TX-DS939AV功放问世于DollyAC-3技术公布之初,其金色的外观,简洁大方的设计,给人一种高贵的感觉。其AC-3解码器采用了摩托罗拉公司生产的56009型和56004型,24bit数字处理芯片,分别用于处理杜比AC-3和THX控制程序。56009是世界上第一块采用24bit设计的AC-3解码芯片,其工作频率为80MHz,最大传输速率为40MIPS,而传统的20bit芯片,工作频率为66MHz,最大传输速率仅为33MIPs。此外,56009比传统的芯片功耗更低,发热也随之大大减少,这对于整机发热量很大的AV功放来说是很有意义的,可以大大地减少芯片的散热设计工作。它与同样为24bit的THX处理芯片56004搭配使用时,能够做到天衣无缝。 安桥TX-DS939功放的最特别之处是附有测定用的麦克风,利用此功能可
TX-DS939AV amplifier came out DollyAC-3 technology was first announced, its golden appearance, simple and elegant design, giving a noble feeling. The AC-3 decoder uses 56009 and 56004-type, 24bit digital processing chips from Motorola, which handle the Dolby AC-3 and THX control programs, respectively. The 56009 is the world’s first AC-3 decoder with a 24-bit design. Its operating frequency is 80 MHz and its maximum transfer rate is 40 MIPS. The traditional 20-bit chip operates at 66 MHz and has a maximum transfer rate of 33 MIPs. In addition, the 56009 consumes less power than conventional chips, reducing heat generation, which is significant for the AV amplifier with large heat generation and greatly reduces the chip’s thermal design effort. It works seamlessly with the same 24-bit THX processor 56004. Onkyo TX-DS939 amplifier is the most special place with a microphone for measurement, the use of this feature can be
