Ok, this is going to be a long post, but hopefully someone who is familiar with these models can help with the problem. I'm having problems hooking up my home theater that was working before I bought my new SACD player. Here's what I have: MX132 Preamp MC7205 Amp Marantz MM9000 Amp Sony 999ES SACD/DVDE Using an optical cable from the 999ES to the MX132, I am able to get the DVD sound working with DTS/Dolby5.1. However, with SACD, I didn't get any sound. After reading that SACD does not use optical output, I plugged 6 RCA cables from the 999ES to the MX132. Then on the MX132, I set the mode to External and the input to CD, and am able to hear audio from all 5 speakers, except for the subwoofer. What am I doing wrong? How should the setup look like? Some general info on the current setup. The MC7205 powers the 5 speakers. The Marantz powers the subwoofer, along with 2 speakers in another room. As I said, when I play DVD/CD, it works fine as the mode is set to either Cinema or Stereo and the input is set to DVD. Any suggestions? TIA!
