The Pro-Ject High Power it 2 is a linear power supply designed for Pro-Ject turntables running on a 15V DC supply. Going beyond a standard wall adaptor, it delivers a cleaner, more stable DC output to reduce electrical noise and motor interference that can degrade sound quality.
Unlike conventional switch-mode adaptors, the High Power it 2 uses a three-pin DC connector with a ground connection. This dedicated grounding path solves a common problem with modern floating-mass amplifier systems, including soundbars, streaming speakers, and many contemporary integrated amplifiers, which have no ground terminal of their own. Without a proper ground reference, a turntable connected to such systems can produce an audible low-frequency hum; the High Power it 2 eliminates this by providing a stable earth path directly through the power supply.
Compatible with all Pro-Ject turntables requiring a 15V DC supply, the High Power it 2 is a practical upgrade that addresses both power quality and grounding in a single unit. It is particularly recommended for users pairing a Pro-Ject deck with a modern streaming system or soundbar.
