This receiver incorporates 4 different sound modes to let you enjoy surround sound with a wide variety of program sources
The Dolby Digital (AC-3) and Dolby Pro Logic surround sound let you enjoy theater-like surround effects when you play Dolby
Digital (AC-3) and Dolby Pro Logic program sources (like Laserdiscs and DVDs). Dolby 3 Stereo creates a panoramic frontal
sound field while keeping dialog on screen. The Digital Signal Processing (DSP) modes let you create a variety of different sonic
environments from almost any type of program source.
To obtain the best possible surround sound, be sure to complete "Surround set up" before using the surround modes.-

Dolby Digital (AC-3) provides even better sound quality,
greater spatial accuracy, and improved dynamic range.

format designed to provide theater-like surround sound
