Questions
- What application is the EXT-4KHD70M designed for?
- It is a plug-and-play point-to-point HDMI extender for pushing 4K@60Hz HDR content up to 70M over a single Cat6/6a/7 cable, with bi-directional IR and de-embedded ARC audio for a source-to-display run that needs zero configuration.
- How is the extender wired into an AV system?
- Connect the HDMI source to TX HDMI IN, run a single Cat6/6a/7 cable from TX RJ45 OUT to RX RJ45 IN (up to 70M), and connect the display to RX HDMI OUT. EDID and HDCP negotiate automatically with no configuration required.
- What cable is required and how should it be run?
- Use a single Cat6, Cat6a, or Cat7 cable, STP recommended with proper grounding. Do not bundle the Cat cable with power cables, and do not exceed 70M.
- What audio does the receiver output?
- The RX unit de-embeds ARC S/PDIF digital audio to an optical (Toslink) S/PDIF OUT connector.
- What IR frequency range is supported for pass-through control?
- The extender passes bi-directional IR in the 20-60KHz range using the included IR TX/RX blaster kit.
- How is ARC audio routed to an amplifier?
- The S/PDIF OUT (optical, Toslink) on the RX unit carries de-embedded ARC audio for connection to an amplifier or soundbar.
- How is bi-directional IR control set up?
- Connect the included IR blasters to TX IR OUT and RX IR OUT, and use the IR IN jacks as sensors, to enable remote control between the source and display ends.
- What are the unit dimensions and weight?
- Both TX and RX are housed in a 4.17 x 3.90 x 1.03 in (106 x 99 x 26.2mm) aluminum chassis weighing 0.46 lb (210g) each.
- ARC audio is missing at the amplifier. What should I check?
- Check the optical (Toslink) S/PDIF cable from the RX to the amplifier, check the RX S/PDIF/ARC switch, confirm ARC is enabled in the TV/display settings, and verify the amplifier input is set to optical.
- IR control is not working. What should I check?
- Confirm the IR blasters are pointing at the correct device, verify the IR sensors have clear line of sight, and check that the 3.5mm connectors are fully seated in the IR IN/OUT jacks.
