Dolby Pro Logic IIz: Surround Sound Goes Vertical
Dolby Pro Logic IIz processing is an enhancement being implemented in some home theater receivers that extends surround sound vertically and fills the space above and in-front of the listener. Dolby Prologic IIz offers the option of adding two more front speakers that are placed above the left and right main speakers. This feature adds a "vertical" or overhead component to the surround sound field (great for rain, helicopter, plane flyover effects). Dolby Prologic IIz can be added to either a 5.1/5.2 channel or 7.1/7.2 channel setup. It is also compatible with two-channel and surround sound sources, including, if applied correctly, Dolby TrueHD and DTS-HD Master Audio.
When added to a 7.1 or 7.2 channel setup, you end up with both surround back and front height speakers - However, you would then need amplification for all 9 channels. Since some home theater receiver only provide amplification options for 7.1/7.2 channels, you must forgo the surround back channel option when using the Pro Logic IIz feature when using a 7.1/7.2 channel home theater receiver. This means that you are actually using a 5.1/5.2 channel setup and adding the Dolby Pro Logic IIz height channels to obtain a 7.1/7.2 channel setup.
In order to use Dolby Pro Logic IIz to is maximum effect, the front height speakers should be mounted approximately 3ft directly above the front left and right main speakers. In addtition, to retain the character of the original surround sound mix, the speaker level settings for the height channels should be set slightly lower than that of the main left and right front speakers. However, you tailor the speaker levels to your preference.
The Motivation Behind Dolby Pro Logic IIz
The motivation that guided the development of Dolby Pro Logic IIz is observation that humans hear more from the front and sides than from the rear.
In other words, in the effort to create an optimum surround sound listening experience, it is more advantageous to emphasize sound coming from the front, sides, and above the listener than it is to add more emphasis from sounds originating from the back of the listener.
In the case of current surround sound technology, the observation is that the traditional 5.1 channel surround schemes now commonly employed provide enough rear audio information for the listener, and adding one or two more surround back channels, as is promoted with current 7.1 channel home theater receivers, really doesn't give the listner that much more of a surround sound experience. In addition, in smaller room environments, adding one or two surround back channels is physically impractical.

Related Technologies to Dolby Pro Logic IIz
Although the familiar Dolby brand name garners attention to Dolby Pro Logic IIz amongst consumers, there are similar technologies from other companies that are also available.
Yamaha Presence Yamaha offers a similar technology on some of its home theater receivers called Presence. This surround sound scheme also employs the addition of two front height speakers to add a full surround experience from the front and above the listening position.
