Naturally balanced
Turntable cartridges naturally provide a balanced signal. To fully utilize the balanced signal, we recommend nadbuilding your turntable with an MC head.
Combined with the new True Balanced cables, you will achieve sound quality that was previously only available in more expensive devices.
Every turntable Pro-Ject with RCA, miniXLR or 5-pin connector is compatible with this technology.
