The SoundSend App has many great functions to manage your Sound Stage.
In the Advanced Settings tab, you can change your Speaker Configuration, adjust your speaker distances in MyZone, initiate Scan for Speakers, Factory Reset the SoundSend, check your Audio Formats and get Device Version information.
To change your speaker position you need to use the Channel Check button. When you click the Channel Check button, you will see a map based on your selected speaker configuration. All speakers that are discovered will show up on this map. You can click on each speaker to make it Chime, or you can click, hold and move the location of the speaker. Once this is set, SoundSend will save your configuration a and your setup will remain the same until the SoundSend is factory reset.
