Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the
Dolby Pro Logic Surround system. This system is similar to
professional Dolby Stereo decoders used in movie theaters.
By employing a four-channel system, the Dolby Pro Logic
Surround system divides the input signals into four levels: the
left and right main channels, the center channel (to characterize
dialog), and the rear surround-sound channels (to characterize
sound effects, background noise and other ambient noise).

This program reproduces sources encoded with the Dolby Surround.
The employment of the digital signal processing system improves crosstalk and transfers the sound source
more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated.
This program reproduces sources encoded with the Dolby Surround.
Enhancing the "Normal" Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence.
The Yamaha DSP technology is ideally combined with the Dolby Pro Logic to present you incredible
listening experience of the 70 mm film movie theater. This program is ideal for precisely reproducing the
sound design of the newest movies. The sound field is made according to the design of the newest movie
theaters, so the reverberations of the sound field itself are restrained as much as possible. The three
dimensional feeling of the sound field is emphasized, and dialog is precisely oriented on the screen. You
can enjoy watching S.F.X., adventure movies, etc. with this program.
This program simulates the sound field of a jazz or rock concert. By featuring the directional enhancement
circuit, vocals are oriented on the screen and the sound field is widely expanded. Your attention will be
focused on the screen in enthusiastic atmosphere, as if attending an actual jazz or rock concert.
This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically.
This is a small, cozy jazz club with a low ceiling. The sound is very close and intimate.
This program recreates the acoustic environment of a modern church with a high pointed dome and
columns along the sides. This interior produces a very few primary reflections.
In this program, the center seems even more deeply behind the front speaker pair, creating an expansive,
large hall ambience.
Whenever pressed, this switches on/off the built-in digital sound field processor (DSP). When the DSP is
on, a program name illuminates in the display and sound output is from the front, rear and (or) center
speakers. Conversely, no illumination of program name and no output from the rear and center speakers
show that the DSP is off.
FEATURE
Dolby Surround is encoded on the sound track of commercially
available video cassettes and video discs as well. When you
play a source encoded with Dolby Surround on your home video
system, the Dolby Pro Logic Surround mode on this unit
decodes the signal and feeds the surround-sound effects.
The Dolby Pro Logic Surround mode may not be always
effective on video sources not encoded with Dolby Surround.
