Pro-ject audio Uni Box S3 Black
THE MASTER OF ANALOGUE & DIGITAL
The Uni Box S3 masterfully bridges the worlds of analogue and streaming. Your analogue sources - like turntables - are not digitized, preserving their rich and lifelike sonic character. With a fully analogue pre- & and power amp design, every nuance of your music is delivered with breathtaking punch and dynamic precision. At Pro-Ject Audio Systems, our mastery of analogue hardware design allows us to craft an astonishingly powerful amplifier within the sleek, compact aluminium case of the Uni Box S3. All this power remains usable entirely without a mobile app or the need to constantly update software.
MARKET LEADING STREAMING
Partnering with WiiM, the Uni Box S3 streaming technology is powered by the industry leading WiiM OS™. The Cirrus Logic CS4344 DAC offers a high quality resolution of up to 24bit and 192kHz.
With the Pro-Ject Home app you control the streaming options on input 8 - the streaming input. Setting up the WiFi connection is a breeze. Just open the app and it automatically detects your new Uni Box S3 and walks you through the setup process. Comfortably reset the WiFi connection via long press of the Stream button on the front panel.
The Uni Box S3 even allows you to stream any of your connected devices - turntable, CD player or even TV - to other compatible streamers*.
*Compatible with Uni Box S3. Compatible with Stream Box E, Stream Box S3 & Wireless Box E available later in 2025.
