如果有人买一套新的音响系统,从不同的厂家挑选了一个立体声接收器、一个功率放大器、一个CD机、一个磁带机和一套喇叭,把它们搬回家,赶忙装配这些组件,好欣赏几张刚买的CD唱片,然而却发现CD机因为有特殊的连线而不能适配功率放大器;尽管立体声接收器可以工作,但不知什么原因,却不能将它复制到磁带上去。值得庆幸的是:这种情况不常发生。消费电子工业在很久以前已经建立了音响设备连接的标准。这样,一个厂家生产的设备可以和其他厂家生产的设备相兼容。因此,装配一些相对独立的音响组件还是很容易的。
If someone buys a new audio system, picks up a stereo receiver, a power amplifier, a CD player, a tape drive, and a set of speakers from various manufacturers and moves them home and quickly assemble the components for enjoyment However, we found that the CD player can not adapt to the PA because of the special connection. Although the stereo receiver can work, it can not be copied to the tape for some reason. Fortunately, this is not the case. The consumer electronics industry has long established a standard for audio device connectivity. In this way, the equipment produced by one manufacturer can be compatible with the equipment produced by other manufacturers. Therefore, the assembly of some relatively independent audio components is still very easy.
