Crestron HD-DA-21x2 HDMI Distribution Amplifier Splitter Audio De-Embed 1080p

Crestron HD-DA-2 HDMI Distribution Amplifier with Audio De-Embed

A compact 1x2 HDMI distribution amplifier that splits a single HDMI source to two displays while simultaneously extracting the audio to S/PDIF and analog stereo outputs. Every unit is certified refurbished, fully tested in Melbourne and backed by a 12-month warranty from Reboot IT.

Key Benefits

• Splits one HDMI source to two displays. A single HDMI input is distributed to two identical HDMI outputs simultaneously, so one source can feed a pair of displays, projectors or signage screens at once without any loss of video quality.
• Audio de-embedding built in. The HD-DA-2 extracts the audio from the HDMI signal to both S/PDIF (coax and optical) and analog stereo outputs, so you can route sound to a separate amplifier or speaker system without a second cable run.
• 1080p60 Deep Color and 3D support. Video passes through at up to 1080p60 with Deep Color and 3D signal support, plus 1920x1200@60 for computer sources.
• Compact, easy-install form factor. A small standalone unit that tucks behind a display or inside an AV rack, powered by an included 24VDC power adapter.
• Certified refurbished and warranty backed. Every unit is tested by our Melbourne technicians and comes with a 12-month warranty from Reboot IT.
• Local Australian support. Backed by Reboot IT, supplying business-grade IT and AV equipment from Melbourne since 2001.

Performance in Use

In a boardroom or meeting room, the HD-DA-2 is commonly used to mirror a single laptop or media player feed to two displays at once — for example a presentation screen at the front of the room and a confidence monitor at the back — while the de-embedded audio is routed via S/PDIF to a separate amplifier feeding the room's ceiling speakers. Because the audio and video paths are split at the source, the room's sound system doesn't need to rely on a display's built-in speakers or a second HDMI run to an AV receiver.

In a classroom, the same distribution approach lets a single laptop or document camera feed both a projector and a secondary monitor for students seated further back, while the analog stereo output can connect directly into a classroom amplifier or PA system for announcements and video audio. It's a simple way to extend a single-source classroom AV setup without re-cabling the whole room.

For digital signage or venue AV integration, the HD-DA-2 is a practical way to duplicate a single content feed across two adjacent displays while independently feeding the audio into a background-music or paging system elsewhere in the venue. As a discontinued Crestron model it is well suited to expanding or replacing a unit in an existing HDMI distribution setup, and it is worth noting this model tops out at 1080p60 — for a 4K signal path, the HD-MD4X1-4K-E switcher is the newer alternative in the Crestron range.

Physically, the HD-DA-2 is designed to sit close to the source or the displays it feeds, with two HDMI outputs on one side and the S/PDIF and analog audio connections on the other, so installers can keep cable runs short in a rack or behind a screen. Because it treats video and audio as independent paths, an integrator can send the video output to two displays that are metres apart while running just a short audio cable to a nearby amplifier, rather than looping a full HDMI cable back to an AV receiver purely to recover sound. That flexibility is particularly useful in existing rooms where a receiver was never part of the original design, or where a display's built-in speakers simply aren't loud enough for the space. Combined with the compact chassis and included power adapter, the HD-DA-2 drops into most existing HDMI installs without any rewiring of the source or displays. It's also a sensible way to future-proof a room's audio routing: if the displays are ever swapped out or moved, the de-embedded S/PDIF and analog feeds keep working from the same source without any change to the sound system.

Frequently Asked Questions

Does the HD-DA-2 support 4K?

No. This model supports up to 1080p60 with Deep Color and 3D, plus 1920x1200@60 for computer sources. It is not the same as the 4K-capable HD-MD4X1-4K-E.

What's the maximum computer resolution supported?

1920x1200@60 for computer sources, alongside 1080p60 for standard video content.

Does it extract audio from the HDMI signal?

Yes. It de-embeds audio to both S/PDIF (coax and optical) and analog stereo outputs at the same time as passing video through to the two HDMI outputs.

Is HDCP 2.2 supported?

Crestron hasn't published an HDCP version for this model, so we can't confirm a specific version — check compatibility with your source and display if HDCP 2.2 is a hard requirement.

Is the power adapter included?

Yes. Reboot IT supplies the 24VDC power adapter with every unit.

Is shipping free?

Shipping costs apply based on size and destination — rates are calculated at checkout.

Is it a current Crestron product?

No, this is a discontinued Crestron model, so it's best suited to expanding or replacing a unit in an existing HDMI distribution installation.
