HDMI eARC/ARC & Optical SPDIF Audio Extender over Cat5e/6 [328ft]

Bring long-distance digital audio where you need it with the J-Tech Digital JTECH-AET-EAS HDMI eARC/ARC and Optical SPDIF audio extender. Designed for home theaters, AV racks, conference rooms, and commercial audio installations, this transmitter and receiver kit extends HDMI eARC/ARC audio up to 328 ft or Toslink Optical SPDIF audio up to 656 ft over a single CAT5e/6 cable. A built-in selector switch on the transmitter makes it easy to choose between eARC/ARC and Optical SPDIF extension modes for flexible integration with different audio systems. HDMI eARC supports PCM 2.0/5.1/7.1, Dolby Digital Plus, Dolby TrueHD, DTS-HD MA, and Dolby Atmos, while HDMI ARC and Optical SPDIF support PCM 2.0, Dolby Digital up to 5.1, and DTS 5.1. Bi-directional Power over Cable feature allows the system to operate with just one included 12V power adapter connected at either the transmitter or receiver side, helping simplify installation. When using HDMI eARC/ARC mode, CEC pass-through also helps maintain compatible device control between connected TVs, AV receivers, and audio equipment.
