Dolby Pro Logic Iiz - Pioneer VSX-1122-K Reference Manual

Various Speaker Settings
1122 922
Previous AV receiver models only allowed surround back
speakers for a 7.1-channel layout (Fig. 1).
This year's lineup provides more options in terms of speaker
placement. Combine front wide speakers (Fig. 2) with Pioneer-
original Wide Surround mode to enjoy more spacious sound in
the front. Or place front height speakers (Fig. 3) and use Dolby
Pro Logic IIz for vertical-spreading sound.
Wide Surround Mode
1122 922
Pioneer's Wide Surround Mode creates sound with highly dense
motion feeling around the front and the sides. Wide Surround
Movie provides motion feeling in front, while Wide Surround
Music creates a wide-spreading sound field in the foreground.

Dolby Pro Logic IIz

1122 922 827 822 522
Dolby Pro Logic IIz realizes more spacious
surround sound by adding front height
channels to the conventional 5.1ch/7.1ch
speaker settings. The enveloping sound with additional depth
and dimension creates a lifelike listening experience. Dolby Pro
Logic IIz does not require special contents, and works with
existing soundtracks.
