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.

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.

What would make the sound turn on and off repeatedly when I raise the volume past about 17.


well, if you have aftermarket speakers with no amp, the radio may not have the power the speakers need and it clips at that volume to protect for damage. if you have factory speakers, I don't know what it would do that, the speakers would blow before the radio would clip if they were factory because the radio would have more than enough power to push them.

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.

How many ohms? 6 ? 8 ?


David,
The AT line were all rated at 3.2 ohms. Any amp or receiver rated to handle 4 ohms loads will work. The fuses and tweeter breakers are sensitive to clipping so most low cost amp's and just about every receiver will cause undue clipping. CV stated that increasing the fuse a half amp would increase the time before blowing the fuse or breaker but that will only cause additional harm to the voice coil.

Speaker wire


Use the same gauge that is supplied for the rear. Probably 24 gauge.Do it with the power off. If the wires touch with the power on the rear output IC will blow. Good Luck

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.
