What does the Impedance knob on a pre-amp do ?
The preamps control aluminum knob input impedance is essentially the electrical resistance that the mic "sees" when connected to it. In order to explain what effect input resistance has we need to look at some standard electric theory.
When you link a mic to a preamp control aluminum knob you are basically producing what is called a voltage divider. The microphone is a voltage source, as the diaphragm generates a voltage. The preamp control aluminum knob is serving as a "load" on that particular source.
What occurs when you connect the two is that the voltage from the mic is split in between the mic as well as the preamp control aluminum knob. Preferably we want as much voltage throughout the preamp as feasible, as this translates into a greater signal degree.
Voltage will develop across resistance (impedance). If the mics outcome impedance is equal to the preamps input resistance, the voltage obtains split 50/50, which isn't so great. As we boost the input resistance of the preamp control aluminum knob it causes proportionally more of the voltage to create there, which is what we want. Nonetheless a better input impedance generally equates to more sound, so it's a trade off.
Normally the provided general rule is that your preamp control aluminum knob input insusceptibility intends to be 10x your mic output resistance. The Neumann 102 has a result resistance of 50 ohms from what I can see, so your pre requirements to be able to show the mic a 500 ohm input resistance (which is really fairly low in the system of things).
Utilizing this rule will certainly make sure that the mic generally talking will show a flatter reaction, often with added information in the high frequency array. Lowering the input insusceptibility can lead to a dulling of the mic, and also this is the main factor that individuals play around with variable resistance.
