, with integrated audio de-embedding at the receiver end for independent audio system routing. The dual-gang wall plate accepts HDMI, USB-C (video), 3.5mm audio, and USB-B data inputs, while the box receiver outputs HDMI to the display and de-embedded stereo audio to a separate audio system. Designed for conference rooms, classrooms, and training rooms requiring both USB-C and HDMI source support with separate audio management.

Product Description

The dual 4K HDMI and USB-C HDBaseT kit addresses the common commercial AV challenge of accommodating both legacy HDMI sources and modern USB-C laptop video outputs at the same wall plate. The wall plate transmitter handles automatic or manual source switching between HDMI and USB-C, converts both to a unified HDMI signal, and transmits it over Cat6a to the receiver. The 3.5mm audio input allows analog audio from non-HDMI sources to be embedded into the signal path.

The receiver’s audio de-embedder separates the HDMI audio track and routes it to a dedicated stereo output for connection to ceiling speakers, a DSP, or an amplifier independent of the display. USB-B to USB-A data extension supports interactive whiteboards and touch displays. HDCP 2.2 and NDAA 889 compliance cover protected content and government procurement requirements. The kit carries a 5-year C2G warranty.

Frequently Asked Questions

What is audio de-embedding and why is it useful?

Audio de-embedding separates the audio track from the HDMI signal at the receiver and outputs it via a 3.5mm stereo jack. This allows the room’s audio to be routed to a DSP, amplifier, or ceiling speakers independently of the video signal going to the display essential for rooms with separate audio systems.

Does USB-C on the wall plate support video?

Yes. The USB-C input supports DisplayPort Alt Mode video from compatible laptops, enabling 4K video output alongside HDMI sources.

Can both HDMI and USB-C sources be connected simultaneously?

Yes, both can be connected simultaneously. Switching between sources is handled automatically or manually depending on the kit configuration.

Is this NDAA compliant?

Yes. The C2G31020 carries NDAA Section 889 compliance for government and federally funded education projects.
