Solderless High Impedance Audio Amplifier Kit 1
https://www.mikeselectronicparts.com/product/audio-amplifier-kit-1/
The amplifier should work well with other home built radios but was not designed as a general purpose amplifier for mp3 players, phones and the like. The kit was designed for use with a high impedance headphone or earphone with 2,000 ohm …
High Input Impedance and Low Output Impedance in Op …

2. What is high input impedance amplifier? A high impedance input places very little load on a signal that is applied to it. It thus does not reduce it in level (or not much). A unity gain buffer usually has very high impedance and is …

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.
What is Impedance in Audio? Input and Output …

For instance, if you connect a microphone to a mixer, your microphone has an impedance of less than 200 Ohms. 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.
Why is it desirable in an amplifier to have high input ...

Actually, the premise of your question is only true if the signals you are interested in are voltages. In that case, if the amplifier draws no current through its input (has infinite, or at least very high input impedance), then connecting it to a source won't affect the signal voltage, regardless of what the source impedance is. Similarly, when you connect a load to the output of your …
What Is The Input Impedance Of A Common Emitter Amplifier ...
https://larryweltman.com/what-is-the-input-impedance-of-a-common-emitter-amplifier/
The answer is the high input impedance is good for the amplifier circuit to have a good amplification of the input signal other wise we get low voltage in, so low amplification. I hope this can help, thank you.

Not only that we see small High impedance preamplifier. Try tiny amplifier circuit. This is a high impedance small amplifier circuit. It can give power output about 1W with connecting to a 9V power supply. The advantage of this circuit is using dual Darlington transistors. So they have more size of input impedance about 20 Mega ohms.
Amplifier Input Impedance - High-End Audio Discussion Forum

You can have a high input impedance on a solid state amp by using FET devices at the input. Large solid state amps with a low input impedance often do have a lot of gain as they are designed for use with loudspeakers that need a lot of power. You need gain for that- 30 db might barely be enough.

Since the pick-up presents a relatively high output impedance, it is normal to provide guitar preamp and DI inputs with a hugely high input impedance. A minimum value is typically 470kΩ, but many are over 1MΩ and a few, designed for accepting feeds from magnetic pickups in some acoustic guitars, are rated even higher than this.
