Hi there

You have a DC offset condition occurring on the speaker output of the amp. This usually means that some components have blown in the output stages. Be careful turning the amp on when this is happening, if the cones of you speakers are blowing out and stay out... then they may be damaged if left in this condition too long(more than a second!!) You will need to take the amp to a serviceguy... most of these sorts of repairs need expert attention.

10 years and first problem to repair. When you turn on and select DVD or any other selection a very loud cracking noise comes through right speaker only. So loud (with volume tuned off too) that I fear...


I think your receiver is damaged.

Try this.

Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right"

Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly.

Disconnect both left and right speakers.

Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on.

IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine.

Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on.

IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver.

If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

When i turn on my reciever it imedietly clicks and goes to stand by


Hi,
This usually means that the amplifier is "clipping" and therefore is seeing a short.
This can be several issues, I would invite you to check the following:
1- Make sure no speaker wires are touching behind the Onkyo receiver. When hooking up speakers, it happens frequently that the speaker wires may touch and create a short, which will cause a "clipping" or a short on the receiver.
2- New Receiver are very sensitive to higher or lower impedance speakers. Make sure that the speakers you are hooking up to the receiver are not higher than 8ohm's, and lower than 6ohm's or the amplifier will eventually clip.
3- If this is a problem that started happening recently but has been working in the past, I would look back at what was done in the past to maybe have modified to your system. Are your speaker wires in the wall? Have you accidentally nailed a nail in the speaker wire, that can also cause a short.
4- If the above doesn't work, start from scratch. Unplug everything behind your receiver and simply plug-in the unit to a power outlet and turn it on. If the amplifier doesn't short, then there is something that your are plugging into the unit that does not agree with one another. If that is the case, start plugging in one thing at a time and follow the process of elimination. If the unit shuts off right away and nothing is plugged into the unit, the receiver might be defective and must be sent in for repair.
This is the longest solution but the more prominent to find the root of the problem.

Hello, I have a Sherwood RX-5502 and currently have a pair of 8Ohm speakers hooked up to the SPEAKER A terminals. Can I hook up a pair of 4Ohm speakers to the SPEAKER B terminals without issue from...


The statement on page 7 might allow enough wiggle room for a single pair of 4-ohm speakers used alone. Procede with caution and don't try to blow the walls down with them. Monitor for excessive heat or strain and if it clips or self-protects back off.

Sony str-de345 this keeps on blowing fuse


Disconnect all speakers at the receiver and test again. If it still blows a fuse, it needs a new power supply and needs to be serviced. If it does not blow the fuse, follow this:

The most common problem found on FixYa for Audio Video2_bing.gif Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Keeps turning itself off


If Both speakers are working at a low volume and you turn it up and it clips and shuts off you have one of 3 problems. you have over driven your speakers and one has shorted the voice coil but still will work at low volume, its a overload protection for ohms short in receiver. unhook each speaker and turn balance to the one hooked up and turn up receiver if it shuts off do the same with other speaker to determine which side is bad. 2 speaker wires are touching at speaker or receiver. 3 a bad receiver output transister. Good luck.

Hi My denon avr 2600 keeps clips when turn on


Check the polarity (+/-) of the speaker wires. A typical receiver will try to cut the power to the speaker if it's feeding it too much power or too little power to preserve the speaker and/or receiver. That may be the clipping you're hearing. If the wires are reversed, this can cause the same thing.

Can you run 200watt 6ohm speakers on the RX-V490


Hi I have just read the specs on about your Yamaha system and you cant run 6 ohm speakers to your amp. You have to impedance match the speakers and the amp otherwise the speakers will "blow". So you need some 8 ohm speakers, the wattage of the speakers doesn't particularly matter as long as they are not too weak or too powerful becasue the amp will drive the speakers no matter what but if the speakers are of a low wattage then the amp could blow the speakers if it is turned up too loud. The specs of your amp are given in the link below.

Denon receiver shutdown


Try turning down your tone controls. Like your bass, treble, or your equalizer. If you hear too much tinny or hissing sounds, the treble has to be turned down, or turn down the upper bands controls on your equalizer to the optimun level. If you hear too much bassy sounds, your bass control has to be turned down, or the lower band controls has to be turned down to the optimun level. If you are planning on turning the volume up, you may have to turn down some of the tone controls to the optimun levels, otherwise, your receiver may shutdown, or you may blow fuses in your speakers. Also make sure you speaker wire polarity is hooked up right. Red wire on the + red terminals, and the black wire on the - black terminals. Also don't have the volume turned up too high to the point where your receiver would have clipping or distortion, or else your receiver may shutdown, or you may blow fuses in your speakers.

If this don't help, then there may be something wrong with your receiver or your speaker.
