1984年起,以日本为主的国外报刊出现了“AV时代”、“AV机器”等提法。进入90年代,国外的AV放大器开始大规模涌入中国,其中以索尼、天龙、第一音响、飞利浦等势头最劲,现AV也成了继Hi-Fi之后另一发烧潮流。由于它只是近三、四年才开始被人们认识,许多人对它尚缺乏深刻的了解,有必要介绍一下。 AV是英语AUDIO和VIDED的缩写,A代表声频,V代表视频,AV放大器是可用以连接视频设备与声频设备,起中央控制作用的多输入端、多路功放的环绕声合并式放大器,具有大功率输出,并附有智能遥控器。一般除具备各种信号源的处理功能外,还带有调谐器、多段储存式图示均衡器、多功能显示屏等,故AV放大器也称AV中心。 AV放大器的输入端子、除传统的RCA插口、包括数码信号输入外,还有适用于Y/C(亮度信号/色度信号)分离的S端子,用以提高播放画面的质量。有些放大器除4到6路功放(前面两路、中央一路及后面两路)及AV选择器外,还包括A/D
Since 1984, the overseas press mainly in Japan appeared such as “AV Age” and “AV Machine”. Into the 90’s, foreign AV amplifier began a large influx of China, including Sony, Denon, the first sound, Philips and other momentum momentum, now AV has become another fever trend following Hi-Fi. Since it only started to be recognized by people in the last three or four years, many people lacked a deep understanding of it and it is necessary to introduce it. AV is an acronym for English AUDIO and VIDED, A for audio, V for video, an AV amplifier for connecting video and audio devices, a central control multi-input, multi-channel amplifier for surround-sound combined amplifiers, Power output, with intelligent remote control. In addition to generally have a variety of signal processing functions, but also with a tuner, multi-segment storage graphic equalizer, multi-function display, so the AV amplifier also known as the AV center. AV amplifier input terminals, in addition to the traditional RCA jack, including digital signal input, there are for Y / C (luminance signal / chrominance signal) separation of the S terminal, to improve the playback screen quality. Some amplifiers in addition to 4 to 6 amplifier (the first two ways, the central way and the back two) and AV selectors, but also includes A / D
