5 Things to Look for When Buying an AV Receiver


For audio-video novices, just setting up a home entertainment system so that all of the components are connected is hard enough, let alone determining whether the components are properly functioning.

Many receivers make that job a bit easier by offering automatic speaker calibration, which allows the receiver to analyze and automatically adjust the sound of connected speakers. By sending test tones to the speakers and subwoofer and monitoring the sound using a microphone, the receiver can determine speaker size, measure the distance from each speaker to the listener and check whether the components are properly connected. The technology works for both surround sound and traditional two-channel home entertainment systems [source: Guttenberg].
