It takes some of the standout features of the RS range—especially the new True Balanced Connection—and packages them into a compact, well-engineered chassis suited for real listening rooms.\u003c\/p\u003e\n\n\u003ch3\u003eHigh-End Features and Limitless Loading Options\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the DS3-B is a true fully balanced gain stage design. Whether you connect a turntable through single-ended RCA or balanced XLR, the symmetrical gain stage can optimize signal-to-noise ratio before the signal reaches the equalisation stage. The chassis combines steel rigidity with aluminum panels for better isolation from interference, vibration, and the electrical noise common in modern households.\u003c\/p\u003e\n\n\u003ch3\u003eDual Turntable Inputs with Memory\u003c\/h3\u003e\n\u003cp\u003eYou can connect up to two turntables at the same time, and each input stores its own settings in memory. That makes switching between decks fast and accurate, whether you are moving from a main listening turntable to a secondary vintage or DJ-oriented table. It is one of the most practical reasons to choose the DS3-B over a basic single-input phono stage.\u003c\/p\u003e\n\n\u003ch3\u003eContinuously Variable Impedance Control\u003c\/h3\u003e\n\u003cp\u003eLoad impedance can be set continuously via a potentiometer—a system invented by Pro-Ject Audio Systems—so you can adjust loading during playback and assess the sonic result in real time. This makes cartridge matching more intuitive than ordinary stepped-impedance switches and helps you find the setting that sounds best with your specific turntable, cartridge, and cable combination.\u003c\/p\u003e\n\n\u003ch3\u003eTrue Balanced Connection\u003c\/h3\u003e\n\u003cp\u003eCartridges are balanced signal transducers by nature. The DS3-B takes advantage of that through its True Balanced Connection design. While MM cartridges are commonly wired for single-ended output, MC cartridges can access a more complete balanced signal path. Together with Pro-Ject’s True Balanced Connection cables, the DS3-B unlocks cleaner signal extraction, lower noise, and better rejection of interference from household appliances, Wi-Fi, power cables, and audio amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eFully Discrete Audio Circuitry\u003c\/h3\u003e\n\u003cp\u003eThe DS3-B uses fully discrete audio circuitry rather than relying entirely on op-amps. Discrete circuits are built from individual electronic components, and Pro-Ject’s engineering suggests this approach tends to sound more neutral, dynamic, and musically engaging. The passive RIAA equalisation is entirely split, which supports better impedance matching and closer adherence to the ideal RIAA curve.\u003c\/p\u003e\n\n\u003ch3\u003eExpandable Design\u003c\/h3\u003e\n\u003cp\u003eMagnetic wooden side panels are available separately, so you can customize the look of the unit to match your system or room. This reflects the broader product philosophy: high performance, flexible setup, and user-friendly design.\u003c\/p\u003e\n\n\u003ch3\u003eBest For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-turntable audiophile systems\u003c\/li\u003e\n  \u003cli\u003eUpgrading from entry-level or non-balanced phono stages\u003c\/li\u003e\n  \u003cli\u003eMC cartridge owners interested in balanced playback\u003c\/li\u003e\n  \u003cli\u003eListeners who want real-time impedance adjustment without complicated tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eIf you want balanced phono performance, dual inputs, and Pro-Ject’s cartridge-matching flexibility in one compact box, the Phono Box DS3-B is one of the most practical next steps from stereo playback to serious vinyl listening.\u003c\/p\u003e","brand":"Pro-Ject","offers":[{"title":"Black","offer_id":43315779043405,"sku":"PJ97829351","price":999.0,"currency_code":"CAD","in_stock":true},{"title":"Silver","offer_id":43315779076173,"sku":"PJ97829375","price":999.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/0681\/2493\/files\/PJ97829351_1.jpg?v=1785094670","url":"https:\/\/acoustipower.com\/zh-hant\/products\/pro-ject-phono-box-ds3-b","provider":"Acoustipower","version":"1.0","type":"link"}
