Atlona unveils HDMI audio de-embedder and downmixer

Atlona has announced the launch of its quad-input, HDR-compatible HDMI audio de-embedder and downmixer, the ‘AT-HDR-M2C-QUAD.’

Introduced to support multi-channel audio extraction, decoding and stereo downmixing for four HDMI sources simultaneously, the Atlona AT-HDR-M2C-QUAD convertor is suited to both residential and commercial environments.

The HDR-M2C-QUAD can extract, decode, and downmix multi-channel PCM, Dolby, and DTS audio from multiple HDMI sources, including HDR-enhanced 4K/UHD signals. It incorporates the downmixing capabilities of Atlona’s AT-HDR-M2C to four simultaneous HDMI inputs in a single, 1U, rack-mountable unit, and according to Atlona allows for “easy integration of multiple HDMI audio sources into whole-house and other distributed audio systems.”

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 enables integration with Atlona matrix switchers (e.g. the AT-HDR-H2H series and AT-UHD-PRO family).

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 colour spaces encompassed by the HDMI 2.0b specification, the audio converter is also compatible with High Dynamic Range formats including 4K HDR10 and Dolby Vision at 60 Hz.

Audio volume, bass, and treble adjustments are integrated (removing the need for an external DSP to change gain and tone settings), and can be controlled via IP on 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.

The HDR-M2C-QUAD is now shipping and comes with a 10-year product warranty.

Atlona will showcase its latest de-embedder and downmixer at booth #3015 at CEDIA 2018 in California. This year’s event takes place from the 6 to 8 September, 2018 at the San Diego Convention Centre.
