The DALI Sound Hub features an extended range of digital and analogue inputs combined with an auto source sensing system. The Sound Hub automatically activates the right input the moment you start playing music or turn on your TV – so you can just sit back and enjoy exquisite audio.

The front-facing volume knob embeds an LED display, which combines Hi-Fi tradition with convenience. The LED display shows the current audio source as well as the volume level, and you can even adjust the light intensity of the display. This is supported by a light display on top of the Sound Hub, which indicates the location of the speakers in the pairing process.

We have made the setup simple, so you only have to worry about adjusting the volume, which can be done via a multitude of options. E.g. on the Sound Hub, by using the included Bluetooth remote, via your smart device (depends on the brand) or directly via the touch panels built atop of the CALLISTO C range.

MQA Certified

The DALI CALLISTO C, RUBICON C and OBERON C systems are MQA Certified. By adding the DALI BluOS NPM-1 module to your Sound Hub, you can now take advantage of the ever-growing catalogue of studio master recordings that have been encoded into MQA and streamed on services like Tidal.

Quick Setup

Setting up a Hi-Fi system couldn't be easier. You literally only have to connect the power chord to the CALLISTO speakers and the Sound Hub followed by pushing the CONNECT button. Voilà and you are ready to stream from your phone or music server.

Touch Sensitive Volume

The touch sensitive panel atop the CALLISTO C speaker cabinet lets you control the volume at the touch of your finger tip. The included Bluetooth remote & the Sound Hub's volume knob gets the job done just as easily. Regardless of your approach, the actual volume change is done at the very end of the signal chain.

Mulitiple Sources

The Sound Hub supports a list of different sources: Bluetooth (AAC & Apt-X HD), Analogue (RCA & Mini Jack), Coaxial RCA, 2 x Optical (Audio & TV), USB output (Google Chromecast Audio) and 2 x modular expansion ports (e.g. BluOS).

BluOS expansion

Benefit from Bluesound’s incredible BluOS hi-res multi-room platform by adding the optional BluOS module. BluOS is devised by audiophiles for audiophiles to deliver the best digital sound quality imaginable throughout your house. Access almost any streaming service via the free BluOS app.


The wireless connection between the Sound Hub and the speakers is an extremely stable digital connection, made on either the 2.4 GHz or the 5.8 GHz band depending on location and quality of the connection. The proprietary 30 bit protocol transfers an uncompressed I2S audio signal in 24 bit 96 kHz, utilising the remaining bits to control volume, speaker ID and other control data. Because it works on a less trafficked band, and the protocol is specially designed for transporting an audio signal, the connection is highly stable introducing next to no packet loss.

The protocol uses forward error correction to remove the result of packet loss should they occur. The high bandwidth low latency protocol functions as a point to multipoint connection. This allows for multiple speakers to connect to the same stereo signal. With latency below 25 ms, sync between video and audio from a movie or TV source is obtained well within conventionally acceptable limits.

MQA Certified

The wireless CALLISTO C, RUBICON C and OBERON C systems are now MQA Certified by MQA Ltd. This applies to all the products in the mentioned ranges, when the optional BluOS NPM-1 plug-in module is installed.

MQA’s award-winning technology captures 100% of the original recording and packages it in a file small enough to stream. When streamed by BluOS through the Sound Hub's wireless no-loss fully digital audio transfer, every little detail in the MQA file will find its way to the ear of the listener.

BluOS was an early adopter of the MQA technology and the RUBICON C, CALLISTO C and OBERON C systems now join nearly 30 other BluOS Enabled products by NAD Electronics and Bluesound.

Already acquired DALI Sound Hubs, which includes a BluOS NPM-1 module, will automatically be updated with the MQA technology.
