Atlona HDR-Compatible HDMI Audio De-Embedder and Downmixer

Atlona just launched the AT-HDR-M2C-QUAD — a multi-channel audio converter that extracts, decodes and downmixes multi-channel PCM, Dolby and DTS audio from four HDMI sources simultaneously, including HDR signals.

The AT-HDR-M2C includes HDMI inputs in a single, 1U, rack-mountable unit and enables integration of multiple HDMI audio sources into whole-house or distributed audio system. TOSLINK digital and unbalanced analog audio outputs deliver stereo downmixed audio to displays, multi-zone audio amplifiers and other audio systems, while the ability to pass through each HDMI input to a corresponding HDMI output without downmixing.

The AT-HDR-M2C-QUAD supports HDMI signals up to 4K/UHD at 60 Hz with 4:4:4 chroma sampling with data rates up to 18 Gbps and can de-embed HDMI audio with or without being connected to a display or other HDMI destination. HDCP 2.2 compliant and capable of handling all video resolutions, audio formats and color spaces encompassed by the HDMI 2.0b specification, the new audio converter is also compatible with High Dynamic Range formats including 4K HDR10 and Dolby Vision at 60 Hz.

Integrated audio volume, bass and treble adjustments eliminate the need for an external DSP to change gain and tonesettings, and can be controlled over an IP network through the device’s built-in web interface, the Atlona Management System (AMS 2.0) software, Atlona’s Velocity IP-based AV control platform or third-party control systems.
