All-in-One Stereo Control Centre
The Pro-Ject Pre Box S3 is a highly versatile stereo preamplifier designed to unite analogue, digital, and wireless sources in a single compact component. Built into an aluminium S3 chassis, it offers excellent shielding, superior durability, and clean signal paths throughout, making it a natural hub for any modern hi-fi system.
Advanced Analogue Performance
At its heart, the Pre Box S3 features a dedicated moving-magnet phono stage engineered for low noise, high gain, and exceptional linearity, allowing vinyl records to retain their natural tonality and dynamic presence. A motor-driven analogue volume control provides precise adjustment while preserving signal purity, and dual-mono circuitry enhances stereo imaging and channel separation for an authentic high-fidelity experience.
High-Resolution Digital Technology
Digital sources are handled with finesse thanks to a Cirrus Logic CS4344 24-bit/192kHz DAC, delivering clean, detailed, and articulate sound across all supported inputs. Bluetooth 5.0 with aptX HD enables high-quality wireless streaming up to 24-bit/48kHz, making it straightforward to enjoy near-lossless audio from smartphones, tablets, or computers. A built-in headphone amplifier with a 6.3mm output (16-600 ohms) adds further versatility for personal listening.
Comprehensive Connectivity
The Pre Box S3 provides 13 versatile inputs and outputs to accommodate turntables, televisions, streaming sources, and more. Its eARC input allows seamless connection to modern televisions, while coaxial and optical S/PDIF inputs support digital audio at up to 24-bit/192kHz. Flexible output options include variable RCA to feed power amplifiers or active speakers, a fixed line-level output for secondary zones or headphones, and a dedicated subwoofer output. RS232 and 12V trigger connections allow integration into custom installation and smart home environments.
Elegant, Space-Saving Design
Finished in silver, the Pre Box S3 blends effortlessly into any modern hi-fi setup. Designed and manufactured in Europe, it reflects meticulous attention to detail and a commitment to quality craftsmanship. Also available in black.
