Product Information
Connecting to every music source and yet compact enough for the tightest spaces, the Pro-Ject Uni Box S3 is the complete hub for your entire system.
One amp that does it all
From turntable to TIDAL Connect, TV to tuner radio, the Pro-Ject Uni Box S3 truly connects and plays it all. Based around a high quality amp, this mini Pro-Ject delivers smooth and detailed sound that belies its compact size. With wireless, digital and analogue inputs, it effortlessly connects to all of your components and, thanks to streaming technology by WiiM, delivers a vast range of streaming music options.
High quality sound – whatever the source
Although it’s packed with every type of music input option, the Uni Box S3 still puts sound quality first. The Class A/B amp features a dual mono design for perfectly balanced audio across the soundstage. The Cirrus Logic 24bit/192kHz DAC (Digital to Analogue Convertor) ensures your digital sources sparkle with detail and facilitates Hi-Res Audio playback.
Supports your favourite music streaming service
Built around the industry leading WiiM OS and using a dedicated Pro-Ject Home app, the Uni Box S3 has all your streaming music needs covered. The Home app supports a wide range of popular music streaming services, including Spotify, Amazon Music, TIDAL, Napster, Deezer, Qobuz and more. Internet radio and podcasts are also supported.
Spotify and TIDAL Connect
If you use Spotify and/or TIDAL apps, the WiiM Amp is compatible with their ‘Connect’ feature (premium account required). This lets you use the Spotify or TIDAL apps to take direct control of the amp, giving you a seamless experience as you switch between devices.
Build a multiroom system
The Pro-Ject Home app is far more than simply a music streamer, it also facilitates sophisticated multiroom playback. Add other Pro-Ject streamers around your home, and the app lets you play different music in each room, or the same music throughout. You can even stream music from connected devices, meaning that a vinyl played on your main system could be streamed to the home office or bedroom system.
Bluetooth connectivity
For a quick and easy wireless connection, the Uni Box S3 also supports Bluetooth 5.1. Simply pair with your smartphone, tablet, or even a Bluetooth turntable, and enjoy effortless wireless sound.
Connect your TV and other digital devices
As well as streaming capabilities, the Uni Box S3 connects to your TV and other digital devices. Use the HDMI ARC to connect to TV and enjoy soundbar-busting audio through your choice of speakers. There are also two optical digital inputs and one coaxial digital input, making this amp ideal for connecting to your games console, set-top T box, Blu-ray player or CD transport.
Plug in your turntable and other analogue devices
For the best sound from your analogue sources, the Uni Box S3 has a MM compatible phono input – perfect for connecting to most of Pro-Ject’s own turntables. There are a further two line level inputs that would suit a tuner, CD player or other line level device.
Headphone and variable output for subwoofer
If you fancy using smaller speakers or just crave extra bass, a variable output provides the perfect link to hook up to your choice of active subwoofer. Around the front, you’ll find a 6.35mm headphone socket for private listening.
Compact size
Despite packing in all that connectivity, the Uni Box S3 is incredibly space efficient. Around half the size of other separate amps, it’s perfect for rooms where space is at a premium, or as a desktop system. Choose between black and silver for the best match with your other components.
Hear the very best from all your music, digital or analogue, with the Pro-Ject Uni Box S3.
