Pro-ject - Phono Box S3 B

Balanced & Discrete MM/MC Phono Preamp

The New Balanced S3 Phonostage

The Phono Box S3 B comes in a new, larger enclosure. Due to the bigger case, we were able to bring new features to our S3 phono preamplifier. The new steel & aluminum chassis with aluminum buttons brings very high rigidity and effective isolation from interference. The Phono Box S3 B is available in silver and black and is ready for use in any hifi setup.

‘B’ for Balanced

In addition to settings for MM (Moving Magnet) cartridges, the Phono Box S3 B allows you to upgrade to True Balanced operation with a MC (moving coil) cartridge on most Pro-Ject turntables. Balanced transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A True Balanced gain stage can now extract the final musical information out of the +/- signals and subtract the hum and noise picked up during the transmission. This is the same concept used with every microphone in every professional recording studio worldwide.

  • 5-pin mini XLR balanced input
