RadioFans.CN 收音机爱 好者资料库 DOLBY DIGITAL SURROUND Dolby Laboratories spearheaded home theater with the introduction of Dolby Surround, and then defined it with the follow-up format Dolby Pro-Logic Surround. They have continued the evolution of home theater with the introduction of Dolby Digital Pro-Logic, a Multi-Channel Digital delivery system. Just as Dolby Surround found its beginnings in the cinema, so does Dolby Digital. 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 a priority so the film could be played in any cinema, it was decided to place the new digital optical track between the sprocket holes, 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 less than three years, more than 300 feature films had been released in this new format, and nearly 1,500 cinemas had been equipped for playback of the digital soundtrack. Furthermore, Dolby Digital can now be brought to the consumers home today via the LaserDisc. Traditional Pulse Code Modulation (PCM), which is utilized on compact discs and LDs 4-channel matrixed digital audio tracks, uses a 16-bit word to “describe” the sampled point in the original analog wave. By sampling this analog wave 44,100 times 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 data reduction 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 the same 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 Analog Soundtrack (Matrixed) AC-3 ENCODING AC-3 IN THE CINEMA 5.1 Channel Digital Soundtrack RadioFans.CN 收音机爱 好者资料库 AMPLIFIER OUTPUT POWERRZ-5700AV/RZ-7700AV STEREO (6OHM, 0.09%, 1KHz)130W + 130W 5CH (6OHM, 0.3%, 1KHz) FRONT L, R 100W + 100W CENTER 100W REAR L,R100W + 100W OUTPUT POWERRZ-3700AV STEREO (6OHM, 0.09%, 1KHz)70W + 70W 5CH (6OHM, 0.3%, 1KHz) FRONT L, R 50W + 50W CENTER 50W REAR L,R50W + 50W S/N RATIO(INPUT SHORT, IHF A FILTER) 90dB(RZ3700AV/RZ5700AV),95dB(RZ7700AV) SEPARATION(INPUT SHORT, 1KHz) 72dB MINIMUM NOISE 0.3mV CROSSTALK(1KHz) 73dB TUNER FM USABLE SENSITIVITY(DISTORTION 3%) 2dBu IMAGE REJECTION RATIO 80dB S/N MONO80dB S/N STEREO70dB SEPARATION40dB TOTAL HARMONIC DISTORTION (MONO)0.30% AM USABLE SENSITIVITY51dB S/N RATIO 50dB TOTAL HARMONIC DISTORTION 0.6% VIDEO Section Input sensitivity and impedance1.0 V P-P/75 ohms Output level and impedance1.0 V P-P/75 ohms SURROUND Section Delay timeRZ-3700AV/RZ-5700AV DOLBY SURROUND 1530mS THEATER SURROUND550mS HALL, DOME, NATURAL SURROUND5100mS Delay timeRZ-7700AV DOLBY PRO LOGIC REAR SPEAKER1530mS DOLBY DIGITAL CENTER SPEAKER05mS REAR SPEAKER015mS Others Power requirements.230V, 50/60 Hz For Taiwan120V (60 Hz) For Europe230V, 50 Hz Power consumption390 watts 490 VA 560 watts Maximum / 1,300 watts Maximum(RZ-7700AV) Dimensions420 mm (1615/16) W 130 mm (511/16) H 343 mm (1313/16) D Weight14 kg (RZ-3700AV),15 kg (RZ-5700AV),13.5 kg (RZ-7700AV) 1.
