Project High Power it Power Supply Upgrade
The High Power IT is a three-pin power supply with a ground connection for Pro-Ject turntables. It gets rid of ground-related hum problems, especially occurring with amplifiers that have no real ground connection.
If a turntable is not properly grounded, it may have a different ground reference to the connected amplifier. Consequently, these potential differences induce a compensating current which can be heard as a hum. Many modern amps, especially those used in soundbars and streaming speakers (but also found across a wide variety of hi-fi separates), have no ground connection, and can therefore experience this problem. These systems are called, in technical terms, "floating mass systems". If a standard turntable is connected to such a "floating mass" amplifier, then an audible hum can be the result.
High Power IT solves this issue by adding a grounded connection directly to the turntable's power supply, delivering a cleaner current and more power to Pro-Ject 15V DC turntables
