Question about Pyramid Audio Players & Recorders
I wouldn't hook anything up except what Yamaha recommends to the speaker output terminals. That's pretty much asking for trouble!

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Let me know if you have any other questions.

Based on your post, the pre-amp is doing its job. What might be the mismatch would be the powered speaker system plugged into the output of the Rotel. Depending on what the "powered speaker system" is, it might be that it is a low impedance such as those used in computers whereas the Rotel requires high impedance to be connected to its output. What could be tried is to connect a regular amp or receiver to the Rotel.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Unfortunately without "surround" processing, the center speaker will not work at all. It sounds like there is a problem with the center channel amp which is part of the receiver. This should be a single amp IC attached to the heatsink. There should be a "test" moe that will send white noise to each speaker in sequence. Try that. If that results in no sound to the center, it pretty much concludes that the center amp needs to be repaired. The part cost for this should be around $25.
