OpenAudio has introduced real-time media metadata to its HOLO-WHAS multi-zone audio range, enhancing its KNX integration. This update is now available in Australia and New Zealand through distributor AVOZ.
Enhanced KNX Integration for Detailed Audio Information
The update expands OpenAudio’s KNX capabilities beyond basic audio commands. Compatible KNX control systems can now display detailed information about the content being played, including track title, artist, album, playback status, and progress.
Previously, the KNX implementation focused on four core functions: mute, volume, source selection, and audio routing. The new metadata layer allows KNX touch panels and visualisation systems to present detailed audio information rather than simple control options alone.
Bridging a Gap in Building Automation
The update addresses a longstanding gap in building automation, where lighting, climate, shading, and security often offer deeper visualisation than distributed audio. In many installations, users could adjust volume or switch sources, but could not view meaningful media information from the same interface.
According to Darren Ma, PhD, Business Development Director at OpenAudio, “By bringing metadata directly into the KNX ecosystem, we are helping create a more seamless and informative user experience.”
HOLO-WHAS Platform Features and Applications
The HOLO-WHAS platform combines several audio functions in one unit, including streaming, amplification, matrix routing, DSP processing, and automation integration. The range is built around a 16-channel design, supporting eight independent audio zones and eight streaming sources.

The hardware is aimed at residential, hospitality, and commercial settings where audio is managed across multiple rooms or areas. The system can route multiple sources independently to different zones and supports several routing arrangements across a property.
The HOLO-WHAS Plus model includes 16 x 100W of amplification for a total output of 1,600W. Depending on the model, the range offers up to 100W or 200W per channel.
Streaming support includes Qobuz Connect, AirPlay 2, Spotify Connect, DLNA, and Bluetooth. Physical inputs include RCA, SPDIF, USB, and HDMI ARC. OpenAudio also supports 1-to-N, M-to-1, and M-to-N routing, allowing flexible source and zone configurations.
For larger projects, multiple OpenAudio units can be used within a wider centralised system. Each device supports eight zones and can be cascaded for larger installations.
AVOZ has been appointed exclusive distributor for OpenAudio in Australia and New Zealand, giving it responsibility for bringing the HOLO-WHAS range and its KNX integration to the local custom installation and automation market. The latest KNX metadata support is delivered through the current OpenAudio firmware release.
