Atlona 4K HDR 4x4 HDMI Matrix Switcher - AT-HDR-H2H-44MA

Product Overview

The Atlona AT-HDR-H2H-44MA is a 4x4 HDMI matrix switcher supporting 4K/UHD video at 60 Hz with 4:4:4 chroma sampling and full HDR format compatibility, including HDR10 and Dolby Vision at 60 Hz. Designed for residential custom integration and commercial AV applications, it provides reliable any-input-to-any-output routing of HDMI signals at bandwidths up to 18 Gbps with HDCP 2.2 compliance. As a 4K HDR HDMI matrix switcher for home theaters and AV distribution systems, this unit is also well suited as a commercial 4x4 HDMI switcher for TV showrooms and visualization environments, and as a rack-mount HDMI matrix switcher with CEC display control for multi-room AV systems.

Product Description

The Atlona AT-HDR-H2H-44MA is a 4-input, 4-output matrix switcher designed exclusively for HDMI signals and built to handle the demands of 4K/UHD and HDR content distribution. It is part of Atlona's 4K HDR product family and supports video resolutions from standard definition through 4K/UHD at 60 Hz, with chroma sampling up to 4:4:4, color depth up to 12-bit, and HDMI data rates up to 18 Gbps. HDR format support includes HDR10 and Dolby Vision at 60 Hz as well as HLG (Hybrid Log-Gamma) for 60p HDR broadcast services. HDCP 2.2 compliance ensures protected content passes correctly between sources and displays. EDID management allows the matrix to present the correct EDID to each source, ensuring audio formats and video resolutions are negotiated properly across the system. HDCP management can be selectively disengaged to allow non-protected PC output to reach non-HDCP displays, streaming devices, or teleconference systems without blocking the signal. Each of the four HDMI inputs has a paired unbalanced analog audio output for de-embedding two-channel PCM audio and routing it to a whole-house or commercial audio distribution system. CEC display control can be sent independently to each of the four outputs, enabling individual power on/off of connected displays via IP or RS-232 commands. The front panel includes physical buttons and an LCD menu display for direct matrix routing, configuration, and troubleshooting without requiring a connected control system. Control interfaces include TCP/IP Ethernet, RS-232, and IR, with compatibility for Atlona Velocity and third-party control systems including AMX, Crestron, Control4, and Savant. Firmware can be updated in the field via the built-in web GUI, Velocity Device Manager, or the front USB port. The 1U, full-rack-width enclosure ships with rack mounting brackets and an external universal power supply. The AT-HDR-H2H-44MA is available at creationnetworks.net.

Key Features

• 4x4 HDMI Matrix Switching — Routes any of four HDMI sources to any combination of four HDMI outputs with full non-blocking matrix capability and front panel routing control.
• 4K/UHD @ 60 Hz with 4:4:4 — Supports 4K/UHD resolutions at 60 Hz with full 4:4:4 chroma sampling and HDMI data rates up to 18 Gbps for maximum signal fidelity.
• HDR10, Dolby Vision, and HLG Support — Compatible with HDR10 and Dolby Vision at 60 Hz and HLG for 60p HDR broadcast workflows, future-proofing installations for current and emerging HDR content.
• HDCP 2.2 Compliant — Passes the latest HDCP-protected content from UHD Blu-ray players, streaming devices, and other HDCP 2.2 sources to compliant displays.
• Independent CEC Display Control per Output — Sends CEC power on/off commands independently to each of the four connected displays, triggered via IP or RS-232 control commands.
• HDMI Audio De-embedding per Input — Each HDMI input has a paired unbalanced analog audio output (RCA) for extracting two-channel PCM audio to feed a separate audio distribution or amplification system.
• EDID and HDCP Management — Manages EDID negotiation from connected displays or internal EDID tables; HDCP compliance can be selectively disengaged for non-protected sources and non-compliant endpoints.
• TCP/IP, RS-232, and IR Control — Multiple control interfaces support Atlona Velocity and major third-party control platforms including AMX, Crestron, Control4, and Savant.
• Front Panel Controls and LCD Display — Physical buttons and LCD menu allow direct matrix routing configuration, monitoring, and troubleshooting at the device without a connected control system.
• Multi-Channel Audio Pass-Through — Passes PCM 2.0, LPCM 5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS Digital Surround, DTS-HD Master Audio, and DTS:X formats through HDMI outputs.
• Field-Updatable Firmware — Firmware updates via web GUI, Velocity Device Manager, or front panel USB port reduce maintenance time and support remote updates.
• 1U Full-Rack Enclosure — Rack-mountable 1U form factor with included 19-inch rack brackets for clean integration into professional AV racks.

