The input impedance of the XLR balanced connector of a mixer or preamp is between 1500 – 3000 Ohms. This ensures an excellent current flow between the two devices. Impedance When Connecting Speakers and Amplifiers

Typically, most microphones therefore have an output impedance of 150-200Ω, and most preamplifier inputs offer an input impedance of between 1.5kΩ and 3kΩ — on the limit of the 'ten times higher' rule of thumb I mentioned earlier.

and a preamp input impedance of RL=Ω the signal loss would be dB As long as the microphone has enough signal strength to provide the minimum signal input to the mixer, it can be an advantage to connect a low impedance microphone to a moderately higher impedance input.

Generally the input impedance to an audio amplifier is 'high'. That is, high enough to be driven comfortably by any audio source output. But of course, without a proper specification, you are taking something of a gamble. 10k to 100k is the usual sort of range we find, though some can be less.

Most power amplifiers have input impedances of at least 20kΩ and higher. Our own power amps, for example, have 30kΩ input impedance, high enough to never reduce bass levels of capacitor coupled preamplifiers, even if they are the vintage kind. So yes, matching impedances used to be a thing to worry about.

The usual rule that works fairly well is source impedance (Rs)<<Input impedance (Zin). << can be interpreted as 5times less but 20times is slightly better. With your Zin=100K this indicates a pot value of 5k or 10k. Now that you have a pot value apply the rule a second time for DVD. It's Rs <5k/10 or about 200ohms to 500ohms.
Preamp - amp impedance matching question | Steve …

General rule of thumb is load impedance 10X or more the source impedance, to minimize voltage loss at the load input. A 14 ohm preamp output impedance is extremely low. You should have no problem with pretty much any amp on Earth with that one, you could load that with a 140 ohm input impedance amp and be in the 10X territory, never mind 33 kohms.

The right answer is to go DAC>Sys>Loki>Hafler. The reason is that the Sys has a very high output impedance - up to 5K ohm - while the Loki is much lower, at 75 ohm. The Hafler has a moderately low input impedance, 22K ohm. The ratio of …
MM Phono Input impedance change 47k to 100k ohms
https://forum.audiogon.com/discussions/mm-phono-input-impedance-change-47k-to-100k-ohms
Most phono stages I have ever seen will use a 47K resistor between hot and ground to set the input impedance. Since the grid of the tube or the gate of a transistor have a very high impedance, in the megohm range, 47K will become the dominant value at all audio frequencies. Likewise if you change to 100K.
