Does Dolby Pro Logic IIx replace Dolby Pro Logic II?

will not! While Dolby Pro Logic IIx uses the same core technology as Dolby Pro Logic II, its functionality extends. Dolby Pro Logic II will continue to be the preferred choice for "two-channel 5.1-channel" decoders. Dolby Pro Logic IIx will be used by manufacturers in hardware products and provide 6.1 and 7.1 channel output capability.


The "Movie Mode" or "Music Mode" in Dolby Pro Logic IIx allows you to adjust the listening effect. "Music mode" also provides up to three user adjustment options:

Dolby Center Width: Adjusts the balance of the vocals in the center and front left and right channels; Dolby Panorama: produces a coherent, more encompassing surround Dolby Dimension: Adjusts to produce a deeper or lighter surround sound field.

There is also a special "Game Mode" in Dolby Pro Logic IIx that can turn extremely powerful special effects into surround channels.

The difference between the Music Mode and the Movie Mode.

Surround sound programs are mostly film programs. Most TV shows are also produced in the same way as movies. When the program is mixed in surround mode, the sound engineer will monitor the playback with cinema or home surround sound decoders. The movie mode is the standard decoding mode for all surround-sound encoded programs.

Music programs are different, this program is generally mixed by the stereo way, the recording engineer does not monitor its production in the surround mode playback. When a music program is played through a surround sound decoder, the effect is not necessarily optimal. This is because the signal source corresponding to the decoder in the cinema mode should be a surround-coded signal. In the Dolby Pro Logic IIx music mode, the decoder can bring highly natural and balanced multi-channel surround effects to programs that are not specifically produced for surround sound playback.
