Description
Pro-Ject Phono Box DS3 B Phono Preamplifier
The Pro-Ject Phono Box DS3 B Phono Preamplifier incorporates a true, fully balanced gain stage design. Whether you’re using a single-ended RCA or balanced connection, both times the fully symmetrical gain stage can optimize the signal-to-noise ratios, feeding the fully passive and discrete RIAA equalization stage with the cleanest signal to work its magic on.

True Balanced
Phono Box DS3 B is ready for our new True Balanced Connection. Single-ended RCA connections, quite literally, only use half of your cartridge’s output. With one of our new True Balanced phono cables and an MC cartridge you’ll hear details and dynamics, previously exclusive to only the most expensive phono stages. A truly balanced gain stage can extract the final musical information, effectively filtering out any noise from interferences.
