A:AnswerThe manual states "Speaker A/B switching: Lets you easily switch between 2 sets of speakers". There was nothing that said you could play speakers A & B at the same time. It says you can switch between 2 sets of speakers. Some receivers have either A or B selection, others have A, B or A & B at the same time.

Short answer is No. Looks like you can only choose A or B speakers. If you wanted to run speakers A & B at the same time you could connect them to one speaker out and they'd play at the same volume.
