The Crestron HD-EARC KIT pairs the HD-TXC-EARC transmitter with the HD-RXC-EARC receiver to extend HDMI, eARC or optical digital audio, RS-232 and IR over one CAT5e or higher cable. It suits systems where the source is located away from its destination, such as a display, projector or codec.

About the Crestron HD-EARC
Video runs at up to 4K60 with 4:4:4 colour sampling and HDR10, HDR10+ and Dolby Vision, with HDCP 2.3 compliance. The link reaches up to 100 m (330 ft) at resolutions up to 2K and up to 70 m (230 ft) at higher resolutions up to 4K. Power is also extended over the cable, and a PW-2420RU power pack is included with the transmitter.
Audio can travel back from the display end. The HDMI connection to the display supports eARC, covering all Dolby formats up to Dolby Atmos and all DTS formats up to DTS:X, and the transmitter delivers that audio from its HDMI IN/EARC OUT port. Alternatively, an optical signal fed into the receiver's OPTICAL IN comes out of the transmitter's TOSLINK output, carrying Dolby Digital, Dolby Digital EX, DTS, DTS-ES or LPCM up to 6 channels.
Control signals pass through as well: 2-way RS-232 up to 115.2k baud with hardware and software handshaking, 1-way IR up to 60 kHz, plus EDID and CEC. The transmitter's IR output is for an IRP2 emitter, sold separately. Each unit has a low-profile black metal chassis with vented sides and two mounting flanges for surface or rack rail mounting, measuring 105 mm high, 106 mm wide and 27 mm deep.

Questions about the Crestron HD-EARC
What is in the Crestron HD-EARC KIT?
The kit contains the HD-TXC-EARC transmitter and the HD-RXC-EARC receiver. Together they extend HDMI video and audio, eARC or optical digital audio, RS-232 and IR point to point over a CAT5e or higher cable, and the transmitter comes with a PW-2420RU power pack.
How far can the HD-EARC KIT extend a signal?
Up to 100 m (330 ft) for resolutions up to 2K, or up to 70 m (230 ft) for higher resolutions up to 4K, over a CAT5e or higher cable. Video, audio and power are all carried over that one cable between the transmitter and receiver.
How does eARC work with the HD-EARC KIT?
The receiver's HDMI connection to the display supports eARC, covering all Dolby formats up to Dolby Atmos and all DTS formats up to DTS:X. The returned audio travels back over the cable and leaves the transmitter through its HDMI IN/EARC OUT port. Optical audio can be returned instead, via the receiver's optical input and the transmitter's optical output.
What video does the kit support?
It supports up to 4K60 with 4:4:4 colour sampling, plus HDR10, HDR10+, Dolby Vision and Deep Color. At 4K60, 4:4:4 is carried at 8 bit and 4:2:2 at 12 bit. The kit is HDCP 2.3 compliant, and the transmitter input accepts DVI and Dual-Mode DisplayPort sources.
Can a remote display be controlled through the kit?
Yes. The kit passes 2-way RS-232 up to 115.2k baud with hardware and software handshaking, 1-way IR up to 60 kHz, EDID and CEC. The transmitter has an IR input for a Crestron IR control port or other IR source, and an IR output for an IRP2 emitter, sold separately.
How much is the Crestron HD-EARC?
Crestron asks its dealers to give the price of the HD-EARC directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the HD-EARC?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the HD-EARC on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the HD-EARC come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the HD-EARC develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the HD-EARC in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the HD-EARC without installation?
Yes. We supply Crestron to end users, with or without installation. If you are not sure it suits your system, send us the part numbers you already have and we will check.
