Product Overview

The Atlona AT-RON-442 is a 1×2 HDMI distribution amplifier in the Rondo Series, designed to split a single HDMI source to two displays simultaneously while maintaining 4K/UHD signal quality at 60 Hz with 4:4:4 chroma sampling and full HDR support. Built for commercial AV, professional visualization, and residential high-performance installations, this 4K HDR HDMI distribution amplifier is HDCP 2.2 compliant, supports HDMI data rates up to 18 Gbps, and includes EDID management to ensure source and display compatibility across varied AV system configurations. The AT-RON-442 fits into any installation requiring reliable 1×2 HDMI signal distribution with compatibility for HDR10, Dolby Vision at 60 Hz, and HLG formats, and its low-profile 1-inch-high enclosure simplifies rack or concealed mounting.

Product Description

The AT-RON-442 (Rondo 442) accepts a single HDMI input and distributes it to two HDMI outputs with full signal regeneration, supporting 4K/UHD resolutions at 60 Hz with 4:4:4 chroma subsampling for the highest color accuracy available in consumer and commercial HDMI delivery. The device handles the full HDMI 2.0 bandwidth of 18 Gbps, making it compatible with Ultra HD Blu-ray players, 4K media servers, gaming consoles, and PC sources outputting high-resolution graphics content. HDR support extends to HDR10, Dolby Vision at 60 Hz, and HLG (Hybrid Log-Gamma) for broadcast applications. EDID management allows the distribution amplifier to pass the connected display’s EDID to the source or substitute internally stored EDID data, ensuring the source device delivers the correct resolution and audio format for the AV system. Up to eight Rondo 442 and compatible Rondo Series units can be cascaded without signal degradation, enabling scalable HDMI signal distribution architectures for larger installations. Multi-channel audio formats including Dolby Atmos and DTS:X pass through transparently via HDMI at sample rates up to 192 kHz. Front panel LEDs indicate power and signal status on all ports. The 1-inch-high enclosure includes rack mount brackets and fits discreetly into rack spaces or concealed AV enclosures. Firmware updates are applied via the USB port in the field. The AT-RON-442 is well-suited for TV showrooms, professional AV visualization workflows, corporate digital signage distribution nodes, and dual-display conference room configurations where a single source must feed two screens reliably.

Frequently Asked Questions

Q: Can the AT-RON-442 split a 4K HDR source to two 4K HDR displays simultaneously?Yes. The AT-RON-442 distributes the HDMI input signal to both outputs simultaneously, passing HDR metadata including HDR10 and Dolby Vision at 60 Hz to both connected displays. Both displays must be capable of receiving and rendering the HDR signal for HDR output to be active on each.Q: What is the maximum HDMI cable length supported on the inputs and outputs?The AT-RON-442 supports HDMI cable runs up to 5 meters (15 feet) for 4K/UHD signals and up to 10 meters (30 feet) for 1080p signals on both the input and each output. For longer distances, an HDBaseT extender such as the AT-HDR-EX-70-2PS is recommended.Q: How many AT-RON-442 units can be cascaded together?Up to eight Rondo 442 and compatible Rondo Series distribution amplifiers can be cascaded without signal degradation, allowing expansion from a single 1×2 split to a larger distribution architecture as system requirements grow.Q: Does the AT-RON-442 support EDID management?Yes. The AT-RON-442 includes EDID management that allows the source to receive either the EDID of the connected display or an internally stored EDID from the unit. This ensures the source outputs a resolution and audio format that the AV system can support.Q: Is the AT-RON-442 rack-mountable?Yes. The unit ships with rack mount brackets and fits into standard equipment racks. Its 1-inch (26 mm) height allows installation in tight rack spaces or AV furniture enclosures alongside other signal management equipment.Q: What audio formats are passed through the AT-RON-442?The AT-RON-442 passes all HDMI audio formats including PCM stereo, LPCM 5.1 and 7.1, Dolby Atmos, DTS:X, Dolby TrueHD, DTS-HD Master Audio, Dolby Digital Plus, and DTS Digital Surround at sample rates up to 192 kHz and bit depths up to 24-bit.Q: Where can I purchase the AT-RON-442 and get integration support?The AT-RON-442 is available from Creation Networks, an authorized Atlona reseller.
