Yamaha RX-V630 Receiver Logo
Posted on Feb 07, 2008

Optical Audio Howdy My DVD and my Tivo Series 3 each have optical audio cables. Are these in place of the RCA based cables or must they be used in conjunction? I get audio with the RCA cables but none with the optical, although the red light goes through.

    Thank you auddoc. As a side note, with my Yamaha RX-V630, I was unable to hear any sound with the optical cables. As such, I Phoned Yamaha Tech Support. They had me reset the stereo, and like magic, the cables worked flawlessly! Cudos to yamaha even though the unit is several years old and likely discontinued!

The digital cables should always be used if your whole system allows for it. Generally you have to go through the setup procedure on whatever brand of receiver/ amplifier you own. You didn't mention a brand or model and it doesn't matter. The advice would be the same. Read the owner's manual on how to do this. Digital inputs, such as optical or SPDIF ( the little single RCA plug that also says digital) can usually be set to default ( always on) or may have to be selected manually, each time, depending on the setup procedure. Try both analog and digital. If one sounds better ( it will be very subtle) that generally means the converters in that piece of equipment are better by some degree. Rule of thumb is to use digital between pieces of gear, whenever possible, if only for less noise, caused by RF emission pickup. And please don't buy the overpriced "Gucci" digital or analog cables, like Monster at retail pricing, no matter what **** , the salesman may spout. It's similar to joining Scientology- if you believe unsubstantiated psuedo-science crap people tell you.... you will probably get what you deserve.

    Glad they were able to help. Yamaha has always been underrated for both gear and service. Enjoy your audio system.

    On a side note: most receivers do not have a reset mode. If they do, it's accomplished by simply unplugging the unit. I imagine you had to powe-up while holding down a button(s) or something like that, to do the reset?

    Ciao,

    Gregg
