Deconstructing the home theater pre-processor

Ahhh….the home theater pre-pro….my thoughts on them are basically
summarized by the phase “can’t live with them, can’t live without them”!
Modern pre-pros are the brain of all modern home theaters. An AVR
(audio video receiver) is essentially a pre-pro and multi-channel power
amplifier in one box. Pre-pro’s do a number of essential things without
which it would be virtually impossible to watch movies in surround
sound.
