Description
The DA3-24-H is a 2×1:4 HDMI switcher and distribution amplifier designed to select and deliver one of two high-resolution sources to four identical displays. It accepts HDMI and USB-C inputs and supports native 4K60 video with HDR content where applicable. The unit equalizes and re-clocks the selected signal to maintain image integrity across multiple outputs.
Key features include support for 4K@60Hz 4:4:4 color, intelligent EDID handling, selectable HDCP authorization, and an analog audio output de-embedded from the incoming HDMI/USB-C signal. The device offers EDID lock and RGB-force options to ensure compatibility between sources and displays. A CEC mediator with flexible routing improves interoperability with consumer displays and AV sources.
Performance specs include an 18 Gbps maximum bandwidth and HDMI 2.0b compliance to support high-bandwidth 4K signals. The DA3-24-H handles HDCP 2.3 protected content and provides a max power output per HDMI port of 2.5W. Cooling is achieved with a low-noise fan inside a half-U 19 inch aluminum enclosure optimized for rack or ceiling installations.
Connectivity is comprehensive with one HDMI input, one USB-C input, four HDMI outputs plus a local HDMI output, a 1000BaseT RJ-45 Ethernet port for LAN control, and a 5-pin analog audio output. Control options include two RS-232 ports on 3-pin terminal blocks and IO on 2-pin terminal blocks. The unit supports secure web-UI communication via HTTPS and IT grade authentication including 802.1x.
Typical applications include corporate meeting rooms, education facilities, digital signage deployments, retail displays, and healthcare AV systems where distribution of a single 4K source to multiple displays is required. The selectable HDCP mode allows delivery of non-protected content when required while preventing protected content from being transmitted in non-HDCP mode. EDID management simplifies source and display interoperability in mixed AV ecosystems.
Installation is straightforward with a compact half-U form factor for side-by-side rack mounting or concealed ceiling placement. The included 20 VDC power adapter and clear control interfaces enable rapid integration into existing AV systems. Firmware and security features are designed for managed LAN environments, making the DA3-24-H suitable for professional AV integrators and IT-managed deployments.
