re: HR-722

Can anyone tell me how to connect a subwoofer to the HR-722? I'd like to augment my 2 fronts with a sub, but don't know if I can simply connect the sub to the B speaker outputs and play both A and B together.

re: HR-722

Get a sub with speaker level connections. Connect the L R speaker wires to the "speaker in" connections on the sub first, then connect the speakers to the "speaker out" connections on the sub. The sub will have a crossover that feeds bass to sub, but not the main speakers. Usually you can adjust the crossover frequency and volume to taste, but make sure you get a sub that has these features. It can be tricky to dial in properly, but DON'T just add the sub to the B speaker output. It will not physically harm anything except your ears from terrible boomy muddy bass caused by a bump where the sub and main speakers are both producing bass together. Plus, by eliminating the bass fed to the mains and sending it to the sub - you take the strain off the mains, reducing distortion, and maybe even increasing their lifespan.

Now play with room placement to get the deepest, tightest sound by using a test tone CD

I have the same receiver & was able to successfully connect my KLH powered sub to both A & B speaker outputs (I tried both) & then connect my second set of speakers to the sub & it sounds excellent. Wish you the best of luck!
