Tells you which of the two contacts of your mains connection is the phase

Checks your earth connection

Detects if your mains is normal type or balanced type

For a good audio performance it is very important that the equipment is connected to the mains the right way. But which way is right? Manufacturers often indicate phase on their equipment or plug, the only thing to find out yet is where the phase is on the mains socket.

Also important for your equipment is a correct earth connection. Not having earth is an unsafe condition. A bad earth condition or no earth at all can cause problems in sound reproduction. Hum is a very audible result, but sometimes we just realise what details we miss until we hear this piece of music somewhere else.

The Sound Saver has a clever circuit which measures both mains contacts and earth. With two LEDs (light emitting diodes) it indicates which mains contact is phase. Only one LED will light. The other mains contact is neutral; it is at about the same level as earth. Watch out, it should be in theory! In practise, due to some effects in leads or equipment, the neutral and earth can differ up to some volts. The result of this difference in voltage can be very serious for your sound.

If the Sound Saver gives no indication at all, then the mains earth contact is not
connected. Watch out! No LEDs does NOT mean no voltage! Don't touch the bare
contacts of the mains, this can be very dangerous. When both LEDs light up, you have a balanced mains condition. Here the difference between phase and neutral can not be determined, in fact the contacts are both phase. This condition is problematic, but can give -under strict terms- some advantages for equipment with problematic power supplies.

The Sound Saver is your easy tool to answer questions about connecting your
equipment to the mains the right way.
