Features & Specs
Active Noise Cancellation (ANC)
Uses patented noise-reduction technology to dramatically lower unwanted interference traveling through your HDMI signal path, helping reveal cleaner gradients, steadier images, and more refined playback.
Jitter Elimination
Improves signal timing consistency downstream to preserve fine detail and reduce distortion—especially noticeable with high-resolution content and complex motion or shadow detail.
Full HDMI 2.1 Bandwidth Support
Designed to maintain modern HDMI performance, including 8K at 60Hz and 4K at 120Hz, while remaining backwards compatible with earlier HDMI standards.
TVS Surge Protection Built In
Adds an extra layer of protection against voltage spikes, surges, lightning-related events, and electrostatic discharge that can threaten sensitive AV components.
More Compatible Physical Design
The tapered, compact profile is made to fit around dense port clusters on TVs, receivers, processors, and projectors—reducing strain and improving real-world install success.
Installer-Friendly Extras
A built-in operational LED confirms function at a glance, and the included 15cm male-to-female HDMI extension helps solve clearance issues without compromising supported formats.
