Adjusting the Sound
Pro Logic Emulation Mode (EMU)
The Pro Logic emulation mode offers users the same robust surround processing as original Pro Logic, in case the source
content is not of optimum quality, or if there is a desire to hear the program more "as it used to be". When this mode is
used, it is called Pro Logic, as before. There is no "Pro Logic I" mode. The Pro Logic emulation mode is optional. Dolby
does not require PLII products to use the original Pro Logic decoding algorithm. However, if the DSP contains the original
Pro Logic code, and if the product maker would like to use it, this is quite acceptable and even encouraged. A product
must not offer both original Pro Logic and the Pro Logic emulation mode.
Matrix Mode (MATRX)
The Matrix mode is the same as the Music mode except that the directional enhancement logic is turned off. It may be
used to enhance mono signals by making them seem "larger". The Matrix mode may also find use in auto systems, where
the fluctuations from poor FM stereo reception can otherwise cause disturbing surround signals from a logic decoder.
The ultimate "cure" for poor FM stereo reception may be simply to force the audio to mono.
