AVPro Edge AC-AXION-IN-AVDM Dual 18Gbps HDMI input ports

Product Overview

The AVPro Edge AC-AXION-IN-AVDM is a dual-input HDMI input card for the AC-AXION-X modular matrix chassis, providing two independent 18Gbps HDMI 2.0 input channels with built-in audio downmixing (AVDM) in a single card slot. This is a chassis expansion card, not a standalone product — it requires an AC-AXION-X chassis to function. Designed for high-end residential and commercial AV installations, the AVDM input card allows integrators to route 4K HDMI sources — including Dolby Atmos and Dolby Vision content — through the AXION-X matrix while simultaneously downmixing multi-channel audio to a 2-channel stereo signal for zones or amplifiers that do not support surround formats.

Product Description

The AC-AXION-X is a modular, slot-based matrix switcher chassis that allows integrators to configure input and output card combinations to match the specific source and display count of each installation. The AC-AXION-IN-AVDM fills one input slot of that chassis with two HDMI 2.0 inputs — each supporting signals up to 18Gbps, covering 4K60 4:4:4, HDR10, Dolby Vision, and Dolby Atmos — plus two mirrored HDMI loop outputs for local monitoring or confidence display at the rack. The built-in AVDM (audio downmix) engine processes 8-channel or greater audio from the HDMI source and converts it to a 2-channel stereo output, which can be independently routed to amplifiers, audio zones, or A/V receivers that handle only stereo input. This eliminates the need for a separate audio matrix or DSP for downmix duties in most whole-home or commercial installations. Each card occupies one slot in the AXION-X chassis, and multiple cards can be installed to match project requirements — two sources per card slot.

Key Features

• Dual HDMI 2.0 Inputs — Two independent 18Gbps HDMI input channels per card, supporting 4K60 4:4:4, HDR10, Dolby Vision, and Dolby Atmos sources.
• Built-In Audio Downmixing (AVDM) — Converts 8+ channel surround audio (Dolby Atmos, DTS:X) to 2-channel stereo output for zone amplifiers and distributed audio systems.
• Dual HDMI Loop Outputs — Each input includes a mirrored HDMI loop output for local rack monitoring or confidence display.
• 18Gbps Per Input — Full HDMI 2.0 bandwidth supports the highest-quality 4K signals without compression or downsampling.
• Modular Chassis Card — Designed for the AC-AXION-X chassis; requires chassis for operation. Not a standalone device.
• Two Sources Per Card Slot — Maximizes chassis density by providing two input channels from a single card slot.
• High-End Signal Support — Handles HDMI 2.0 signals including 4K, HDR, Dolby Vision, and Dolby Atmos without external conversion.
• Configurable Matrix Integration — Works within the AXION-X routing matrix to distribute each source to any output card in the chassis.

Typical Applications

• Luxury residential AV installations using the AC-AXION-X chassis for whole-home 4K matrix distribution with per-zone audio downmixing
• High-end commercial installations requiring modular, expandable matrix switching with Dolby Atmos source support
• Home theater and media room systems where surround audio sources must be distributed to stereo-only secondary zones
• Integrators building custom matrix switcher configurations specifying exact input counts for each project

Frequently Asked Questions

Does this product work on its own, or does it require a chassis?

This is an expansion card and requires the AVPro Edge AC-AXION-X modular matrix chassis to function. It cannot be used as a standalone device. If you do not already have an AC-AXION-X chassis, you will need to purchase one separately. Contact Creation Networks for complete AXION-X system design assistance.

How many sources does one card provide?

Each AC-AXION-IN-AVDM card provides two independent HDMI input channels, occupying a single input slot in the AXION-X chassis. To add more sources, additional input cards can be installed in remaining chassis slots up to the chassis capacity.

What does the audio downmixing (AVDM) feature do?

The AVDM engine takes an 8-channel or higher audio signal — such as Dolby Atmos or DTS:X — from the HDMI source and converts it to a 2-channel stereo audio output. This stereo output can be routed independently through the matrix to amplifiers or audio zones that accept only stereo input, without affecting the full-quality audio on the main HDMI video output path.

What is the HDMI loop output used for?

Each input on the card has a corresponding HDMI loop output that mirrors the incoming source signal. This allows a local display or confidence monitor to be connected directly at the rack or equipment closet for signal verification without consuming a matrix output port.

What HDMI signal formats are supported?

The card handles all HDMI 2.0 signal formats up to 18Gbps, including 4K60 4:4:4, HDR10, Dolby Vision, Dolby Atmos, DTS:X, and standard LPCM audio. It is designed to handle any HDMI 2.0 source without requiring manual configuration of signal format.
