Question about Onkyo TX-SR501 Receiver

1 Answer

Power loss While watching movies and listening to music the reciever will shut down for no apparant reason. The unit is not hot nor is it enclossed whithin a cabinet. I purchased a small axial fan and placed this fan on top of the unit to move air around it thinking it was gatting to hot. This did not solve the problem. The reciever shuts down and powers off after ten to fiftenn minutes of use.

Re: Power loss

Its possible that one of the speakers wires are shorting out or touching the case of the unit (leads to protective shutdown).

Dennon gets hot shuts off

how are your four outside speakers hooked up? If you have four speakers hooked up to only two output channels on the receiver, the receiver is sensing a short and shutting down to avoid damage to the amp.

AVR SR6004 switches off while BD player is playing. What do I do?

There are two circumstances that I know of that a properly installed unit such as your Marantz would shut down. So here is the Theory and Data I know of.
A Your receiver has a great deal of amplification power. If it is in a closed cabinet without excellent ventilation, it will shut down if used at high volumes because because over heating. Because of it's very high power, when played loudly, it generates excessive heat.
When watching certain movies the BD player may be over-driving the limits of the amplifier section of your receiver. Page 78 of your owner's manual addresses this. Here is a link to download the manual from Marantz.
B There is one other very important thing I should mention to you. When people use high powered equipment and initially turn up the sound. After a short time, the mind turns it down. What next happens is the reason professional musicians and sound engineers often have permanent hearing loss after a relatively short time.
What tends to happen is that the listener and often the engineer running the sound mixing board at a concert(after a certain period of time) believes the sound is not loud enough when it really IS loud enough. (this tricks the audience as well) and engineer turns it up. After turning it up, his mind (and the audiences') turns it down mentally and they again think and agree that it not loud enough and then again, the volume level is turned up. And up. And up. The only reason I'm not deaf is that I discovered this when I was building sound systems as a kid. I also studied about it. So please be careful when you play things loud. Permanent hearing loss starts to occur at the very high frequencies and rolls down from there over a period of time. Hearing loss can start to occur in just a few hours at 110 decibels. permenant hearing loss is exactly just that. Permenant! It just doesn't come back. If you use this information, you will enjoy hearing music for the rest of your life.
I hope this helps,
Best Regards,

My kenwood vr615 reciever had the volume turned up, unit shut down and now when it gets to a certain volume that is much lower than normal it will turn off and the stand-by light will flash, I have to turn...

hello ,i strongly suspect the units protect circuit is sensing a speaker problem.Listen to each speaker to see if all the drivers(woofer,midrange,tweeter) are working and if so are any of them sounding distorted.When an amp is damaged it wont play at all,sounds like a bad speaker to me.

sounds like you have the polairity reversed on the speakers
and yes it does make a difference
check polairity also make sure unit is well ventelated
you wouldnt use your compouter if it was inside a card board box
so make sure the reciever can breath also
recievers get too hot and they start blowing chips off the board

Avr Shuts down at high volume

It does that because there is a safety feature in all the newer devices. If your system is turned up to high you would blow your audio outputs or speakers. That's why it shuts off.

speaker terminal are short circuit,switch power off connect speaker properly then switch power back.

Denon AVR 2802 - Unit Turning Off

If DIGITAL sign blink, this mean DSP board is defective. It will cut the sound on the AMP section. DSp is maybe defective.

Shuts down at high volume

If you have your reciever in an entertainment center that is enclosed or a tight fit for the reciever you need to remove it and put it on top of the center. I have a VR407 and it was doing the same thing. This keeps your unit much cooler and the overheat relay will not turn it off. also I found it much easier to add or wire components much easier.
