Part of the DM Essentials product line, it provides a high-performance, cost-effective signal extension solution for conference rooms, classrooms, and display installations where source and display are separated by distances that exceed standard HDMI cable limits.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe kit includes one transmitter and one receiver, designed to work together to extend the full HDMI signal including 4K60 4:4:4 HDR video and eARC (Enhanced Audio Return Channel) audio over industry-standard CATx structured cabling. The eARC capability allows the connected display's audio output to be returned to an AV receiver or DSP at the source end, supporting modern soundbar and home theater audio extraction workflows. RS-232 and IR pass-through enable control of source or display equipment through the same cable infrastructure. Optical audio pass-through provides an additional audio routing path. The DM Essentials line is positioned for installations requiring reliable AV signal extension without the complexity of full DM NVX AV-over-IP infrastructure.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e4K60 4:4:4 HDMI video extension over CATx cable\u003c\/li\u003e\n\u003cli\u003eeARC (Enhanced Audio Return Channel) support for downstream audio extraction\u003c\/li\u003e\n\u003cli\u003eRS-232 pass-through for serial device control\u003c\/li\u003e\n\u003cli\u003eIR pass-through for remote control signal extension\u003c\/li\u003e\n\u003cli\u003eOptical audio pass-through\u003c\/li\u003e\n\u003cli\u003eKit includes matched transmitter and receiver\u003c\/li\u003e\n\u003cli\u003eDesigned for DM Essentials simple deployment without AV-over-IP infrastructure\u003c\/li\u003e\n\u003cli\u003eCompatible with standard Cat 6\/6A structured cabling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConference room display extension from a central AV credenza or rack to a wall-mounted display\u003c\/li\u003e\n\u003cli\u003eClassroom projection and display signal distribution\u003c\/li\u003e\n\u003cli\u003eBoardroom and executive suite AV installations with separated source and display\u003c\/li\u003e\n\u003cli\u003eHotel meeting room and event space AV signal extension\u003c\/li\u003e\n\u003cli\u003eResidential home theater where eARC audio return from display to AV receiver is required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e HD-EARC KIT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVideo:\u003c\/strong\u003e HDMI, 4K60 4:4:4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio Return:\u003c\/strong\u003e eARC (Enhanced Audio Return Channel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Pass-Through:\u003c\/strong\u003e RS-232, IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Audio:\u003c\/strong\u003e Optical audio pass-through\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Type:\u003c\/strong\u003e CATx (Cat 6 \/ Cat 6A recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e Crestron DM Essentials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 1x Transmitter, 1x Receiver\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eQ: What maximum distance does the HD-EARC KIT support over CATx?\u003c\/strong\u003e\u003cbr\u003eA: Maximum extension distance depends on cable quality and gauge. Refer to Crestron's HD-EARC KIT installation documentation for confirmed distance specifications with Cat 6 and Cat 6A cable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is eARC supported on all HDMI sources and displays with this kit?\u003c\/strong\u003e\u003cbr\u003eA: eARC requires both the source\/display and the connected AV equipment to support eARC. The HD-EARC KIT passes the eARC signal through the extension; confirm eARC compatibility at both endpoints before deployment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Does this kit require Crestron control system programming to operate?\u003c\/strong\u003e\u003cbr\u003eA: No. The HD-EARC KIT operates as a standalone signal extender and does not require connection to a Crestron control processor. It can be integrated with a Crestron system for RS-232 and IR control if desired.\u003c\/p\u003e","brand":"Crestron","offers":[{"title":"Default Title","offer_id":47759586394348,"sku":"HD-EARC KIT","price":1320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/master_photo_a-photo-HD-RXC-EARC_Comp.png?v=1781800067","url":"https:\/\/creationnetworks.net\/products\/crestron-hd-earc-kit","provider":"Creation Networks","version":"1.0","type":"link"}
