Using Digital Sound Field Processor (Dsp) - Yamaha AV-90PY Owner's Manual

USING DIGITAL SOUND FIELD PROCESSOR ( DSP )
This unit incorporates a sophisticated, multi-program digital sound field processor, which allows you to expand and shape the audio
sound field from both the audio and video sources, for a theater-like experience in the listening/viewing room.
This digital sound field processor has 6 programs; 4 programs for digital sound field processing and 2 programs for the Dolby Pro
Logic Surround sound system (DOLBY PRO LOGIC and ENHANCED). You can create excellent audio sound field by selecting
the suitable program and adding desired adjustments. In addition, when the digital sound field program is in the DOLBY PRO
LOGIC or ENHANCED, the built-in automatic input balance control functions. This presents you the best surround condition
without adjusting it manually.

This program is effective on the play of the 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,comparing with the conventional type. A stable movie sound field is recreated.
This program is effective on the play of the sources encoded with the Dolby Surround.
Enhancing the "Normal" Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
systems of the 35 mm film theater, so widening the surrounded-sound field with greater presence.
This program is effective on music videos and excellent in depth and clarity for vocals. For opera, the
orchestra and stage are ideally recreated, so letting you feel as if you were in an actual concert hall.
This program is designed specifically to enhance mono source programs. Compared to a strictly mono
setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an
immediacy to the overall sound. It is particularly effective when used with old mono movies, news
broadcasts and dialogue.
This program will suit to rock music. A big, powerful sound is reproduced lively and dynamically.
In this program, the center seems even more deeply behind the front speaker pair, creating an expansive,
large hall ambience.
