The Atlona AT-HDR-M2C is a specialized audio processing device designed to extract, downmix, and convert multi-channel digital audio from high-definition video sources into a two-channel analog stereo format. This unit addresses a common integration challenge in AV systems where a source—such as a 4K Blu-ray player, media server, or gaming console outputting HDMI with multi-channel audio (like Dolby Digital, DTS, or uncompressed PCM)—needs to connect to an audio system that only accepts standard analog stereo inputs. It extracts the audio from the HDMI signal, downmixes the multi-channel stream to a high-quality stereo signal, and outputs it via balanced XLR or unbalanced RCA connectors, while simultaneously passing through the native 4K/UHD HDR video untouched via its HDMI output.

The converter supports the latest HDMI 2.0b specifications with HDCP 2.2 compliance, ensuring compatibility with 4K content at 60 Hz, High Dynamic Range (HDR10 and HLG), and wide color gamuts (Rec. 2020). Its audio processing capabilities include support for high-bitrate audio formats and the ability to handle complex multi-channel codecs, intelligently downmixing them to preserve dialogue and key sonic elements in the resulting stereo mix. The device is housed in a compact, metal enclosure suitable for discreet installation behind displays or within equipment racks and is powered via an included external power adapter.

Ideal for commercial installations such as boardrooms, classrooms, digital signage, and home theaters with legacy stereo audio systems, the AT-HDR-M2C provides a seamless bridge between modern video sources and traditional analog audio infrastructure. By ensuring flawless audio extraction and downmixing without affecting video quality, it simplifies system design and enhances compatibility in hybrid digital-analog environments.
