Improve your turntable power supply for the best performance possible. The High Power it also includes a UK Mains Plug. 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.What You Get1 x High Power ITSpecifications Turntable Output Power: 15V DC / 1A Dimensions (W x H x D): 97 x 42 x 30 mm Weight: 0.1 kg Warranty: 2 Years
