By adding front height channels, Dolby Pro Logic IIz creates a 7.1 or 9.1 playback system that enhances the spaciousness of music, movies, and video games, bringing a new dimension to surround sound listening.
An additional pair of speakers located above the front left and right speakers enables Dolby Pro Logic IIz to introduce a vertical component to the horizontal soundfield of a conventional 5.1 or 7.1 surround sound system.
Because it processes only nondirectional sounds for the height channels, Dolby Pro Logic IIz maintains the integrity of the source mix, so the effects are always appropriate to the material. This added dimension complements the sound from the rear surround speakers, increasing spaciousness while staying true to the original intent of the content creator.
As is the case in existing Pro Logic IIx technology, the height extensions don’t require new kinds of program content to drive the height channel outputs. Instead, the extensions are designed to effectively add depth and dimension to existing program material.
Dolby Pro Logic IIz also incorporates an encoding aspect that enables content providers and game developers to maximize the added dimension by creating entertainment with height elements of near-discrete quality.
With Dolby Pro Logic IIz, rain in a movie sounds like it’s actually falling on the listener’s roof, concert videos bring a more intense sense of being at the performance, and orchestral works deliver more palpable depth, power, and connection. That’s a home theater experience your customers won’t soon forget.
