Pro-Ject PJ97822444 HIGH POWER IT Grounded 15V Power Supply

The Pro-Ject PJ97822444 HIGH POWER IT. 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.

Therefore all good turntables have a seperate 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 Pro-Ject PJ97822444 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. Moreover, the High Power it delivers cleaner current and more power to all 15V DC Pro-Ject turntables.

Long-Term Support

All Pro-Ject Audio Systems products are produced under the highest possible level of quality control. Every single product runs through a four-hour testing procedure wherein the mechanical and electrical performances, as well as the sound characteristics, are checked. Only when the product satisfies our expert test team may it leave our factory.

The Beginning

Pro-Ject was founded in 1991, during the onslaught of the compact disc and CD players. With the mission to offer the best analogue experience for reasonable prices especially with the Pro-Ject PJ97822444 HIGH POWER IT. In a time where the digital audio media had been on the rise, and vinyl was declared as outdated and dead, Heinz Lichtenegger kept his belief in the simple but best way to enjoy music – turntables.
