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.
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
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
that the listener and often the engineer running the sound mixing board
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,
