Three noise tracks are included in the Subwoofer Test Pattern Premium suite:
Each file lasts 1 minute and was recorded at 0 dBFS.
These files are useful for leveling, stereo balance and speaker placement tests. As you play each noise file, check that both speakers have the same volume. Make panning adjustments if necessary. These tests are particularly helpful when placing multiple speakers or when each speaker has individual volume and EQ controls.
Next, walk around your room while playing the noise signals to identify changes in the volume coming from different speakers.
Adjust the panning and volume of the speakers using their respective controls, and reposition the speakers if necessary.
