Variable Input Impedance is intended to optimize the MPA Gold for the widest range of microphones.

可变的输入阻抗使得话筒的发音更加的灵活（150欧姆到3000欧姆）。

Looking at the nomograph,we can see the original as 15ohms,using the old equalizer and with the old bass unit which had about a 7ohm resistance.

检视列线图表，我们可以看到旧款的阻抗在15欧姆，它使用了旧的等化器与旧的低音单体，这单体的阻抗大约是7欧姆。

Transferred to loudspeakers this would result in impedances from 4 Ohms to 80 Ohms.

转换成喇叭的阻抗的话，大约相当于4欧姆到80欧姆。

DB and, what is now considered the conventional impedance of 8 Ohms.

*分贝，什么是目前被认为是传统的8欧姆阻抗。

It also has a low impedance, which assures that the typical unbalanced output impedance is between 100 and 1000 ohms.

同时它的低阻抗可以确保典型的非平衡输出阻抗保持在100到1，000欧姆之间。

The equivalent circuit model was used to simulate the EIS to investigate the effects of temperature and air volume flow rate on the cell's performance,mass transfer and Ohmic resistance.
