WolfPack 8K 4K120 HDMI Extender over HDBaseT 131 feet Cat6a/7

What Is the WolfPack™ HDTV-EXT8K-40M-HDBT?

The WolfPack™ HDTV-EXT8K-40M-HDBT is a professional-grade HDMI 2.1 extender kit from HDTV Supply that transmits 8K@30Hz 4:4:4, 8K@60Hz 4:2:0, and 4K@120Hz video signals over a single Cat6a or Cat7 cable — up to 40 meters (131 feet). Built on the HDBaseT 1.0 standard, it supports the full HDMI 2.1 bandwidth of 40 Gbps.

Unlike conventional 4K HDMI 2.0 extenders limited to 18 Gbps, this unit handles next-generation display resolutions and frame rates — including 1080P@240Hz for high-refresh gaming, Dolby Atmos and DTS:X immersive audio, and HDR10 high dynamic range video — all over a single structured cable with no signal degradation.

The slim, rack-mountable transmitter and receiver units include bidirectional Power over Cable (PoC), meaning a single power adapter at either end powers both units. Bidirectional IR and RS-232 passthrough allow full remote control of source and display devices from either end of the installation.

Installation Guide

1. Plan Your Cable Run

   Measure the distance between your source device and display. For runs up to 35m, Cat5e or Cat6 is acceptable. For runs up to 40m, use Cat6a or Cat7. Route the cable through walls, ceilings, or conduit as needed. Avoid running parallel to AC power lines to minimize interference.

2. Connect the Transmitter (TX)

   Connect your HDMI source (Blu-ray player, gaming console, PC, cable box) to the HDMI IN port on the transmitter using a standard HDMI 2.1 cable. Connect the Cat6a cable from the transmitter’s RJ45 port and route it to the display location.

3. Connect the Receiver (RX)

   At the display end, connect the Cat6a cable to the receiver’s RJ45 port. Connect the receiver’s HDMI OUT port to your display using a short HDMI cable. If using de-embedded audio, connect a 3.5mm cable from the receiver’s AUDIO OUT jack to your amplifier or speaker system.

4. Power the System

   Connect the included 5V/3A power adapter to either the transmitter or the receiver — not both. The bidirectional PoC feature will automatically power the other unit through the Cat6a cable. The POWER LED on both units will illuminate green when powered correctly.

5. Configure EDID (if needed)

   In most installations, the default Copy EDID mode works correctly. If your source device does not output the correct resolution, use the DIP switches on the transmitter to select a fixed EDID mode:

   DIP SW 1	DIP SW 2	EDID Mode
   OFF	OFF	Copy EDID from display (default)
   ON	OFF	Fixed 4K@60Hz EDID
   OFF	ON	Fixed 4K@30Hz EDID
   ON	ON	Fixed 1080P EDID

6. Connect IR & RS-232 (optional)

   For bidirectional IR control, connect the IR blaster cable to the IR OUT port on the transmitter and aim it at the source device’s IR sensor. Connect the IR receiver cable to the IR IN port on the receiver. For RS-232 control, connect serial cables to the 3-pin terminal blocks on both units.
