Microprocessor User Re-set --- What is it?

I'm comparing a few Denon receivers. One of the last subject areas in the comparison is labeled "Microprocessor User Re-set". I have no idea what this is. From the search results I've found it sounds like it has to do with savings user settings from power on/off/on and possibly avoiding damage from power surges, but it's hard to tell really. Does anyone have any idea? If it helps, the different values that Denon provides for the different receivers are "Y/pg. 64", "Y/pg. 55", and "Y/pg. 60".

Next, does this kind of microprocessor from receiver to receiver really matter in the whole scope of things?

Thanks in advance for the help,
Jeff

It sounds like you are referring to the reset to default feature. If something happens where you lose a feature or setting and you don't know how to restore it properly, you can restore the receiver to it's factory default programming. I had to do that to my Denon once on the advice of my dealer and haven't had any trouble since.

If you are thinking of something else, let us know.

It's not a bad idea to reset the receivers that have this immediately after unpacking it.

All microprocessors have a reset function but not all manufacturers give it to their customers. Microprocessors can lock up after power spikes and this lets you go back to a setting when everything worked, like a computer's setting for the same thing.

"Next, does this kind of microprocessor from receiver to receiver really matter in the whole scope of things?"

What are you asking? If the microprocessor brand and part number matter or is it actually needed?

I'm distinguishing features among different models. So I was wondering if the microprocessor one model uses was any better than those that the others use, and if it was anything I should be concerned about when considering each model. But seeing as it is just for resetting to default settings, I can't imagine it makes much of a difference which microprocessor each receiver uses.

Thanks guys.

Some processors will obviously do more than others but all that really happens during a reset is that one or more pins are connected to ground to voltage and the settings go away. The processors are usually non-volatile memory chips and unless a spike or static discharge occur, it's there for a long time.

"But seeing as it is just for resetting to default settings, I can't imagine it makes much of a difference which microprocessor each receiver uses."

The processor isn't used for the reset- it's usually a built-in function but to make it harder to reset it accidentally, multiple button presses are needed.
