Lightware DA2HDMI-4K-Plus HDMI Distribution Amplifier with HDCP - 91320007

Product Overview

The Lightware DA2HDMI-4K-Plus (part number 91320007) is a 2-output HDMI distribution amplifier with full HDCP 2.2 compliance, designed for professional AV environments where a single 4K source must drive two displays simultaneously. It delivers identical, reclocked signals to both outputs while providing comprehensive EDID management — making it a reliable building block for control rooms, dual-screen conference rooms, and digital signage installations.

Product Description

The DA2HDMI-4K-Plus supports 18 Gbps HDMI 2.0 bandwidth with 4K/60Hz at 4:4:4 chroma subsampling. Signal reclocking on both output ports regenerates a clean clock, preventing jitter-induced artifacts when driving displays over longer cable runs. The unit handles HDCP 2.2 authentication independently on each output, so protected content plays correctly regardless of whether one or both connected displays are HDCP 2.2 capable.

EDID management allows the integrator to store and emulate custom EDID data, ensuring the source device always sees a consistent downstream capability profile — critical in systems where displays may be swapped or powered off without affecting the source output. Available from Creation Networks.

Frequently Asked Questions

Can one display be HDCP 2.2 and the other HDCP 1.4?

Yes. The DA2HDMI-4K-Plus authenticates HDCP independently on each output port, so a mix of HDCP 2.2 and 1.4 displays is supported. Note that HDCP 2.2 protected content will only display on the HDCP 2.2 capable output.

What happens if one connected display is turned off?

EDID emulation ensures the source device continues to see a valid downstream device on both outputs. The source maintains its signal output and the active display continues to receive content uninterrupted.

Does it support audio formats like Dolby Atmos?

Yes. Audio carried in the HDMI 2.0 signal — including Dolby Atmos, DTS:X, and multi-channel PCM — passes through to both outputs without modification.

Is the DA2HDMI-4K-Plus rack-mountable?

Yes. It ships with mounting brackets for standard 19-inch rack installation, and can also be used as a desktop unit in smaller setups.

What is the maximum cable length I can use on the outputs?

With quality 28 AWG passive cables, 4K/60Hz typically reaches 5 meters reliably. For longer runs, use active HDMI cables or add a fiber HDMI extender downstream.

Is control via RS-232 or Ethernet supported?

Yes. The unit supports external control via RS-232 and Ethernet, enabling integration with third-party control systems for remote monitoring and EDID management.
