Send the picture out. Bring TV sound back.
Place the source equipment where it belongs and keep the viewing area uncluttered. 4KEX70-ARC-H2 carries HDMI video and embedded audio between a matched transmitter and receiver over Cat6a / Cat7 for the specified 4K maximum, making longer installed connections easier to plan.

Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Bring the picture to the right place
Use the transmitter beside the source and the receiver beside the remote display. The specified video limit is 4K60, 4:4:4; distance depends on cable type and the selected signal. 4K: 40m · 1080p: 70m is the relevant planning limit for this model.
Keep the remote end useful
ARC and optical return audio help connect a TV to audio equipment located near the source. Forward HDMI audio and return audio have different format limits: ARC/optical should not be treated as a lossless eARC path.
Plan the cable and power together
Use Cat6a / Cat7 for the specified 4K maximum. One supplied adapter powers both ends through bidirectional PoC. Test the complete link, including short video cables at each end, before pulling cable through walls or securing equipment.
Make sure it fits your setup.
The correct cable
Cat6a / Cat7 for the specified 4K maximum. Use a properly terminated, continuous run within the documented distance.
Direct link required
Connect the labelled extender ports directly to one another. An RJ45 connector does not make this link compatible with a normal Ethernet switch.
Power and peripherals
One supplied adapter powers both ends through bidirectional PoC. This model is for video/audio extension; it is not a general USB extender.
From unboxing to connected.
Plan the link
Match the cable type, total length and required resolution to this model’s limits.
Connect both ends
Put the transmitter at the source and the receiver at the display or USB devices.
Power the kit
Use the power connection specified for this model; then check the link indicators.
Test before installing
Confirm video, sound and any USB/control functions before securing the cable run.

A little clarity before you buy.
Can I connect it through a network switch?
No. This model needs the specified direct link between its transmitter and receiver. Choose a documented AV-over-IP model for switched-network distribution.
Is the maximum distance the same at every resolution?
4K: 40m · 1080p: 70m. Follow the model documentation for cable category and signal-specific limits.
What should I check if there is no picture?
Check input/output direction, power indicators and cable termination. Try a lower source resolution and a short known-good link before testing the installed run.
