Every turntable needs proper grounding, otherwise electrical hum may be induced. If a turntable is not properly grounded, it may have a different reference potential than the connected amplifier. Consequently, these potential differences induce a compensating current which can be heard as hum.Read More
Therefore all good turntables have a separate ground cable which can be connected to standard amplifiers or phonostages, which usually have a ground terminal. This way different potentials are equalized and hum is no longer audible. However, many modern amps, especially most amps of soundbars or streaming speakers have no ground connection. These systems are referenced as “ floating mass systems“. If a standard turntable is connected to such a „floating mass“ amplifier, audible hum will be the result.
Therefore we designed the High Power it power supply. The High Power it is a three pin power supply with ground connection for Pro-Ject turntables to get rid of these ground related hum problems, especially occurring with amplifiers with „floating mass“, which have no real ground connection.
Proper grounding dramatically reduces grounding hum of „floating mass“ systems/amplifiers
3 pin DC power supply with ground connection
Delivers cleaner current and more power to all Pro-Ject turntables
