The PhaseCheck app will run a test signal through your sound system to ensure your speakers are in-phase and wired with the correct polarity. It can be run either manually or automatically. Manual mode allows you to run the test signal and flip the phase so you can listen yourself to ensure your sound system is setup correctly. Automatic mode will run a series of test signals through your sound system and use the microphone on the device to analyse the results.You should check the phase of your sound system whenever the wiring has been changed to ensure everything is the correct polarity.When a sound systems speakers are out of phase the sound quality is affected massively. Bass is reduced significantly and stereo imaging gives the illusion of the sounds pulling outside of the room.To run the check connect your iOS device to your sound system so it can play audio. If possible place the iOS device evenly between the speakers. Phase cancellation will not occur close to the speakers so ensure the device is not too close. Ensure the volume is at a comfortable listening level and if possible ensure there is no background noise to interfere with the scan.
