PRO-JECT PHONO BOX DS3 B

Phono Box DS3 B, where “B” stands for balanced.

Pro-Ject Phono Box DS3 B uses a completely discrete design, therefore without the adoption of any operation on the signal path, and optimized by performing many hours of listening and tuning. The circuit topology provides, after a first input stage, a completely passive RIAA equalization, with consequent further improvement of the signal / noise ratio, which is the main problem of all Phono preamps. Finally the output stages, separated for RCA or XLR and low noise.
