Cyrus - ONE Cast - Integrated Smart Amplifier

With ONE Cast you can stream music in high-quality directly from your phone using Spotify, Deezer, Amazon Music, Apple Music, Qobuz, Tidal – in fact, almost any streaming service over Wi-Fi. If you have voice assistant smart speakers on the same Wi-Fi network, you can use voice commands to send music directly to your ONE Cast smart amplifier or even set as part of a group for true multi-room audio.

The ONE Cast

As the center of your new smart home audio system, ONE Cast will connect directly to virtually anything that produces audio. From mobile phones over Wi-Fi, laptops through USB, games consoles, record players and radio stations over the internet. You can even connect your Smart TV to ONE Cast using HDMI. It even features a class-leading headphone amplifier for late-night listening.

The Cyrus ONE Cast is arguably the most innovative stereo amplifier available today. Boasting 100 watts per channel and using bleeding-edge technology developed entirely at our Cambridge headquarters, this smart amplifier is capable of driving any loudspeakers with unerring ease from anywhere in the house.

ONE Cast doesn’t need a separate app.

Just like a Smart Speaker, you simply connect directly to ONE Cast using Spotify, Apple Music, Tidal, Qobuz, Deezer, or whichever streaming service you use on your phone. Two taps and the music that was on your phone is now amazing your senses, now that’s one smart amplifier.

Just open your chosen music streaming service, play some music and select the ‘now playing’ screen. Now you simply connect to ONE Cast just as you would with any other smart speaker on the market. No need for a smart audio app, ONE Cast takes care of that for you.

Use voice control through your 'Smart speaker'

If you have a smart speaker (Apple Homepod, Amazon Echo/dot or Google Home) on the same wifi network, you can use voice commands to send music to your ONE Cast. IF it’s in standby, it will automatically wake up and start playing.
