具有先进的脉冲数码/模拟转换器和高密度的线性转换器系统日本索尼公司最新推出的数码音响激光唱机系列如,CDP—X707ES、CDP—X505ES、CDP—X202ES、CDP—711、CDP—D7、CDP—411、CDP—311和CDP—211等,都配备了有独特先进的脉冲数码/模拟转换器和先进的高密度线性转换器系统。在数码/模拟转换过程中,引进了脉冲幅长调节(Pulse Length Modulation)技术。传统的转换器系统采用的是16位编码与同样数字的电子开关,进行转换的过程。而该系列机的脉冲转换器则采用了单一的电源和单一的开关,使数码/模拟转换过程变得极为快速。脉冲信号密度高达每秒9千万次,能产生特别精确而细致的信号分解度。而且,先进的
Advanced Pulse Digital-to-Analog Converters and High-Density Linear Converter Systems Sony’s latest digital audio compact disc players such as the CDP-X707ES, CDP-X505ES, CDP-X202ES, CDP-711, CDP-D7, The CDP-411, CDP-311 and CDP-211 are all equipped with unique advanced pulse DACs and advanced high-density linear converter systems. In the digital / analog conversion process, the introduction of pulse amplitude modulation (Pulse Length Modulation) technology. The traditional converter system uses a 16-bit code with the same number of electronic switches, the conversion process. The series of pulse converter uses a single power supply and a single switch, the digital / analog conversion process has become extremely fast. Pulse signal density of up to 90 million times per second, can produce a particularly accurate and detailed signal resolution. And, advanced
