Its analogue preamplifier and power amplifier path keeps connected analogue sources in the analogue domain, while a separate Cirrus Logic DAC handles digital playback. That distinction is useful for someone with an existing turntable or CD player who also wants modern streaming without adding several components.\u003c\/p\u003e\n\u003ch3\u003eWiiM-Powered Streaming\u003c\/h3\u003e\n\u003ch4\u003eModern music access with familiar component controls\u003c\/h4\u003e\n\u003cp\u003eWiiM OS provides the network streaming platform, while the Pro-Ject Home app handles streaming setup and control. The digital section uses a Cirrus Logic CS4344 converter supporting up to 24-bit\/192kHz audio. Spotify Connect, TIDAL Connect and Qobuz connectivity bring popular music services into the same system as your physical sources.\u003c\/p\u003e\n\u003cp\u003eConnect the Uni Box S3 to a suitable home Wi-Fi network and use the app for streaming functions. Traditional source selection and volume remain available directly on the front panel, so ordinary amplifier use does not depend on keeping a phone nearby.\u003c\/p\u003e\n\u003ch3\u003eAnalogue Amplification and Speaker Matching\u003c\/h3\u003e\n\u003ch4\u003eCompact power for an appropriately matched pair of passive speakers\u003c\/h4\u003e\n\u003cp\u003eThe Uni Box S3 is rated at 2 x 23W into 8 ohms or 2 x 40W into 4 ohms, measured at 1% THD. That is substantial capability for its compact dimensions, although room size, listening distance and speaker sensitivity remain important when choosing a matching pair.\u003c\/p\u003e\n\u003cp\u003eIt is well suited to a modest living-room or study system with efficient standmount speakers. For a large room, long listening distance or consistently high playback levels, we would check speaker requirements carefully before recommending this amplifier.\u003c\/p\u003e\n\u003ch3\u003eTurntable and Analogue Sources\u003c\/h3\u003e\n\u003ch4\u003eA dedicated MM phono input and two additional RCA inputs\u003c\/h4\u003e\n\u003cp\u003eThe built-in moving-magnet phono stage allows a compatible turntable to connect directly, without requiring a separate phono preamplifier. Two further stereo RCA inputs accommodate components such as a CD player, external DAC or another line-level source.\u003c\/p\u003e\n\u003cp\u003eTurntables with their own built-in phono stage should normally feed a line input, rather than sending a preamplified signal into the Uni Box S3's phono input. Check the cartridge type and phono-stage arrangement before making the connection.\u003c\/p\u003e\n\u003ch3\u003eTV and Digital Audio Integration\u003c\/h3\u003e\n\u003ch4\u003eBring television and digital sources into a stereo system\u003c\/h4\u003e\n\u003cp\u003eHDMI ARC provides a convenient path for compatible TV audio, alongside two Toslink optical inputs and one coaxial S\/PDIF input for other digital components. The compact unit can therefore serve as the amplifier for both everyday music listening and TV sound through a pair of passive hi-fi speakers.\u003c\/p\u003e\n\u003cp\u003eCheck the television's ARC output settings and supported audio format during setup. This is a stereo amplifier rather than a surround-sound AV receiver, so it should be selected for two-channel use.\u003c\/p\u003e\n\u003ch3\u003eHeadphone Listening and System Expansion\u003c\/h3\u003e\n\u003ch4\u003ePrivate listening and a variable line-level output\u003c\/h4\u003e\n\u003cp\u003eA front headphone socket is backed by a dedicated output rated at 70mW into 32 ohms. A variable stereo RCA output also provides a connection to compatible downstream equipment, allowing flexibility when planning an expanded system.\u003c\/p\u003e\n\u003ch3\u003ePlacement and Daily Use\u003c\/h3\u003e\n\u003ch4\u003eSmall enough for a shelf, with sensible ventilation still required\u003c\/h4\u003e\n\u003cp\u003eThe aluminium enclosure is 206mm wide and 55mm high, with a chassis depth of 153mm or 176mm including sockets. Leave room for cable bends, access to the rear terminals and airflow around the case. For wireless streaming, consider router distance and local network reliability when choosing the final shelf position.\u003c\/p\u003e\n\u003ch3\u003eAvailable Variants\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack:\u003c\/strong\u003e black aluminium finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilver:\u003c\/strong\u003e silver aluminium finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated two-channel amplifier with WiiM-powered streaming\u003c\/li\u003e\n\u003cli\u003e2 x 23W into 8 ohms or 2 x 40W into 4 ohms at 1% THD\u003c\/li\u003e\n\u003cli\u003eDedicated moving-magnet phono input and two stereo RCA line inputs\u003c\/li\u003e\n\u003cli\u003eHDMI ARC, two optical and one coaxial digital input\u003c\/li\u003e\n\u003cli\u003eCirrus Logic CS4344 DAC supporting up to 24-bit\/192kHz\u003c\/li\u003e\n\u003cli\u003eWi-Fi and Bluetooth wireless connectivity\u003c\/li\u003e\n\u003cli\u003eHeadphone output and variable stereo RCA output\u003c\/li\u003e\n\u003cli\u003eCompact aluminium chassis in Black or Silver\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eIntegrated stereo streaming amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower output\u003c\/td\u003e\n\u003ctd\u003e2 x 23W \/ 2 x 40W into 8 \/ 4 ohms (1% THD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower amplifier\u003c\/td\u003e\n\u003ctd\u003eTexas Instruments TPA3221DDV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDAC\u003c\/td\u003e\n\u003ctd\u003eCirrus Logic CS4344, up to 24-bit\/192kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalogue inputs\u003c\/td\u003e\n\u003ctd\u003e2 x stereo RCA line;

Its proper MM phono input and analogue signal path are useful distinctions from many streaming-first amplifiers.\u003c\/p\u003e\n\u003cp\u003eThe main decision is speaker matching. With 23W per channel into 8 ohms, we would pair it thoughtfully with speakers and a listening distance that suit its output, rather than judge it by the amplifier's small size. For a study, apartment or carefully planned living-room stereo, it brings together a well-rounded connection set and accessible everyday control.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pro-Ject","offers":[{"title":"Black","offer_id":68068358914235,"sku":null,"price":1599.0,"currency_code":"AUD","in_stock":true},{"title":"Silver","offer_id":68068358947003,"sku":null,"price":1599.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0252\/1956\/3610\/files\/project-uni-box-s3-black.png?v=1793490179","url":"https:\/\/theaudioexperts.com.au\/products\/pro-ject-uni-box-s3-integrated-streaming-amplifier","provider":"The Audio Experts","version":"1.0","type":"link"}
