The only reason you would want to use Channel A (RF+LF+RR+LR) is if you wanted to be able to customize the volume for each speaker. Which may not be good if you have multiple people listening from different location. If you want to be able to hear same volume, without having to customize it then you would do Channel A (R+L) and Channel B (R+L). Hope this helps.
