Rotel ra-820 amp speaker ports dieing

Try interchanging the speakers. If the right channel works, you have a problem with your speaker.

Hi,
I think RA 12 is not existing type, but RA 12xx types exist.
Please try this link, and I hope you will find the relevant documentation.
Good luck!

If your powered subwoofer could accept speaker level input, like, say a Klipsch KSW-series, you wouldn't need it.

hi
it sound to me that when you biamp and driving speaker and woofer , you are over loading the fuses , suggestions
uprate the fuses till they stop blowing

Lets try the simple stuff first. This whole problem could be caused by a dirty switch contact. Pick up some electronics cleaner from a local electronics shop and spray the switch (from the inside of the unit). Work the switch on/off a number of times then respray one more time. That should clean out any dirt that is there. Try the unit again and hopefully the problem is resolved. If not, then the switch itself may need to be replaced. When you get the cleaner, get one that contains a lubricant as well. This will help to prevent the problem from coming back again.

some amps have a switch to bridge them rather than wiring a bridge meaning output is mono check to see if yours has this switch if you do simply put back to stereo

Hi,

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.

Since it is a Rotel, it is a good unit and worth fixing. At this point, you need to take it to a good repair shop and let a qualified tech look at it. There are no user serviceable parts inside and if you go poking around in there, you WILL make the problem worse. Rotels' are nice units and represent a good value in stereo gear. Take it to a reputable repair shop that repairs Rotel under warranty. If thats not available to you, then a good repair shop should be able to get you going. Good luck...Rob

Instead of replacing you can try and clean it. There are a lot of good contact cleaners out there.

Try only A speakers.
