Audio Downmixer, Multi-channel -2CH

Ideal Use Cases

The AVPro Edge AC-AVDM-V3 is designed for HDMI distribution systems that need high-bandwidth video and flexible two-channel audio at the same time. It can deliver multichannel audio to a home theater while providing downmixed two-channel audio for a bedroom or another listening area, without requiring the source to be changed to two-channel output.

It is also suited to installations where an AVR needs high-bit-rate audio such as Dolby Atmos or DTS-X but should not manage the main HDR video path. Integrators can route video directly to a display or projector while supplying the required audio signal separately. One HDMI output can be downscaled for a 1080p display, allowing 4K and older displays to operate within the same system.

Why Choose This Model

The AC-AVDM-V3 combines 18Gbps HDMI video transmission, multichannel-to-stereo downmixing, audio extraction and output scaling in one compact device. Its HDMI configuration includes one Type A input and two Type A outputs, with scaling available on HDMI output 1. Extracted audio is available through unbalanced L/R stereo phono, coaxial SPDIF RCA and optical TOSLINK connections.

EDID management provides a choice of a preloaded 4K EDID or an EDID read from a connected display. This switch-based control helps match the source to the connected system without requiring a separate EDID-management device.

Installation and Integration

Connect the HDMI source to the single HDMI input, then route the two HDMI outputs to the required displays or AV equipment. HDMI output 1 can downscale a 4K source to 1080p when connected equipment does not support 4K. The other output can retain the higher-bandwidth signal for a compatible display or projector.

Analog stereo, coaxial SPDIF and optical TOSLINK outputs provide several ways to connect amplifiers and audio systems. A Micro USB connection is included, and power is supplied through a locking barrel-type connector. The supplied power specification is 100-240V AC at 50/60Hz input and 5V DC, 2A output.

Audio Return Channel support can carry local audio from compatible smart TV applications back to the headend for distribution through amplifiers. The unit measures 171.3 x 98.6 x 22.2 mm and weighs 0.3 lb, making it suitable for installations where equipment space is limited.

Performance Highlights

The video path supports resolutions up to 4K at 60Hz with 4:4:4 chroma and VESA resolutions up to DCI 4K at 4096 x 2160. Its 18Gbps bandwidth accommodates 4:4:4, 4:2:2 and 4:2:0 chroma formats. Deep Color support reaches up to 16-bit at 1080p and up to 12-bit at 4K.

Supported HDR formats include HDR10, HDR10+, HLG and Dolby Vision. Color handling covers YUV component and RGB, with color-space conversion support for Rec. 601, Rec. 709, BT2020, DCI and P3 D6500. HDCP 2.2 and earlier versions are supported for compatibility with protected HDMI sources and displays.

Total power consumption is rated at 6 watts maximum. The specified operating range is 23 to 125 degrees Fahrenheit, or -5 to 51 degrees Celsius, with a 5-90% relative humidity range without condensation.

What Makes It Different

The downmixer does not require the source to be manually set to two-channel audio. Supported downmixed formats include PCM 2.0, LPCM 5.1 and 7.1, Dolby Digital, Dolby Digital Plus with Atmos, Dolby TrueHD with Atmos, Dolby Atmos, DTS 5.1, DTS-HD Master Audio and DTS-X.

The HDMI pass-through path supports PCM 2.0, LPCM 5.1 and 7.1, Dolby Digital, DTS 5.1, Dolby Digital Plus with Atmos, Dolby TrueHD with Atmos, DTS-HD Master Audio and DTS-X. This combination supports installations that need advanced multichannel audio in one zone and stereo playback in another while maintaining the source’s multichannel configuration.

Final Assessment

The AC-AVDM-V3 brings together 4K60 HDR transmission, 18Gbps bandwidth, multichannel audio pass-through, two-channel downmixing, three extracted-audio connection types, EDID management, ARC and 1080p output scaling. It is a focused integration tool for systems combining current 4K displays, legacy 1080p equipment, AVRs and separate stereo audio zones.
