Many AV projects begin with a simple requirement:
Transmit HDMI signals over long distances.
However, today's systems demand much more than video transport.
Modern displays now include:
As displays become content sources, audio must often travel back to amplifiers, soundbars, or DSP processors.
This is where ARC becomes essential.
A company installs a 98-inch display in a conference room.
The AV rack is located 30 meters away in a separate equipment closet.
Employees frequently use:
Audio generated by the display must return to the room's ceiling speaker system.
Without ARC:
Additional audio cabling is required.
Using the GPro EX70H2:
Result:
A cleaner and more reliable installation.
A homeowner mounts a large 4K TV on the wall.
The AV receiver is hidden in a cabinet or equipment room.
Streaming services are accessed directly from the TV.
Without ARC:
Extra optical cables are required.
The EX70H2 provides:
Result:
A clean home theater with fewer visible cables.
Guests use smart TV applications to access streaming content.
Audio must be routed through soundbars or integrated speaker systems.
Traditional solutions require separate audio return wiring.
ARC-enabled HDMI extension simplifies installation while improving reliability.
Result:
Reduced installation costs across multiple rooms.
Large teaching displays are often located far from equipment racks.
Audio generated by educational software or streaming content must be distributed through classroom speakers.
The EX70H2 combines:
Result:
Simplified classroom AV infrastructure.
Built-in HDMI downscaling allows 4K and 1080P displays to coexist within the same deployment.
Whether deploying a conference room, home theater, hotel AV network, or educational environment, modern systems require more than simple video extension.
The ability to return audio from the display is now essential.
The GPro EX70H2 provides a complete solution by combining:
into a single professional-grade extender.
For integrators looking to simplify installation and improve system performance, ARC-enabled HDMI extension offers a smarter approach to modern AV design.
