Rather than being just another app-led streaming box, it combines Pro-Ject’s analogue amplifier know-how with modern network audio features in one neat component.\u003c\/p\u003e\n\n\u003cp\u003eA big part of the appeal is the way it bridges traditional hi-fi and modern streaming. The Uni Box S3 keeps analogue sources such as turntables in the analogue domain, while also adding WiiM-powered streaming, Bluetooth, Wi-Fi and digital inputs for TVs and other source devices. That makes it a strong option for customers who want one compact unit that can handle vinyl, streaming and TV sound without feeling like a compromise.\u003c\/p\u003e\n\n\u003cp\u003eIt is also designed to be practical in everyday use. With a built-in MM phono stage, headphone output, remote control and the ability to stream connected sources to other compatible Pro-Ject streamers, the Uni Box S3 offers a lot of flexibility for its size. For customers wanting a compact amplifier with modern streaming convenience and real hi-fi credibility, the Uni Box S3 is an excellent choice.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAll-in-one design combines integrated amplification and modern streaming in one compact unit\u003c\/li\u003e\n\u003cli\u003eFully analogue pre and power amp design helps preserve the character of analogue sources such as turntables\u003c\/li\u003e\n\u003cli\u003eBuilt-in MM phono stage makes it easy to connect a turntable without needing an extra box\u003c\/li\u003e\n\u003cli\u003eWiiM-powered streaming opens up access to major music services and multi-room options\u003c\/li\u003e\n\u003cli\u003eBluetooth, Wi-Fi, coaxial, optical and eARC inputs make it easy to connect TVs, streamers and other digital sources\u003c\/li\u003e\n\u003cli\u003eCan stream connected devices such as turntables, CD players and TVs to other compatible Pro-Ject streamers\u003c\/li\u003e\n\u003cli\u003eHeadphone output adds simple private listening without needing a separate headphone amplifier\u003c\/li\u003e\n\u003cli\u003eCompact aluminium casework keeps the system neat while still feeling like a proper hi-fi component\u003c\/li\u003e\n\u003cli\u003e2 years manufacturers warranty, extended to 3 years if registered with Pro-Ject within 4 months of purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv id=\"hb-uniboxs3-panel-2\" class=\"hb-panel\"\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eAmplifier \u0026amp; Streaming Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Integrated streaming amplifier\u003c\/li\u003e\n\u003cli\u003ePower Output: 2 x 23 W into 8 ohms \/ 2 x 40 W into 4 ohms (1% THD)\u003c\/li\u003e\n\u003cli\u003eAmplifier Design: Fully analogue pre and power amplifier, dual mono design principle\u003c\/li\u003e\n\u003cli\u003eHeadphone Output: 70 mW at 32 ohms (1% THD)\u003c\/li\u003e\n\u003cli\u003eAnalogue Inputs: 2 x pair RCA, 1 x phono MM (RCA)\u003c\/li\u003e\n\u003cli\u003eDigital Inputs: RCA coaxial, 2 x Toslink, eARC, Wi-Fi \/ Bluetooth streaming input\u003c\/li\u003e\n\u003cli\u003eDAC: Cirrus Logic CS4344, 24-bit \/ 192 kHz\u003c\/li\u003e\n\u003cli\u003ePower Amplifier Stage: Texas Instruments TPA3221DDV\u003c\/li\u003e\n\u003cli\u003eVariable Output: 1 x pair RCA\u003c\/li\u003e\n\u003cli\u003eSpeaker Connections: 4 mm banana plugs, spades or bare wire\u003c\/li\u003e\n\u003cli\u003eWireless Connectivity: Wi-Fi 5, 802.11 b\/g\/n\/ac dual band 2.4 GHz and 5 GHz, Bluetooth 5.0, SBC, AAC\u003c\/li\u003e\n\u003cli\u003eStreaming Platform: WiiM OS\u003c\/li\u003e\n\u003cli\u003eStreaming Services: Spotify, TIDAL, Amazon Music, Qobuz, Napster, Pandora, TuneIn, Deezer and more\u003c\/li\u003e\n\u003cli\u003eExtra Features: Multi-room streaming, EQ functions, remote control, analogue volume control with motorised potentiometer\u003c\/li\u003e\n\u003cli\u003ePower Supply: 20 V \/ 3 A DC, 100 - 240 V, 50 \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003eStandby Power Consumption: Less than 0.5 W\u003c\/li\u003e\n\u003cli\u003eColour Options: Black or silver\u003c\/li\u003e\n\u003cli\u003eMade In: Europe\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWeight \u0026amp; Dimensions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 20.6 x 5.5 x 15.3 cm (W x H x D)\u003c\/li\u003e\n\u003cli\u003eWeight: 1.1 kg without power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePro-Ject Uni Box S3 integrated streaming amplifier\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003ePower supply\u003c\/li\u003e\n\u003cli\u003eProduct documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Pro-Ject","offers":[{"title":"Silver","offer_id":57914533118339,"sku":null,"price":699.0,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":57914533085571,"sku":null,"price":699.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0160\/4606\/3670\/files\/Untitled_3500x3500px_-2026-04-28T134100.878.png?v=1777380174","url":"https:\/\/www.holburnonline.co.uk\/products\/pro-ject-uni-box-s3-integrated-amplifier","provider":"Holburn Online","version":"1.0","type":"link"}
