The Test Files. Three files here: a monoral low frequency rumble, a 75 Hz sine tone and a guitar recording, all with their respective "in phase" and "out of phase" variations. From a central listening position, listen to the "in phase" and "out of phase" versions. If your speakers are correctly set up, the "in phase" versions will:

The opamp 741 is the core of the polarity indicator circuit. Its non-inverting input is used to test the points for polarity. It has a gain of around 150 which enables it to test low voltage levels. The test result is displayed through the two LED’s D1 and D2. D1 lights up by positive polarity and D2 lights up by negative polarity. Take note that the pin profile on the diagram is …

To use the circuit, just connect your probes to the source under test. If D1 lights up, the left most probe (on the schematic) is connected to positive. The opposite is true if the left probe is negative. If both LEDs are on, the source being probed is AC. Be careful when using this tester not to probe a source greater than about 12V.
