Black Box 328ft HDMI 2.0 Extender over CATx

The Black Box AVX-HDMI2-HDB-R2 is an HDMI 2.0 extender that sends uncompressed ultra-high-definition video, multichannel audio, power, and IR control through a single CATx cable. It bridges a gap of up to 328 feet between a source and a display without introducing compression or latency, so the picture you see on the far end looks exactly like the one coming out of the player or switcher.

With support for 4K resolution at 60 Hz in full 4:4:4 color and HDR, the extender keeps every frame sharp and every color true. HDCP 2.2 compliance allows it to handle protected content from Blu-ray players, streaming devices, or set-top boxes without issue, making it a reliable choice for modern home theaters and professional AV installations alike.

Control is covered as well. Bi-directional IR pass-through lets you operate the source from the display side or vice versa, while an RS-232 link offers integrators a straightforward path to system automation. One-way Power over Cable means you only need to power one unit, which simplifies wiring and opens up placement options where outlets are scarce.

The housing follows a low-profile design, so the units tuck neatly behind flat-panel displays, inside lecterns, or within equipment racks. A locking HDMI connector prevents accidental disconnections that can interrupt a presentation or viewing session, a detail installers will appreciate when working in classrooms, conference rooms, sports bars, or digital signage networks.

If you need to place a projector at the back of a long auditorium, feed menu boards across a busy kitchen, or link a media player to a living-room TV on the other side of the house, this extender gives you the reach and reliability to do it with confidence.
