To use SpeakerAngle, simply select the desired mode of operation (Stereo or Surround), then place your iPhone, iPad or iPod Touch on top of the speaker you want to angle. Set the speaker so that it is facing straight ahead, then touch the corresponding speaker icon so that it lights up. Next, touch the icon's number box to let SpeakerAngle know that the selected speaker is currently at zero degrees.
Now physically rotate the speaker inwards (that is, towards the listening position). The selected speaker icon will move accordingly, and the number box below it will display the degree to which the speaker is angled. When the speaker is angled within the industry recommendation of 20˚ to 45˚, the number box changes color, from red to green. When you touch the speaker icon once again (or select any other speaker), the number box changes color to orange, and "freezes" the currently displayed angle.
Finally, touch the paired speaker icon (for example, the right speaker in a stereo system if you have just angled the left speaker). Pick up your iPhone, iPad or iPod Touch and place it on top of that speaker, then touch the number box below the speaker icon. Physically rotate the speaker inwards until the number box changes color to yellow, indicating that this speaker is now angled to the same degree as the first one.
To continue experimenting with different speaker angles, you can start from scratch at any time by pressing SpeakerAngle's RESET button. That's how easy it is to get great-sounding audio from your speaker system!
