经过几年的市场熏陶和发展,由于数码影音科技日新月异,自1999年《星战前传》首次推出的 Dolby Digital Surround EX 6.1概念音效以来,6.1声道技术已经脱下尊贵的外衣,摘下原来只有高档器材才可以引以为傲地享用的顶尖技术的光环,开始变成普及型 AV 放大器的标准配置,而且6.1声道的技术也不断扩展,延伸到普通的2声道立体声也可以处理成6.1声道音效。在电影DVD 碟片的发行中,也越来越多的发行商引入了6.1声道音轨,像热卖的《魔戒》系列 DVD 就是其中的佼佼者。对于要升级原有的5.1声遒系统或者全新组建家庭影院的朋友而言,能够支持6.1声道解码和一些更新的数字音频格式已经成为基本的需求,而在整套器材当中,AV 放大器无疑是其中的核心所在,承担了各种音频解码和多声道放大的工作,同时在现代视听系统中还是理所当然的信号切换和管理中心,重要程度不容
After several years of market influence and development, due to the ever-changing digital video technology, the 6.1 channel technology has taken off the noble coat since the first introduction of the Dolby Digital Surround EX 6.1 concept soundtrack by Star Wars in 1999, The only aura of top technology that only high-end devices can take pride of place is standard equipment for universal AV amplifiers, as well as 6.1-channel technology that extends to common 2-channel stereo processing 6.1 channel sound. In the movie DVD disc distribution, more and more publishers have introduced 6.1-channel audio tracks, such as the hot “Lord of the Rings” DVD series is one of the best. For those who want to upgrade their old 5.1 sound system or build a new home theater, the ability to support 6.1-channel decoding and some newer digital audio formats has become a basic requirement, and AV equipment is undoubtedly among the complete set of equipment The core of the commitment to a variety of audio decoding and multi-channel amplification work, while in the modern audio-visual system is still a matter of course the signal switching and management center, the degree of importance can not
