Overview

The AV Access 4KEX70-ARC-H2 HDMI Extender is a flexible HDBaseT solution designed for modern home theaters and multi‑room setups. It enables TV audio to travel farther than typical HDMI runs, supports ARC audio return, and includes a built‑in audio extractor to route sound to amplifiers, soundbars, or receivers. This design helps you keep a clean signal path without sacrificing audio quality or control.

With careful engineering and practical features, this extender targets real‑world setups where space, wiring, and device placement matter. It emphasizes reliable transmission, straightforward installation, and adaptable input options, so you can tailor the system to your room layout without guesswork.

Key benefits at a glance

• True 4K video with HDR and 4:4:4 color support for movies, gaming, and presentations.
• Long reach over a single Cat6a/7 cable: up to 131 feet for 4K and 230 feet for 1080p, reducing cable clutter.
• One cable carries video, audio (ARC or external), IR/RS232, and power, simplifying installation.
• Built‑in audio extractor outputs digital coax S/PDIF and analog via Phoenix connectors for versatile connections to AVRs or multi‑room zones.

Flexibility, control, and reliability

• DIP switch selects TV ARC audio return or external S/PDIF input, giving you adaptable configurations for different systems.
• Bi‑directional IR and RS232 signals enable remote control from either end of the link.
• HDBaseT with lossless transmission keeps the signal stable over long runs, reducing flicker and drop risks.
• LED status indicators help technicians verify power and signal presence during setup and troubleshooting.

Real‑world use cases

Imagine a wall‑mounted TV in a living room with the AV receiver in a separate cabinet. A single Cat6a/7 cable can carry video, sound, and remote signals to the display, while the ARC return sends TV audio back to the speakers. In a multi‑room layout, you can feed a dedicated speaker zone or soundbar without running extra cables.

In a small conference room or home office, the extender can bridge HDMI from a compact source to a projector or display in another area, keeping control paths tidy and organized.

Notes for best results

Performance depends on cable quality and environment. For 4K playback, use a capable Cat6a/7 cable and ensure compatibility with ARC‑enabled TVs and receivers. Results may vary with older equipment, and real‑world behavior can depend on your specific setup.
