A:AnswerYes, it will connect to your Bluetooth phone and play your music. It will receive your Bluetooth signal but it will not send out a Bluetooth signal to connect your headphones to the sound coming out of the system.
A:AnswerWhy are you trying to hookup the DVD player when your Blu-day player can play both blu-rays and DVDs?

A:AnswerI have not found this myself yet. There is a level calibration of +/- 12 db for each speaker, 15 db for subwoofer and an equalizer trim adjustment for (I thought I adjusted +/- 10db) +/- 6db for various frequencies. I did just consult the advanced manual on this question.
A:AnswerI would not reconmend connecting these wires without knowledge of the system. The TX-NR676 is designed to drive a 5.2 or 7.2 speaker system. There should be 5 pairs of wires for 5.2 speaker system. 7 pairs of wires for 7.2 speaker system. Plus 1 additional pair if using zone 2 speakers. The picture looks to be a volume control circuit for remote speakers.
