Several years ago, I replaced by Fosgate Four pro logic processor with a Rotel RSP-985 Dolby Digital unit. Although the DD on the Rotel is great, I noticed that, when watching ballgames and other pro logic encoded programs, the effect on the Rotel is virtually nil- all sound comes from the center. I recently had to have the Rotel serviced and, after hooking up the Fosgate as a temporary fix, was reminded of the differences beteen the units in pro-logic- the Fosgate sounded great during the World Series games- crowd in rear, announcer in center.
It sounded so good that I called the Rotel factory and asked that they also check out my unit to see if the pro logic was working OK.
I received the Rotel back and hooked it up tonight. The pro logic is still virtually invisible. Do I just have a lousy unit? Is it worth sending it back again?
Many thanks.

For the longest time, I thought I had the same problem as you, but the problem was intermittent. Sometimes there was no rear information in PL, and sometimes it worked great.It took a while to discover the problem--signal strength. Everything works fine if my cable box volume is turned to maximum. But if someone turns the cable box volume down, I lose the rears.
Feed the strongest volume possible from your source to the 985.
Thanks for your responses, but I don't think the video volume is the problem. I'm using non-variable outputs from the TV monitor's tuner, DVD player, DirecTV Dolby Digital converter box and LD and VHS players. Just to be sure, I taped part of a football game that I was watching on Sunday in glorious DPL over the Fosgate and played the tape on both the Rotel and Fosgate units to make sure I wasn't the problem.
The damn thing is going back to Rotel this week. I bought it when it first came out and suspect that later units were subject to substantial design adjustments. I don't think it's unreasonable to expect a $2000 processor to function properly.
Wish me luck!
I use an RSP-980 (the model before yours) which I believe has the same DPL function as yours. My DPL seems fine (I recall the World Series and NFL Football being pretty cool). I assume you have set the surround levels properly (I use a Radio Shack sound level meter). Also, maybe somehow you're using the variable outs from the TV (instead of fixed). Just some thoughts...
