Do you have a question about the Wyrestorm EX-35-H2-ARC and is the answer not in the manual?
The WyreStorm EX-35-H2-ARC is an 18Gbps 4K HDR HDBaseT Extender with True ARC and Audio Breakout, designed to extend high-bandwidth audio and video signals over long distances. This device is ideal for professional AV installations requiring reliable transmission of 4K HDR content, including 2160p at 4:4:4 60Hz, while also supporting audio return channel (ARC) functionality and audio breakout capabilities.
The EX-35-H2-ARC operates as a transmitter/receiver pair, utilizing HDBaseT technology to send HDMI signals, IR, RS-232, and power over a single Cat6/6a/7 cable. The transmitter (TX) unit connects to the source device (e.g., a 4K HLG or HDR source) via HDMI, and also features an S/PDIF Out and Source Audio Out for audio breakout. The receiver (RX) unit connects to the display (e.g., a 4K HDR HDMI display) via HDMI Out, and includes an S/PDIF In for audio return.
A key feature of this extender is its support for True ARC, allowing audio from the display to be sent back to the transmitter over the HDBaseT link. This is particularly useful for smart TVs or displays with built-in tuners that need to send audio to an AV receiver connected at the source end. The device also supports HDCP 2.2, ensuring compatibility with the latest protected content.
Power over HDBaseT (PoH) is integrated, meaning only one power supply is required for either the TX or RX unit, simplifying installation and reducing cable clutter. The device handles 18Gbps bandwidth, making it suitable for demanding 4K HDR applications with high frame rates and deep color.
The EX-35-H2-ARC is designed for straightforward installation and operation. The front panel of both the TX and RX units features LED indicators for Power, Status, HDCP, and Link, providing quick visual feedback on the device's operational state.
The rear panel offers all necessary connections:
For audio return, the receiver unit includes an "Audio Return Input" switch, which can be set to "ARC" to receive audio from the display via the HDMI connection, or "S/PDIF In" to receive audio from the display via the S/PDIF In connection. This flexibility allows integrators to choose the most appropriate audio return path based on the system design.
The device supports various video resolutions and distances, with performance varying based on cable type (Cat6, Cat6a/7) and resolution. For example, 1080p @60Hz 12bit can be extended up to 70m/230ft over Cat6/6a/7, while 4K HDR signals (e.g., 3840x2160p @24Hz 10bit 4:2:0 HDR) can reach 35m/115ft over Cat6/6a/7.
While the EX-35-H2-ARC is designed for robust performance, proper installation and occasional troubleshooting are key to its longevity and reliability.
The EX-35-H2-ARC is a low-maintenance device once properly installed, designed to provide reliable 4K HDR extension for demanding AV environments. Its robust build and comprehensive feature set make it a suitable choice for professional integration.
