关于focusrite isa428MKII怎么用？
请教各位英文好而且用过focusrite isa428的大虾，这个话放上的Z in功能怎么用呢？还有Trim insc旋钮具体是怎么用的呢
TRIM
The trim control provides additional variable gain of 0dB to +20dB when Mic or line inputs are selected. The level lf trim chosen is indicated on the front panel by the inner arc lf numbers around the trim knob. Note: when using the instrument input the trim control is used to adjust gain. the additional 20dB of gain that can be applied to the Mic or line signal is very useful for two reasons:
When high gain is required
The trim used in conjunction with the mic gain of 60dB will give a total of up to 80dB of pre-amp gain, making it very useful for getting good digital recording levels from very low output dynamic and ribbon microphones.
Gain adjustment during recording
When small amounts of gain adjustment are needed to correct for performance level variations during recording, use the trim knob rather than the stepped mic/line gain knob, as switching the 10dBgain steps would be much too intrusive. It is therefore good practice to apply some trim gain before using the 10dB stepped gain knob to find the optimum recording level so that the trim control can be used to gently add or take away gain later, if so required.
严重感谢了！

当选择mic或者线路输入的时候, The trim控制可以提供额外的变化增益0 db到20 db.这种情况下,面板上指示灯就会按trim 的旋钮的数字大小亮起. 注释: 当使用乐器输入连接trim控制来调整增益时,在mic和line输入上，有额外的20db的增益量，这是非常有用的，有两点好处：
1 当需要高的增益时
trim控制和mic的60 db的增益相连接总共提供80 db 的前级放大。这对于数字录音中使用较低铝带式的话筒(动圈话筒的一种)是非常有益处的。
2 录音中需要增益调整
当需要少量的增益调整，录制正确的多变的演奏录音时，使用trim旋钮相当于使用级进的 mic或者line的增益旋钮，10db增益逐步被调整。因此要使用10 db的级进增益旋钮就要掌握最佳的录音。如果有必要，可以少量调节或不使用增益调节。在trim增益调节上，要有更多的实际操作。
