A:AnswerI had my old Yamaha home theater receiver hooked up the way you describe and I used this method of connection with this new Yamaha RX-V385 and it works just fine.
A:AnswerConnect the red wire to the white input. It should work just fine. If not you'll probably need a y splitter. I have the klipsch 10/300w and that thing is LOUD! Enjoy!
A:AnswerThis Yamaha - 5.1-Ch. 4K Ultra HD A/V home Theater Receiver - Black has a 2 year parts and labor warranty from Yamaha. Keep your sales receipt and register it on-line at Yamaha.com . I had a previous Yamaha Receiver for 7 & 1/2 years that still was working when I decided to replace it with this new receiver. The main reason that I replaced my old receiver was that the new receiver has Bluetooth built in which allows me to wirelessly stream my music from my I-Phone 12 to the receiver.
A:AnswerUnfortunately, you are correct. The optical is an input for connecting other playback devices (TV, DVD, etc). Hopefully your sound bar offers other alternatives.
