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!
