The Phono Box S3 B is a high-quality phono preamplifier designed to enhance your vinyl listening experience. Its balanced and discrete circuitry ensures superior sound quality making it an essential component for audiophiles seeking to elevate their analog audio systems.FeaturesBalanced Connections for True High-Fidelity SoundDiscrete Circuitry for Enhanced Audio DetailSemi-Passive RIAA EqualizationWide Cartridge CompatibilityRobust Elegant Build QualityEnhanced Design and Build QualityHoused in a new larger steel and aluminum chassis the Phono Box S3 B offers increased rigidity and effective isolation from external interference. Available in silver and black finishes it seamlessly integrates into any hi-fi setup.Balanced Connections for Superior SoundThe 'B' in Phono Box S3 B stands for 'Balanced.' It supports balanced connections allowing you to upgrade to true balanced operation with a moving coil (MC) cartridge on most Pro-Ject turntables. Balanced transmissions utilize both hot and cold (positive and negative) signals effectively carrying identical musical information. A true balanced gain stage extracts the final musical details from these signals while minimizing hum and noise a technique commonly used in professional recording studios.Discrete Circuitry for High-Fidelity AudioThe gain stage of the Phono Box S3 B features a fully discrete layout meaning it is composed of individual electronic components rather than integrated circuits. This design choice though more costly and time-consuming results in superior sound quality providing a more authentic and detailed audio reproduction.Semi-Passive RIAA EqualizationAfter processing the balanced signals independently they are combined and sent through a semi-passive RIAA equalization stage. Maintaining a fully symmetrical gain stage optimizes the signal-to-noise ratio and minimizes interference ensuring the equalization section receives an optimal signal for precise audio reproduction.Versatile Compatibility and

The Pro-Ject Phono Box DC is a dedicated phono preamplifier designed to enhance your vinyl listening experience. By amplifying the delicate signals from your turntable's cartridge it ensures clear low-noise sound reproduction allowing you to fully appreciate the depth and imaging of your records.FeaturesMM and MC Cartridge CompatibilityHigh-Quality Sound ReproductionCompact and Stylish DesignVersatile CompatibilityEquipped with both Moving Magnet (MM) and Moving Coil (MC) cartridge support the Phono Box DC offers flexibility for various turntable setups.
