Question about pre-amps
Im pretty new to the forum, but im in love with my HT.
Even though I love my HT, and know a little more than the average human, im still pretty clueless about the whole pre-amp concept.
What exactly is a preamp? I know it hooks into your reciever, but is it an actual amp, or do you plug an amp into it?
You can use other recievers as amps? If I have a 100 x 5 watt reciever, but Im not using it, I can hook it into my primary receiver and use it as an amp just for my sub?
Also, can ANY receiver have an amp hooked into it, and can any reciever be used as an amp?
Thanks for your help.
