A:AnswerI would imagine that yes, it should work. Hard to say definitively without seeing what you have of course. But this being a 5.1 system that connects with basic speaker wires, I would say you shouldn't have too hard of time connecting everything. Also I'm assuming the sub woofer you have connects via RCA.
A:AnswerYes, from your TV to the receiver you'd run an HDMI cable from the TV's ARC (Audio Return Channel) to the Receiver's HDMI ARC. If your TV doesn't have ARC you'd use the TV's optical out. This transmit the sound (audio) from the fiber to the TV to the receiver. You can then adjust the receiver's control of the sound to you liking i.e. 5.1 surround, stereo, etc...
p.s. your fiber goes to the TV...not the receiver.
A:AnswerMake sure your tv is set to theater. As long as the Blu-ray player is set to audio over hdmi it should work. Check all the settings and don’t skip around. Hope that helps
A:AnswerI'M not sure it can be use in that configuration, its a 5-1 receiver. The Yamaha 7-2 receiver can. The Best Buy web site does give you all the configuration.
A:AnswerYes, you should be able to connect via Bluetooth although I would contact Yamaha for verify compatibility with your make and model subwoofer...
