48 Gbps Audio Down-mixer with Dante & Video Downscaling

Dante Enabled

Description

The AVPro Edge AC-AVDM-X is a 48 Gbps HDMI 2.1 audio down-mixer and video downscaler engineered for professional AV integration. It accepts multichannel audio bitstreams, including Dolby Atmos® and DTS:X®, embedded in HDMI 2.1 sources up to 8K/60 Hz, then decodes and downmixes them to 2-channel audio delivered simultaneously over analog L/R (RCA), S/PDIF optical (TOSLINK), and Dante/AES67 IP audio via a 100/1000 Mbps RJ45 port with PoE/PoE+ support.

The AC-AVDM-X is the direct evolution of the AC-AVDM-V3, replacing the coaxial S/PDIF output with a Dante network audio port and upgrading the HDMI bandwidth from 18 Gbps to 48 Gbps. A front-panel display with four navigation buttons (Up, Down, Select, Back) replaces the V3's rear-panel dip switches, giving installers intuitive on-unit control of EDID management, audio routing, downmix modes, and video scaling without requiring a laptop or external control system.

A USB Type-C port provides firmware updates and RS-232-style Telnet/SSH API control. The AC-AVDM-X is ideal for secondary zone audio in home theaters, commercial distributed audio systems, and any application requiring high-quality stereo extraction from immersive audio sources.

8K, 48Gbps Support (FRL 6): High bandwidth signaling supplies plenty of headroom for current sources and is fully prepared to handle 8K signals from any device using the AC-AVDM-X as a bridge. 

 

EDID Management and EDID Blend: 16 different EDID settings, including User Copy to retrieve the EDID from the connected display, enables systems with mixed era technologies to display the same content wherever desired. EDID Blend customization mixes audio and video EDIDs from two different signals for full flexibility and system compatibility.   

 

Full HDR Support: As HDR content evolves with dynamic metadata to enhance storytelling, AVPro Edge 8K devices ensure full fidelity passthrough of advanced HDR formats—including HDR10+, HLG, Dolby Vision, and IMAX Enhanced. These signals are repeated without degradation, with AVPro Edge’s image-handling circuitry delivering accurate tone mapping and full color volume to compatible displays.

 

Dante / AES67 Network Audio Output: Audio is distributed over standard Ethernet with no dedicated audio cable runs, and any Dante device on the network receives the downmix instantly.

 

High Frame Rate compatibility: The AC-AVDM-X supports 120fps with 4K or 1080p signals. 

 

Audio Downmixing: There is no need to set your source to 2-channel, no matter what kind of audio this device receives. Converting audio to 2-channel allows you to deliver Dolby Atmos sound to a home theater and 2-channel audio to a bedroom simultaneously.

 

Additional HDMI 2.1a Features: The AC‑AVDM‑X embraces key HDMI 2.1a features—Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Quick Media Switching (QMS), Quick Frame Transport (QFT), and Source‑Based Tone Mapping (SBTM).
