On Jan 8th at CES in Las Vegas Dolby introduced a new matrix decoding technology, Dolby Pro Logic IIz. This places more surround sound speakers above and to the left and right of the center channel. The technology is supposed to give a more realistic sound envelopment environment. Yet another technology to pay for and make your surreal life a bit more real. Lucky for us Onkyo has just released the Onkyo’s TX-SR607 ($599 MSRP). The first receiver that utilizes the Pro Logic IIz matriz decoding technology.

Dolby has a new surround format: Pro Logic IIz.
Here we go again. Another new format with more speakers, but this time, the “surround” speakers are in the front of the room, three or four feet above the left-and right-main speakers. These height channels are designed to provide a greater sense of envelopment than previous generations of Dolby or DTS surround.
With Pro Logic IIz, some receivers will produce 9.1 channel surround.
