Question about Rotel RMB-1095 Power Amplifier
Hi. I recently set up a home theater audio system that has a Rotel THX Amplifier. When the amp starts up it has a diagnostic panelon the front that shows status for left, right and center channel checks. I was testing it with a DVD and noticed no center channel sound was coming out. I checked the speaker wiring and turned the sysytem back on. It was then that I noticed the diagnostic light for the center channel was out. Just wondering if this thing is ready for the repair shop, or if there is something else I can do to reset it. Thanks.
Also make sure you have the DVD setup for center channel as well. It and the subwoofer can be disabled in most DVD players. BMW

If you say you checked the wireing ,did you check the speaker. disconnect on of the other speakers and connect up the center to see if you get sound. still no sound speakers bad. Got sound try unpluging unit for a couple of hours then try it again. still no center . Time for the repair shop. Good Luck

I'd suspect that one of the two output transistors on that channel has gone bad. If you are unsure how to test or troubleshoot this, then you might try replace both the NPN and PNP outputs and catch the bad one that way. If your amp uses an output module then you would of course have to replace the module which would replace all the output transistors on both channels. Good luck. Another thing to look out for, is the emitter bias resistors. They are the large white ceramic ones near the outputs. Sometimes one of those will open up too. They will be of a very small resistance value like .5 ohms (point five ohms) or something in that general ballpark, and have a wattage value of typicaly 5 watts. So they are pretty big resistors. Be sure to check them all even if you do find a bad output transistor. They will often go out with the transistor. Good luck.

If you are not using the 12v trigger between pre-amp and power amp make sure that the trigger switch on the rear of the RB-1070 is set to off

Tips for a great answer:
Connecting an Amplifier / DVD Home Theater
TV Rear Panel
1 Audio Cable (Not supplied)
Amplifier/DVD Home Theater
1 Connect Audio Cables between the
AUDIO OUT [R-AUDIO-L] jacks on
the TV and Audio Input jacks on the
Amplifier / DVD Home Theater.
When an audio amplifier is connected
to the AUDIO OUT [R-AUDIO-L]
jacks: Decrease the volume of the TV
and adjust the volume level with the
Amplifier's volume control.
Each Amplifier/DVD Home Theater has
a different back panel configuration.
When connecting an Amplifier/DVD
Home Theater, match the color of the
connection terminal to the cable.
