Hi, I recently purchased a SACD player that only outputs multichannel through 6 RCA cables. However, my received only accepts multi-channel inputs through a digital coaxial or optical cable. Is there any solution that will allow me to splice the RCA cables into a single digital output?
Indeed it is. The only way to get digital output from SACDs would be the hybrid SACDs which include both formats.
Unfortunately, the only way for you to use the analog outputs would be to get a receiver that can accept these inputs. That is the only available converter out on the market.
