AVPro Edge 8K 48 Gbps HDMI 4x4 Matrix Switcher

Product Overview

The AVPro Edge AC-MX-44X is an 8K-capable HDMI 2.1 4x4 matrix switcher built for high-end AV deployments that must support current and next-generation display technology. It routes any of four HDMI 2.1 sources to any or all of four outputs at full 48 Gbps bandwidth, covering 8K60, 4K120, and 4K60 at full 4:4:4 color depth. Designed for AV integrators specifying a future-proof 8K HDMI matrix switcher, it handles HDR10, Dolby Vision, and HLG with HDCP 2.3 compliance. The AC-MX-44X suits premium residential screening rooms, broadcast control rooms, and commercial AV environments where HDMI 2.1 bandwidth is a hard requirement.

Product Description

At 48 Gbps per port, the AC-MX-44X operates at the full rated bandwidth of the HDMI 2.1 specification, which means no downgrading of source signals to accommodate older switching hardware. All four inputs and four outputs are fully independent, allowing any-to-any routing with no bandwidth bottlenecks.

The switcher includes full EDID management, allowing individual EDID profiles to be assigned per input to ensure sources output at the correct resolution and format regardless of which display is selected. ARC and eARC audio return paths are supported, making it practical in installations where a connected AV receiver or soundbar needs to send audio back upstream. At 1U, it occupies minimal rack space for the bandwidth it provides.

Key Features

• HDMI 2.1 at 48 Gbps — full specification bandwidth on every input and output, with no signal downconversion.
• 8K60 and 4K120 Support — handles the highest resolution and frame rate combinations defined by HDMI 2.1.
• 4x4 Any-to-Any Routing — any source can be routed to any single output, multiple outputs, or all four outputs simultaneously.
• HDR10, Dolby Vision, and HLG — full HDR format pass-through without signal modification.
• HDCP 2.3 Compliance — handles the latest content protection requirements for premium video sources.
• ARC and eARC Support — bidirectional audio return channel for integration with AV receivers and soundbars.
• EDID Management — per-input EDID control ensures sources output at the correct format for each display.
• 1U Rack-Mountable — compact chassis fits standard equipment racks with minimal footprint.
• IP and RS-232 Control — compatible with major control system platforms.

Typical Applications

• Premium residential home theaters and screening rooms with 8K or high-frame-rate displays
• Broadcast control rooms requiring 8K or 4K120 source routing
• Esports and gaming venues distributing high-frame-rate content to multiple displays
• Corporate boardrooms and executive conference rooms with high-end display infrastructure
• Post-production suites routing between multiple 8K or 4K HDR monitors

Frequently Asked Questions

Does the AC-MX-44X require 8K displays to operate?

No. The matrix operates at whatever resolution the connected sources and displays negotiate. An 8K-capable matrix simply means it will not be a bottleneck when 8K sources and displays are used. It performs equally well with 4K60, 4K120, or lower-resolution signals.

Is eARC supported on all four outputs?

eARC capability depends on the specific output port and the connected display. Refer to AVPro Edge’s product documentation for per-port ARC/eARC assignment details, as this can vary by firmware version.

What HDMI cables are required to carry 48 Gbps?

Ultra High Speed HDMI cables certified to the HDMI 2.1 specification are required for 48 Gbps operation. Standard High Speed or Premium High Speed cables are not rated for this bandwidth and may result in signal errors at higher resolutions or frame rates.

Can routing presets be saved and recalled?

Yes. The AC-MX-44X supports routing preset storage and recall via the control interface, allowing common switching configurations to be triggered by a control system or manually via IP command.

Is the unit compatible with third-party control systems?

Yes. IP (TCP/IP) and RS-232 control interfaces are supported, making it compatible with Crestron, AMX, Control4, Savant, and similar platforms. AVPro Edge provides control documentation and drivers.
