過了十幾年，這台擴大機終於壽終正寢了。也不能說完全不能用，但就是有幾個功能壞掉了。但有鑑於它並不是什麼好到非休不可的機器，所以我也就拿來拆看看裡面了。
首先我先上網找了一點資訊，有關Pioneer VSX 455 Receiver的規格：
Dolby Digital 5.1
The VSX-455 is a Dolby Digital 5.1-ready digital audio receiver. Dolby Digital 5.1-capable receivers can be used to power a high-quality digital listening environment similar to that found in movie theaters. The 5.1 channel audio means that the receiver is capable of five audio channels at one time, designed for left, center, right, left surround and right surround speakers and a sixth low-frequency effects channel.
喔~~~原來這是用來配五聲道的擴大機，不過只是數位的。看來應該算是十分入門的一款。
The VSX-455 receiver is capable of up to 110 watts per each speaker channel. The receiver includes pre-output speaker channels for five surround sound speakers, including a center speaker channel. There is also a pre-output speaker channel dedicated for the connection of a subwoofer speaker.
嗯嗯，銘版上也的確是寫總共250W的輸出。
The VSX-455 receiver features a number of inputs for connecting both audio and video input devices. These can be used to connect things like additional CD, Tape, Blu-Ray, DVD and other media devices using A/V connectors on the back of the receiver. The VSX-455 has three available audio inputs and two available video inputs.
喔~~~看來可以接的東西真的很多也，連Blu-Ray都有，這可是十幾年前的產品也！
好吧，接下來就是正式地來拆它了！
