Product details

The "Phono Box S3 B" redefines the category of affordable phono preamplifiers by combining audiophile sound quality with balanced technology. This innovative device raises the bar for vinyl playback quality by creating a seamless and highly customisable connection between your turntable and your amplification system.

A crucial factor in the sound quality of a phono preamplifier is its ability to adapt precisely to the specific characteristics of a cartridge. The Phono Box S3 B masters this challenge with flying colours by offering extensive adjustment options for the termination capacity and the amplification factor. This flexibility ensures that every cartridge - whether moving magnet (MM) or moving coil (MC) - can operate in its ideal electrical environment, enabling optimised signal transmission and therefore outstanding sound quality. The gain can be adjusted in four precisely tuned stages to ensure perfect adaptation to the output signal of your pickup. This adaptability ensures that the Phono Box S3 B is suitable for a wide range of MM and MC cartridges, making it an extremely versatile tool in your hi-fi setup.

An outstanding feature of the Phono Box S3 B is its balanced inputs and outputs, which significantly improve signal integrity and reduce noise. This is particularly beneficial in environments with high electromagnetic interference potential, as it preserves the purity of the audio signal and enables dynamic, clear and unadulterated music enjoyment.

The Phono Box S3 B goes one step further with the integration of two inputs and enables the simultaneous connection of two turntables or one turntable with two tonearms. This function is particularly useful for vinyl lovers who want to use different pickup systems for different types of records. When switching between the inputs, the device automatically loads the individually stored settings for the respective cartridge, which greatly simplifies operation and ensures optimum sound quality for each record.

Pro-Ject's symmetry project has been given a powerful boost with the Pick it Pro Balanced, X1 B, Connect it Mini XLR and Phono Box S3 B chain. For a really attractive overall price, you get a sensible technology that won't overwhelm any customer. To be asymmetrical for a moment: There is almost nothing on the negative side. On the positive side, there's a whole lot. Chapeau!
