What does the the receiver actually do and why is it necessary in these high end systems. Thanks.
An A/V receiver does a number of things, the main one being that it has full audio/video switching. Most monitors have only a few inputs available, but a receiver has many. So, let’s say you have a gaming system, a DVD player, a satellite dish receiver, and a DVR. They would all hook to the A/V receiver, and the signal would go from there out to the monitor. An A/V receiver also has an amplifier built-in to run any number of system configurations: stereo (2-channel), or surround sound (5+ speakers + a subwoofer). An A/V receiver will also have an AM/FM tuner built-in, too, and some are even capable to run your XM or Sirius Radio. They’re pretty darn cool toys, to say the least!
If you have speakers up to your tv there is a great chance in time you will blow the itty bitty amplifier that is in the tv. There is a good reason why the back of the tv gets hot now. Be careful
A good home theater receiver has three separate functions.
The tuner : acts like a radio and brings in the music from the airwaves. The pre-amp : processes audio and video and signals to the proper equipment. The amp: takes the signal from the pre-amp and powers or amplifies the signal so you can listen to the speakers.