Typical Applications

• Custom residential home theater and whole-home AV distribution with UHD and HDR sources
• TV showrooms demonstrating 4K and HDR content quality to multiple displays simultaneously
• Professional visualization and simulation environments requiring high-fidelity 4K graphics distribution
• Commercial boardrooms and conference centers with multiple display zones and independent source routing
• Broadcast and production facilities requiring reliable 4K HDR HDMI signal routing
• Education and training facilities with multiple displays requiring independent content control
• Custom AV integrations where existing HDMI infrastructure must be preserved without HDBaseT conversion

Frequently Asked Questions

Q: What HDR formats does the AT-HDR-H2H-44MA support?

The AT-HDR-H2H-44MA supports HDR10 at 60 Hz, Dolby Vision at 60 Hz, and HLG (Hybrid Log-Gamma), which is used for 60p HDR broadcast services. This makes it compatible with current Ultra HD Blu-ray players, HDR streaming sources, and broadcast equipment.

Q: Can the AT-HDR-H2H-44MA de-embed multi-channel Dolby or DTS audio?

The unit de-embeds two-channel PCM audio only. For applications requiring extraction and downmixing of Dolby or DTS multi-channel audio formats, Atlona recommends pairing the AT-HDR-H2H-44MA with the AT-HDR-M2C 4K HDR Multi-Channel Digital to Two-Channel Audio Converter.

Q: Does CEC control work with all connected displays?

CEC functionality depends on the display manufacturer's implementation. Atlona has confirmed proper operation with many current Samsung, Panasonic, Sony, and LG televisions that follow the CEC command structure from HDMI 1.2a and support the power-off command from a source device. Older televisions and models using proprietary CEC implementations may not respond correctly.

Q: What control systems are compatible with the AT-HDR-H2H-44MA?

The AT-HDR-H2H-44MA includes driver support for AMX, Crestron, Control4, Savant, Clare Controls, Elan, Neets, RTI, Universal Remote Control, and Vantage. It is also compatible with Atlona Velocity and Velocity Device Manager for network-based configuration and management.

Q: Can HDCP be disabled on specific outputs?

Yes. HDCP compliance can be selectively disengaged through Velocity or another control system for outputs connected to non-HDCP endpoints such as teleconference codecs, streaming encoders, or older displays. Note that disabling HDCP only allows non-protected content to pass; HDCP-protected content will not transmit to non-compliant endpoints.

Q: What is the maximum HDMI cable length supported at 4K?

The AT-HDR-H2H-44MA supports passive HDMI cables up to 15 feet (5 meters) at 4K/UHD resolutions and up to 30 feet (10 meters) at 1080p. For longer runs, Atlona HDBaseT extenders such as the AT-HDR-EX-70-2PS or AT-HDR-EX-100CEA-KIT can be used in conjunction with this matrix switcher.

Q: Is the AT-HDR-H2H-44MA compatible with Velocity Device Manager?

Yes. The AT-HDR-H2H-44MA is an IP-controllable device that integrates with Atlona Velocity Device Manager, the free network software platform for configuring, managing, updating firmware, and monitoring Atlona devices across a LAN, WAN, or VPN from a web browser.
