The center line represents the normal air pressure, and when there is a positive change in air pressure, the line goes up, and vice versa when there is a negative change in air pressure.

When you see a sound wave graph, you will see a sound wave as a series of positive and negative changes in pressure. However, when you swap the connections, you can reverse the polarity of the speakers. When you connect the positive speaker terminal to the positive amplifier terminal and the negative speaker terminal to the negative amplifier terminal, the speakers have the correct polarity. You can determine speaker polarity while connecting wires between speakers and amplifiers. On the other hand, the negative terminal connects to the negative signal wire carrying a negative polarity signal wire. Here, you connect the positive terminal to the positive signal wire, which carries the mono signal of positive polarity. The two terminals of the speaker, positive and negative, accept the same mono signals in opposite polarity. It means out of the two conductor wires, one wire carries signals while the other acts as a ground. When the speakers carry high signal levels, the signals run unbalanced.

Choose a DC Source model for use in a vehicle or other 12VDC - 28VDC portable power source. Choose an AC Source model for use with either US/Canada (120VAC) or International (100-240VAC 50/60Hz) wall current.

You may have to file a small slot in the cover for a perfect fit (using included file). Our 9 Volt Battery Eliminators get power through a thin flat cable that is run under your battery compartment cover. They are compatible with both 9 volt battery snap connectors as well as press fit terminals. Our 9 Volt Battery Eliminators fit into the standard 9 volt battery compartment in your device. Weight: Approximately 20 grams including the wire, 10 grams without wire. Note: If you want to be able to attach a higher DC voltage (like a 12VDC battery) and get a 9VDC output then you need our BE-9-DC product as it has a built-in voltage regulator. This unit has NO electronics, so whatever voltage you attach to it is the output voltage at the terminals. Make your own battery eliminator using our custom 9 Volt battery cell with contacts and cable pre-assembled. Our custom 9 Volt wired/active cell ('fake battery') with contacts and 3 foot cable. Does not change or regulate the voltage.
