Sescom SES-AUD-N-HDMI4K UHD 4K/2K HDMI Audio Inserter & HDMI Extender - B-Stock (US Adaptor Only)

A natural problem solver, the Sescom SES-AUD-N-HDMI4K is a simple solution for embedding stereo analog or multi channel surround external audio into your HDMI signal stream via a 3.5mm mini or Toslink connection. The Sescom HDMI audio inserter finds a home in digital signage advertising applications as well as smaller multicamera live production shoots where a single audio feed makes more sense than individual camera audio.

The unit supports HBR (high bit rate) Audio or Optical Toslink audio with sampling rates up to 192 khz! It is also HDCP 1.2 and DVI 1.0 compliant and supports [email protected]/30hz resolution and 3D signals! Avoid issues downstream with a CEC bypass function while you extend your 1080p, 8 bit, HDMI signal an additional 49 feet!

Note: For playback of 4Kx2K/3D HDMI source signals, a 4Kx2K/3D capable display and high speed HDMI cables are required.
