An amplifier is a powerful piece of equipment that takes a small signal, and amplifies it then outputs it to speakers. Why is this necessary? Well, without an amplified signal, you won't get enough power to make your speakers work. You'll need more than an amplifier to make your setup work though. You're going to need a preamp/processor, the amplifier itself, and most importantly you need speakers. Home Theatre Concepts is here to help make the selection process easy for you!
