By taking measurements in and around the prime listening position

Designed for mid- to high-end multichannel systems

The dual layer voice coil design maximizes linearity and accuracy at full excursion while minimizing distortion and power compression

through the use of high quality relays

Pro-Ject Phono Box DS3 B Serie PA By taking measurements in andPhono 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 operations on the signal path, and optimized by performing many hours of listening and tuning. The circuit topology foresees, 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 preamplifiers.
