開關器材很多人都懂
只要知道開關的按鈕在哪就可以
但開關的次序卻不是人人都知道的
當然開關次序不對是不會造成爆炸的
但如果長期次序錯
會令某些器材的零件受損
器材自然容易損壞
第一樣需要開的是
電源
由於所有器材需要的都是電
所以這個是最簡單卻最易被忽視的
例如電插頭有沒有插
延伸電線(extension cord)有沒有開等等
第二樣要開的是Mixer及所有詢號處理器材(signal processors)
例如無線mic接收器/EQ/Crossover/等等
另外在用Mixer時
最好把所有的頻道(channel)都無聲(muted)
這樣就不會被台上的詢號影響
如果台上有人用結他或唱歌等都不會有影響
最後是擴音器及音箱
這兩樣必需留到最後
是因為避免在其他器材開關時會造出很大"Pop"的聲響
會令音箱受損
其實這些都是很簡單的小次序
我個人都是做錯過好幾次在慢慢記住的
只要習慣了就慢慢會做對的了
Nice advice! I just have two comments/addendum:
ReplyDelete- You've already mentioned the power-up sequence. The power-down sequence should simply be the reverse of the power-up sequence.
- It is possible to make the powering sequence easier, reducing the whole sequence to a simple on/off switch by the use of a "power sequencer." Once properly configured, the power sequencer can do the proper power-up (and -down) sequence for you, with an optional time delay between steps.
Yea I can't think of a reason not to use power sequencer! It really saves time to turn equipments on and off. It will be definitely useful especially with large scale AV system and touring.
ReplyDeleteThanks for add-on!!!
