HDMI CEC Blocker for 4K UHD

The Boxwave adapter inserts between a source device and a display to stop unwanted CEC commands while passing video and audio. It suits owners of TV sticks, consoles or PCs who need clean control without the handshake interference that can switch inputs or power devices unexpectedly.

Male-to-female design fits tight spaces

The compact male-to-female layout plugs directly into an HDMI output, leaving the existing cable in place. Gold-plated connectors and a full metal jacket protect the 100 % pure copper core from corrosion and maintain signal integrity in confined gaps behind screens or AV racks.

Sustains 4K UHD with ARC and Ethernet

Rated for 10.2 Gbps at 340 MHz, the adapter carries 4K UHD, 48-bit deep colour and 7.1-channel audio through ARC while keeping the Ethernet channel active. The shielded construction preserves bandwidth and colour depth during long playback sessions without signal drop-out.

Questions about this item

Will the 10.2 Gbps bandwidth limit 4K HDR playback during long sessions?

The adapter supports 4K UHD at 10.2 Gbps, 340 MHz refresh rate and 48-bit deep colour, so sustained HDR streams stay within its rated throughput.

Does the all-metal housing and gold-plated connectors run hot or draw extra power when used continuously?

It is a passive CEC blocker with no active circuitry, so it adds no heat or power draw regardless of how long it stays connected.

Which HDMI source devices must I already have to use this CEC blocker with my soundbar?

Connect it between any HDMI source — Blu-ray player, game console, PC or set-top box — and the TV input; do not place it on the TV’s ARC/eARC port to the soundbar.
