The HD-EARC KIT consists of a transmitter (HD-TXC-EARC) and receiver (HD-RXC-EARC), which enable the extension of HDMI® AV and eARC (Enhanced Audio Return Channel) or optical digital audio signals. This is useful in applications where an AV source is located remotely from its destination, such as a display, projector, or codec solution. A CAT5e or greater twisted pair cable must be used to connect the transmitter and receiver.
4K60 4:4:4 and HDR Support
The HD-EARC KIT supports video resolutions up to 4K60 with 4:4:4 color sampling. HDR10, HDR10+, and Dolby Vision® video formats are also supported1.
eARC and S/PDIF Audio Extraction
The HDMI output of the HD-RXC-EARC receiver supports Enhanced Audio Return Channel (eARC) connectivity, allowing audio to be extracted from a connected display and transmitted back to the HDMI connector of the HD-TXC-EARC transmitter. Extracting audio from the display via the eARC connection means only a single cable is required for video and bidirectional audio. An optical TOSLINK® S/PDIF input is also available on the receiver to extract 2-channel LPCM digital audio from the display. These connections allow local audio content from the display (such as smart TV streaming applications) to be sent back to the transmitter. The HDMI/OPTICAL switch on the transmitter determines which audio output connection on the HD-TXC-EARC is prioritized.
Compact, Surface-Mountable Design
Compact in design, the transmitter and receiver of the HD-EARC KIT can be mounted onto a flat surface such as a wall behind a flat-panel display or on a ceiling above a projector. They can each also be attached to a single rack rail in the back of an equipment cabinet. The power pack supplied with the HD-TXC-EARC transmitter powers both units in the kit.
