Product Overview

The Lightware DA2HDMI-4K-Plus-A is a 2-output HDMI Distribution Amplifier with integrated audio embedding and de-embedding, designed for installations that require both video distribution and flexible audio routing at a single unit. It accepts a 4K HDMI source, distributes it to two HDMI outputs, and simultaneously provides analog audio de-embedding from the HDMI signal and analog audio embedding back into the HDMI outputs. HDCP support ensures compatibility with protected content sources.

Product Description

Audio flexibility is often the missing element in HDMI distribution deployments. Standard distribution amplifiers pass HDMI audio as-is, leaving installers unable to add room audio, route audio to a separate system, or replace HDMI audio with a local analog source. The DA2HDMI-4K-Plus-A solves this by combining distribution amplification with a built-in audio embedder/de-embedder. The de-embedding function extracts the audio from the incoming HDMI signal for routing to an amplifier, DSP, or recording system. The embedding function allows an analog audio source such as a wireless microphone system or room audio feed to be added to the HDMI signal sent to connected displays. This makes the unit particularly effective in rooms where the audio system and the AV display system need to share and exchange audio signals without additional audio processing hardware.

Key Features

• 1x HDMI input, 2x HDMI outputs for signal distribution
• 4K resolution support with HDCP compliance
• Analog audio de-embedding from HDMI input
• Analog audio embedding into HDMI outputs
• Eliminates need for separate audio embedder/de-embedder hardware
• Compact form factor suitable for rack or equipment room installation
• Suitable for installations requiring audio flexibility alongside HDMI distribution

Typical Applications

• Conference rooms where HDMI laptop audio must be sent to a room sound system
• Training rooms feeding a 4K source to two displays while extracting audio for amplification
• Boardrooms requiring a wireless microphone or room audio feed embedded into HDMI for recording
• Classrooms with separate AV and audio infrastructure needing integration at the distribution point
• Small-format broadcast or production setups requiring audio flexibility at a 2-output HDMI split point
• Hospitality AV installations with separate video and audio routing requirements

Frequently Asked Questions

Can the DA2HDMI-4K-Plus-A add audio from a microphone system to the HDMI signal?Yes. The analog audio embedding function allows an analog line-level audio signal such as the output from a wireless microphone receiver or room audio system to be embedded into the HDMI outputs. The audio level of the source should be at line level for proper embedding.Does de-embedding disable the audio on the HDMI outputs?The unit supports simultaneous de-embedding and embedding. The extracted audio and the embedded audio can operate concurrently, depending on the configuration. Consult the Lightware datasheet for the exact audio routing options available.Is this unit suitable for a 4K 60Hz source?The unit supports 4K resolution. Confirm the specific supported frame rates and color space in the Lightware product datasheet, or contact for detailed specifications.Does this work with HDCP-protected content from streaming devices?Yes. HDCP support is included, covering protected content sources. All connected displays must also support HDCP for protected content to be displayed correctly.Why would I choose a 2-output DA with audio embedding over a larger DA without it?If your installation requires audio flexibility extracting audio from HDMI for a room sound system, or adding a local audio source to the video feed the DA2HDMI-4K-Plus-A eliminates the need for a separate audio embedder/de-embedder device, reducing rack space, cost, and cabling complexity in two-display setups.Where can I purchase this unit?The DA2HDMI-4K-Plus-A is available at .
