Simple Amp/Reciever for 2.1 Setup

[anm]

What class is the amplifier in 3490?

The manual says

This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules.

Does that mean it has a class B amplifier?

regards

Hi Mike,
I am considering 3490 to start a 2 channel rig with floorstanders (Dali Ikon 6 or 7),without sub if possible, but may add sub.
Will it be an issue if full range of freq is sent to main speakers - even when they are bookshelves? I thought it was bad to send full range to sub but it is okay to send full range to mains. These speakers do not have the capability to produce the deepest bass freq so those would get ignored. In mysterious hi-fi world, everything seems to make a difference, but would that be audible, or can blow up some component of the system?

regards

the pre-out enables you to add an external amp, should you need it, in the future. but only when you have hard to drive speakers.

the highpass output will save your main speakers from playing the bass frequencies the subwoofer is playing anyway.

in your case, I would recommend the one with bass management (low pass, high pass)

no i dont think so. but it really doesn't matter what class amp there is inside.

no real issue if you apply common sense to the volume control. when it starts to sound bad (i.e. distort) turn it down.

as long as your sub has a low pass crossover, it is ok to send it a full range signal.

Just curious why it doesn't matter? Why digitals are considered bad (high distortions) compared to class A?
I do not have ANY knowledge about electronics, but I am curious

i don't have much knowledge as well, but don't go basing your purchasing decisions based on what class amp an integrated receiver has ...

watts are watts, and 120wpc whether from class a or b is still 120wpc and the differences if any will be inaudible to your ears

Hi anm. Hi mike. I also don't have much knowledge. But this is what I was recently told:

Class C sounds like crap, period. Class B sounds crappy, except at higher voltages. Class A will not sound better than a well implemented AB, D, G, H, I, etc.

Among my stuff, I've got AB, D, A to B switching.

but +1 to what mike said.
