如果鼓被越来越有力度的击打，我们经常会希望把麦克内置的衰减开关打开，这样会帮助减少失真的机会。
If the drums will be hit medium to hard, you'll usually want to enable the mic's built-in attenuation (" pad ") switch. This helps minimize the chance of distortion.
应该等待足够的时间，使开关瞬态信号衰减，电流达到稳定，然后再进行测量。
The current should be measured after a sufficient settling time to allow the switching transients to decay and the current to stabilize.
可能就需要一个放大器或衰减器，以确保通过开关传输所需的功率。
An amplifier or attenuator may be needed to ensure that the required level of power is transmitted through the switch.
