*In addition to the six channels (Main L/R, Center, Rear L/R, Rear Center) there is a subwoofer output (hence 6.1-channel format compatibility) and two front effect channels (a total of 9 DACs). The front effect channel signals, unique to Yamaha CINEMA DSP, are mixed with the main channel signals to achieve more precise separation of dialogue, music and effects on the front sound stage and a superior sense of presence as compared to other systems.

are smaller (2/3 previous types), so signal paths are shorter and there is more space for the large power supply components. Digital interference is reduced and impedance is lower as well.

Accurate Touch Volume Control No one expects more from a volume

control than up and down — except Yamaha. We decided that controlling the volume could be made both easier and more accurate, and the result is the Accurate Touch Volume Control. It lets you make delicate adjustments within a narrow range, yet enables you to move to very high or low levels more quickly.

Its extreme accuracy is due to a high- signal-resolution analog design in conjunction with an ultra-precise digital control circuit (Yamaha original YAC-520 LSI). The wide control range extends from 0dB to 99dB, with narrow 0.5dB steps throughout the entire range for delicate control, even at low volumes.

In this format, the back surround channel is matrix encoded into the left and right surround channels. For playback, the three channels are separately decoded.

Improved version of Dolby Pro-Logic for music and movies. With a more intelligent matrix decoder, it is suitable for both stereo and surround-encoded sources. It offers “bass management” as well as the option of incorporating “width,” “dimension” and “panorama” controls.

Dolby Digital

Dolby's latest surround format, this is Dolby Digital with an added center rear channel. The rear center channel is actually matrixed into the two rear channels, and is extracted upon playback. (Formerly called Dolby Digital Surround EX, or Dolby Digital Matrix 6.1.)

DTS-ES Discrete 6.1

DTS-ES uses its large bandwidth to provide a fully discrete rear center channel, as opposed to a matrixed one.
