Amp with speaker INPUTS?? Please explain!


So, I was browsing an amplifier manual, as one does, and the diagram shows four spring clips (R+ R- L+ L-) labeled Speaker IN. (I couldn’t figure out the image hosting thing, otherwise I’d post pics. It’s an AudioSource Amp 300, and the manual is short and easy to find.) I’m not familiar with component connections beyond a couple pairs of speakers and maybe an EQ. But this puzzles me. Can someone please explain when you’d use this? The short “explanation” In the manual is woefully inadequate. 
 

I’m especially interested to know if speakers are at the other end of the wires that connect here. I mean, that would make no sense since speakers don’t send anything that direction, right?

Before posting this I typed into Google, “why does the AS amp 300 have speaker inputs?” And the AI generated reply was near word for word your post. "

So what? You asked a question and he was kind enough to get you a valid and helpful answer. Don't see why you would chide someone that is trying to help.

It was word for word.  Doesn’t mean that it wasn’t good information.  You said that you didn’t know what the speaker inputs were for and my post answered your question.  I didn’t figure that I could say it any better than Google did.

 

If you use the speaker inputs on the AudioSource, you would connect the speaker outputs from a receiver (the terminals normally used to connect the receiver to the speakers) to the speaker inputs on the AudioSource.  This is an amplified signal not typically used to connect to another amplifier.  

 

When I first read about the AudioSource, I figured that it was a feature used to boost wattage from a low wattage receiver.  As Eric mentioned, there was a time when watts was king.  I think it was a bigger priority than sound quality. I lived through those days....

 

To those who think I’m being rude:

I’m working from the assumption that users on this board are savvy enough to know how to do a Google search. Myself included. So when that doesn’t give you the info you’re looking for, this forum is the best next step. The value of this forum, as I see it, is people with first-hand knowledge sharing it. Ask yourself if you’d be satisfied if someone’s answer to your question was a cut and paste Google AI overview. I doubt it would be.
