A surround sound processing technology that can extract center, left, right, bass and stereo surround channels from a stereo source. Pro Logic IIx can additionally extract two rear surrounds from either stereo or 5.1 sources, and Pro Logic IIz further extracts front stereo height channels.
Multiple modes may be offered by the system: Movie mode, Music mode and Game mode.
PLII works fundamentally as a matrix decoder with servos that accentuate the directionality of the current determined dominant signal by negative feedback in the other channels. The surround channels are fed by signals of inverted phase while the height channels contain uncorrelated, ambient signals.
Although PLII works from basically any stereo source, stereo programmes can be specifically encoded for surround decoding by PLII with matrix encoding. These programmes may be branded with the "Dolby Stereo" or "Dolby Surround" logo.
DO NOT believe Eazy-X's definition. It sucks so bad.

Get the dolphin pussy mug.A term used to describe a maneuver in first-person shooters (specifically Call of Duty 4 and Battlefield 2) where a player jumps out of concealment or when under fire, then immediately, once on the ground, goes prone and returns fire. In the case of ambushing another player, the dolphin dive takes advantage of the speed of a running jump to surprise a player and throw off his aim and the concealment of the prone position that follows to prevent taking fire once the enemy becomes oriented. In this case, a single combatant is sometimes able to take on multiple enemies at once.
