High-quality phase tester for determining the correct power phase when connecting your audio devices from Essential Audio Tools. To achieve the best possible performance from your audio equipment, it is essential to phase the devices correctly. This refers to the proper orientation of the power plug in the socket, as each plug can be inserted into the socket in two different ways. Correct and incorrect phases often have significant sonic impacts. Proper phasing helps to avoid common-mode and differential-mode interference.

Some audio devices have a phase marking for the "hot" conductor. The Sound Saver allows you to determine the phase of the power outlet thanks to its clever circuitry. The illuminated LED indicates where the phase is located. If the Sound Saver shows no indication, the grounding is not properly connected. If both LEDs light up, a so-called symmetrical connection is present. With the two LEDs, identification is incredibly simple. Unlike other systems, the Sound Saver immediately shows you the correct phase polarity. Confusion is eliminated.
