Dolby Surround AC-3 is the multichannel audio coding that forms the basis of Dolby Stereo Digital found in the best movie theaters. Technically, it includes five separate discrete, full-bandwidth channels plus a sixth subwoofer channel. The stereo surround effect of AC-3 results in an expanded sense of depth, localization and overall realism.

To obtain these effects in a home environment, it is necessary to compensate for the differences between a public movie theater and a home media room. Yamaha combines Dolby Surround AC-3 with its own DSP to solve the problem and preserve the sound positioning designed by the movie sound director. When playing AC-3 encoded discs, Yamaha utilizes three sound fields (presence and surround L/R) to acoustically enlarge the sound field to the acoustic size of a movie theater.

Yamaha designed and incorporated this sophisticated and powerful new very large scale integrate circuit chip. It supplies 33% more Cinema DSP processing power than those used in the company' s previous model the DSP-A2070.

Extremely accurate Dolby Pro-Logic decoding with Yamaha's YSS-213 LSI.

Accentuates bass by 7 dB at 70 Hz for systems without subwoofers.

For easy viewing of controls and adjustments. LCD display has been enhanced to provide better contrast and better readability. Fold down front panel door maintains unit's uncluttered look.

Built in test tone generator provides a sequential sweep of the channels to establish proper balance. A subwoofer test tone generator provides a level for adjusting the subwoofer output so that a listener can match the room and the rest of the system.

This parametric and high shelving filter allows timbre matching and equalization for all speakers.

Lets you program and control additional components such as a VCR, Laserdisc player, or TV.
