Question about Rotel RMB-1095 Power Amplifier

Help with my power amplifier

When we turn on our Rotel RMB-1095 Power Amplifier we get a LOUD buzzing sound (like feedback) out of the centre channel speaker.
Also no sound works on the other speaker. I read the owner manual to hook it up right. I followed every step. I even went through each step to make and sure I did it right. What could be wrong?

This sounds like there is a problem with the final output stage. Is this a new amp? Is it under warranty?

No sound to remote speakers in dining & deck areas.


Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

Hi, I have a Rotel 1050 receiver that I am trying to hook up to a NAD 2400 THX amp. I do not know how to "bridge" the connections so that the Rotel amps are not disabled. Any help is appreciated.


I think the best solution is to remove the jumpers from the Pre Out - Mon In connectors, insert a pair of RCA Y-adapters and plug one end back to the Mon In while the other ends feed the NAD (Page 15 of the manual available at Retrevo.com) . The Rotel's volume and other controls will still be in charge of the NAD.

The manual fails to mention looping the Pre Out back to the Mon In to enable the Rotel's amp to still participate in the program material.

I have a problem with my RA-9808X. A guy I know tried connecting some small speakers from a car with it, and he probably did something wrong. Now it doesn't light up when I plug it in and turn it on...


All I can say to you is look around where the mains goes in very carefully. Fuses are sometimes hidden or in a case or cover of some kind. Sometimes amps use fuseable resistors. If the PC board is marked up look for resistors with "RF" or different indication to a normal resistor. Otherwise fuses will have "f" markings on the board. Remember the power supply part might be enclosed in a metal case with holes in it, so might be hard to spot fuses.

Rotel power amp


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

Right speaker jack not working


Why would it die from being in storage? Oxide or corrosion on contacts, volume potentiometer, Tape Monitor or other switch contacts.

Try manipulating all controls and switches throughout their ranges many times and see what happens.

Check the heaphone jack. If it works so does the right amplifier. While you're at it, insert the headphone jack multiple times to cycle its contacts, too.
