ProJect Phono Box S3 B

Lift up your analog audio with the ProJect Phono Box S3 B! Enjoy clarity and sound detail that was meant to be heard. This phono preamplifier has you covered to help you experience every nuance of your favourite vinyl records. Why buy? Because you deserve to let the music move you!

High End Features Made Accessible

The Phono Box S3 B comes in completely redesigned casework. The larger size (than the S2) enables a completely new feature set that breaks new ground at the price. The steel & aluminium case offers very high rigidity and isolation against outside interferences, which is essential for the new technology inside.

Fully Discrete and Symmetrical Gain Stage

The new Phono Box S3 B gain stage uses a fully discrete layout. A discrete circuit is composed of disparate electronic components and individual devices that result in better sound quality. 

The amplifier section of the Phono Box S3 B is built of single parts and doesn‘t use any integrated circuits. This makes for a longer and more costly design process but the resulting audio speaks for itself.

True Balanced Connection

 Part of the Phono Box S3 B's redesign is the inclusion of a balanced signal at a terrific price point. And the best part is that thanks to a range of new cables from ProJect, these inputs can be used with any ProJect turntable, whether it has RCA or 5P XLR outputs. 

However, to truly utilise the balanced circuitry, a ProJect turntable with a moving coil cartridge and 5P output can be connected to the Phono Box S3 B with a 5P to XLR cable. The decreased noise and interference and improved dynamics have to be heard to be believed.
