Pro-Ject Audio Systems Phono Box DS3 B - Black

'One of the most cost effecting Balanced phono stages you can buy'

In addition to settings for MM (Moving Magnet) cartridges, the Phono Box DS3 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. 

After treating the balanced signals they are added back together and processed by the fully passive and discrete RIAA equalization stage. By keeping the gain stage fully symmetrical we can optimize the signal to noise ratio, giving the EQ section the best source to work its magic on.

Additionally, this box uses fully discrete audio circuitry composed of electronic components which are disparate, individual devices (also called discrete components). Countless hours of listening tests and years of experience have shown us that even the very best Op-Amps do not tend to be as neutral, natural, dynamic nor vivid as we’d prefer.
