If anybody has any first-hand experience with these inputs, I’d love to hear about it.
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?

I’m not sure if the reply was AI generated or not, but he’s not wrong. It’s a very rare beast, and the "idea" was to sell amps to enthusiasts with existing receivers. It was rare in those days to have a receiver with a true pre-out so these amps would provide a relatively high resistance load (800 Ohms I think or more), letting your receiver cruise, while using all the tone and volume controls. I’m thinking of the days of dbx speakers and a mail order catalog back in the day. Fun times. Alternatively they could be used for multiple zones, letting you use your receiver for the main speakers, and having additional speaker pairs. Again, idea was to use the receiver's tuner/preamp section. A typical Tape out/In would not work in these cases since they were before the volume and tone controls. |
You are correct, @sls883 gave the answer, I'm glad you went a bit further with the explanation, I never heard of such a thing, makes sense in the timeline of things.. |
