Frequently Asked Questions - HD-EARC KIT Crestron

What is the maximum distance the HD-EARC KIT can transmit?

The HD-EARC KIT supports transmission up to 100 meters (328 feet) over a single CAT6a or CAT7 cable.

Does it support eARC audio?

Yes, the kit fully supports eARC (Enhanced Audio Return Channel) for high-bandwidth audio formats like Dolby Atmos and DTS:X.

Can I use it with a standard HDMI cable?

No, the kit requires a CAT6a/7 Ethernet cable for extension; HDMI cables are only used for local connections between source/display and the transmitter/receiver.

Do I need to configure anything before use?

Basic setup is plug-and-play, but you may need to adjust EDID settings via DIP switches on the units for compatibility with certain displays or sources.

What power supply is required?

Each unit is powered via 5V DC USB-C (cable and adapter included). Do not use third-party adapters.

Is the HD-EARC KIT compatible with 8K?

Yes, it supports 8K@30Hz and 4K@60Hz with full chroma 4:4:4, thanks to HDMI 2.1 compliance.

Can I daisy-chain multiple units?

No, this is a point-to-point extender. For multi-room distribution, you would need a matrix switcher with HDBaseT technology.

How do I clean the units?

Use a soft dry cloth to wipe the exterior. Do not use any liquids or solvents.

What should I do if there is no video output?

Check all connections, ensure both units are powered, verify the CAT cable is not damaged, and try a different EDID setting on the transmitter.

Where can I find the full manual?

The full manual is available for download on the Crestron website or through the QR code included in the box.

Overview

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 digit signals. This is useful in applications where an AV source is located remotely from its destination, a display, projector, or codec solution. A CAT5e or greater twisted pair cable must be used to the transmitter and receiver.

NOTE: Power is transmitted over the CATx cable that connects the transmitter to the receiv

4K60 4:4:4 and HDR Support

The HD-EARC KIT supports video resolutions up to 4K60 with 4:4:4 color sampling. HDR10, HDR Dolby Vision® video formats are also supported

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 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 opt

TOSLINK® S/PDIF input is also available on the receiver to extract 2-channel LPCM digital audio display. These connections allow local audio content from the display (such as smart TV s 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 surface such as a wall behind a flat-panel display or on a ceiling above a projector. They are attached to a single rack rail in the back of an equipment cabinet. The power pack supplied by HD-TXC-EARC transmitter powers both units in the kit.

Note:

1. For the DM CATx cable connection, use Crestron DM-CBL-8G, Crestron DM-CBL-ULTRA, or third-party CAT5e or greater cable. To safeguard against unpredictable environmental electrical noise that may impact performance at resolution above 1080p, shielded cable and connectors are recommended for all applications, and are required when bundlin multiple cables in a wire run. Wire and cables are sold separately. The DM Essentials ports in this kit are not compatible with DigitalMedia 8G+®, HDBaseT®, PoE, or PoDM technology or any other type of CATx based interface or net

Installation Guidelines

Before installing the device, be aware of the following information regarding DM Essentials cabling, HDMI cabling, and the power connection to the device.

DM Essentials Cabling

The DM Essentials output port (DM OUT) of the HD-TXC-EARC transmitter must be connected to DM Essentials input port (DM IN) of the HD-RXC-EARC. For DM Essentials connections, use Crestron DM-CBL-8G, Crestron DM-CBL-ULTRA, or third-party CAT5e or higher cable (Crestron DM-CBL Series cables are sold separately).

NOTE: Cables that can be used for DM Essentials connections are designed for intrabuilding use only.

To safeguard against unpredictable environmental electrical noise that may impact performance of resolutions above 1080p, shielded cable and connectors are recommended for all applications and required when bundling multiple cables in a wire run.

NOTE: The HD-EARC KIT does not support interlaced video.

HDMI Cabling

4K60 4:4:4 performance and HDR support require the use of HDMI cables and couplers with TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30 4:4:4 performance is acceptable, cables are with a minimum bandwidth of 10.2 Gbps can be used. Bandwidth loss is cumulative; therefore, performance may be reduced when inserting multiple cables and couplers inline.

An HDMI input requires an appropriate adapter or interface cable to accommodate a Dual-Moc DisplayPort™ or DVI signal. An HDMI output requires an appropriate adapter or interface cable accommodate a DVI signal. Crestron CBL-HD-DVI interface cables are sold separately.

Power Connection

A 24VDC power pack is included with the HD-TXC-EARC transmitter. This power pack supplies both devices in the HD-EARC KIT via the DM Essentials connection.

Connect the Device

Make all necessary connections to the HD-EARC KIT as shown in the following diagrams:

HD-TXC-EARC Front Panel Connections

HD-TXC-EARC Rear Panel Connections

HD-RXC-EARC Front Panel Connections

Set the HDMI/OPTICAL Switch

The HD-TXC-EARC transmitter features a two-position HDMI/OPTICAL slide switch on its rear panel.

This switch determines which audio output of the transmitter to prioritize. If this switch is not properly, certain combinations of audio input at the HD-RXC-EARC and audio output at the HD-TXC-EARC will prevent audio from passing.

Set the HDMI/OPTICAL switch to HDMI to prioritize the HDMI IN/eARC OUT port of the HD-TXC-EARC as the audio output. With this position selected:

- An eARC audio signal connected to the HD-RXC-EARC will be available only from the HI IN/eARC OUT port of the HD-TXC-EARC. This signal will not be available from the OPTI port of the HD-TXC-EARC.

- An ARC audio signal connected to the HD-RXC-EARC will be available from both the HD IN/eARC OUT and OPTICAL OUT ports of the HD-TXC-EARC.

- An S/PDIF audio signal connected to the HD-RXC-EARC will not be available from either HDMI IN/eARC OUT or OPTICAL OUT ports of the HD-TXC-EARC. No audio will pass from either connector in this configuration.
