They have continued the evolution of home theater with the introduction of Dolby DigitalPro-Logic, a Multi-Channel Digital delivery system. Just as Dolby Surround found its beginnings in the cinema, so does DolbyDigital. This advanced multi-channel digital sound, although originally conceived for and later chosen for HDTV, made it prec-tical to implement in the cinema because it enabled the film to retain the analog soundtrack. With backwards compatibility apriority so the film could be played in any cinema, it was decided to place the new digital optical track between the sprocketholes, which was a key factor in defining its maximum practical bit rate (see illustration).In 1992 Dolby Surround Digital, the film sound format with Dolby Digital as its keystone, made its debut in the cinema. In lessthan three years, more than 300 feature films had been released in this new format, and nearly 1,500 cinemas had beenequipped for playback of the digital soundtrack. Furthermore, Dolby Digital can now be brought to the consumers home todayvia the LaserDisc.Traditional Pulse Code Modulation (PCM), which is utilized on compact discs and LDs 4-channel matrixed digital audiotracks, uses a 16-bit word to “describe” the sampled point in the original analog wave. By sampling this analog wave 44,100times per second for each channel, the system will yield a dynamic range of 96 dB from the loudest sound to the noise floor.However, this process creates an immense amount of data which is too large for multi-channel systems. Thus, a form of datareduction must be employed to reduce the total amount of information without serious degradation of the sound quality hence the introduction of Dolby Digital.The premise of Dolby Digital is simple, it reproduces the full bit resolution (16-bit) when a lower resolution will not result in thesame sound quality. However, when a lower resolution is acceptable, it will utilize this lower resolution opting instead for psy-choacoustical theories and digital noise filtering technologies to help insure acceptable sound quality.4Channel AnalogSoundtrack (Matrixed)AC-3ENCODINGAC-3 IN THE CINEMA5.1 ChannelDigital SoundtrackRadioFans.CN 收音机爱 好者资料库AMPLIFIEROUTPUT POWERRZ-5700AV/RZ-7700AVSTEREO (6OHM, 0.09%, 1KHz)130W + 130W5CH (6OHM, 0.3%, 1KHz)FRONT L, R 100W + 100WCENTER 100WREAR L,R100W + 100WOUTPUT POWERRZ-3700AVSTEREO (6OHM, 0.09%, 1KHz)70W + 70W5CH (6OHM, 0.3%, 1KHz)FRONT L, R 50W + 50WCENTER 50WREAR L,R50W + 50WS/N RATIO(INPUT SHORT, IHF A FILTER) 90dB(RZ3700AV/RZ5700AV),95dB(RZ7700AV)SEPARATION(INPUT SHORT, 1KHz) 72dBMINIMUM NOISE 0.3mVCROSSTALK(1KHz) 73dBTUNERFMUSABLE SENSITIVITY(DISTORTION 3%) 2dBuIMAGE REJECTION RATIO 80dBS/N MONO80dBS/N STEREO70dBSEPARATION40dBTOTAL HARMONIC DISTORTION (MONO)0.30%AMUSABLE SENSITIVITY51dBS/N RATIO 50dBTOTAL HARMONIC DISTORTION 0.6%VIDEO SectionInput sensitivity and impedance1.0 V P-P/75 ohmsOutput level and impedance1.0 V P-P/75 ohmsSURROUND SectionDelay timeRZ-3700AV/RZ-5700AVDOLBY SURROUND 1530mSTHEATER SURROUND550mSHALL, DOME, NATURAL SURROUND5100mSDelay timeRZ-7700AVDOLBY PRO LOGIC REAR SPEAKER1530mSDOLBY DIGITALCENTER SPEAKER05mSREAR SPEAKER015mSOthersPower requirements.230V, 50/60 HzFor Taiwan120V (60 Hz)For Europe230V, 50 HzPower consumption390 watts 490 VA560 watts Maximum / 1,300 watts Maximum(RZ-7700AV)Dimensions420 mm (1615/16) W130 mm (511/16) H343 mm (1313/16) DWeight14 kg (RZ-3700AV),15 kg (RZ-5700AV),13.5 kg (RZ-7700AV)1.
