Surround FX
Pro Logic II is a dramatically improved matrix surround system based on the original Dolby Pro Logic system. In
the case of Pro Logic, there were four channels: front left, center and front right, plus a mono surround channel that
was usually split between two rear speakers. Compared to DPL, DPL II offers two full-range stereo surround
channels, more sophisticated steering logic, high channel separation and an exceptionally stable sound field. DPL II
uses a simple servo circuits used to derive the five channels. And, unlike the synthetic Jazz club, Hall and Stadium
modes found on many AV receivers, DPL II introduces no phony delay-induced echoes, reverb, or tonal coloration.
