Dear members, I own an Onkyo 3500 in good working condition but wish to connect the rear speakers wirelessly. Is it possible, if yes, please guide me on how to go ahead as I am clueless about this. Kindly guide.
It is possible but cannot say if it will be worth the efforts and cost.
You will need a separate stereo amplifier kept at back. A wireless audio transmitter which will get signal from AVR surround speaker out using high to low level impedance converter. The transmitter will send signal to the receiver end of it connected to the stereo amplifier to which the surround speakers will be attached.
I think it will be better to get the wiring done underground next time you go for a white wash
