Universal Audio De-embedder for 4K/UHD Signals

This product is the commercial version of the AT-HD-M2C. In commercial applications where audio is provided by an HDMI source, integrators need an easy solution to extract balanced, +4 dBu, two-channel or monaural audio for professional sound reinforcement systems while maintaining full 4K/UHD video signal integrity for video switching and distribution systems. Integrated control reduces total cost in simple systems potentially eliminating a DSP or other volume control device.

The AT-UHD-M2C-BAL is ideal for use in training or meeting spaces that require audio from PCs or Blu-ray players to be routed to a distributed speaker system. The converter is placed in line between the source and the HDBaseT transmitter or switcher in order to provide a feed to both the sound and video systems.
