Wireless surround

Now you can build a complete, wireless surround system with DALI active wireless speakers. Add the HDMI expansion module to your SOUND HUB for HDMI ARC and eARC connectivity, allowing you to stream surround sound wirelessly from your TV. Both Dolby and DTS formats are supported, in configurations up to 7.1 channels.


Zero Loss volume control is handled at the end of the digital signal chain – in the speakers themselves. This ensures that volume adjustment does not result in data loss through truncation of the digital word length.

Low latency

The total system latency is extremely low at under 15mS, meaning that the signal delay from input to speaker is so low, that you will experience no loss of lip-sync in audio-visual systems.


Adds wireless surround sound to the DALI SOUND HUB.

This ARC/eARC compatible module codes DOLBY and DTS surround up to 7.1 and lets you mix and match speakers from the OBERON C, CALLISTO C, and RUBICON C series.


Build a complete active wireless surround system without compromising great sound. At the centre of the DALI wireless surround stands the DALI SOUND HUB wireless audio preamplifier.

The signal is transmitted wirelessly with up to 24-bit/96kHz resolution without lag and loss in sound quality.
