Today’sadvanced sound reproduction technology lets you getextremely close to the sound of a live performance, butchances are you’ll still notice something missing: theacoustic environment of the live concert hall. Extensiveresearch into the exact nature of the sonic reflectionsthat create the ambience of a large hall has made itpossible for Yamaha engineers to bring you this samesound in your own listening room, so you’ll feel all thesound of a live concert.Furthermore, our technicians, armed with sophisticatedmeasuring equipment, have even made it possible tocapture the acoustics of a variety of venues such as anactual concert hall and theater to allow you to accuratelyrecreate one of several actual live performanceenvironments, all in your own home.Dolby Pro Logic SurroundThis unit employs a Dolby Pro Logic Surround decodersimilar to professional Dolby Stereo decoders used inmany movie theaters. By using the Dolby Pro LogicSurround decoder, you can experience the dramaticrealism and impact of Dolby Surround movie theatersound in your own home. Dolby Pro Logic employs afour-channel five-speaker system. The Pro LogicSurround system divides the input signal into four levels:the left and right main channels, the center channel(used for dialog), and the rear surround sound channels(used for sound effects, background noise, and otherambient noises). The center channel allows listenersseated in even less-than-ideal positions to hear thedialog originating from the action on the screen whileexperiencing good stereo imaging.Dolby Surround is encoded on the sound track of pre-recorded video tapes, laser discs, and some TV/cablebroadcasts. When you play a source encoded with DolbySurround on this unit, the Dolby Pro Logic Surrounddecoder decodes the signal and distributes thesurround-sound effects.This Dolby Pro Logic Surround Decoder employs adigital signal processing system. This system improvesthe stability of sound at each channel and minimizescrosstalk between channels, so that positioning ofsounds around the room is more accurate comparedwith conventional analog signal processing systems.In addition, this unit features a built-in automatic inputbalance control. This always assures you the bestperformance without manual adjustment.Manufactured under license from Dolby LaboratoriesLicensing Corporation. “Dolby”, “Pro Logic”, and thedouble-D symbol are trademarks of Dolby LaboratoriesLicensing Corporation.Dolby Pro Logic Surround + DSPDolby Surround sound system shows its full ability in alarge movie theater, because movie sounds areoriginally designed to be reproduced in a large movietheater using many speakers. It is difficult to create asound environment similar to that of a movie theater inyour listening room, because the room size, materials ofinside walls, the number of speakers, and other factorsof your listening room are much different from those of amovie theater.Yamaha DSP technology made it possible to presentyou with nearly the same sound experience as that of alarge movie theater in your listening room bycompensating for lack of presence and dynamics in yourlistening room with its original digital sound fieldscombined with Dolby Surround sound field.The combination of Dolby Pro Logic Surround and DSPis used on the sound field program “ PRO LOGICENHANCED”.The YAMAHA “CINEMA DSP” logo indicates theseprograms are created by the combination of Dolby ProLogic and YAMAHA DSP technology.CINEMA DSP
