What Is High Impedance? 

Is this why some pedals don't play nicely in some amplifiers effects loops? 🇦🇺

@sweetwater you lost me at no visual representation please use graphics.

you can slow down the video reading speed at 0.75 and it's quite audible

Ha

lol

Lol 😅

This def would have benefitted from *any* sort of visual aid. Too much info and too fast for the people most likely to benefit from this kind of conversation. This assumes a LOT of prior knowledge.

I still don’t really get it. Visual aid might help.

😂

Exactly. High impedance headphones may need an amp to get loud.

Hi MajorSeventh. Here's our video specifically about headphone impedance: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0Ki_-reu4PE.html

Don't get me wrong, I know it. But with the way he read it so fast off the teleprompter, you must have known it well to be able to follow him.

Hi, thanks for your interest! “Loading down” in this context means connecting a source of electricity (or audio) to an input whose impedance is too low. Mitch used the example of a wall outlet with too many appliances connected to it, but another audio example would be running too many passive speakers off a single output on a power amp - each added speaker reduces the impedance and potentially “loads down” the signal. Here’s another resource for more info: www.whirlwindusa.com/tech-articles/high-and-low-impedance-signals Hope this helps - feel free to contact me directly with any further questions, and thanks again!

I'm gonna try watch this again in half speed! But this current vs voltage thing... ... ...

@@thesebdav8602 Funny! Me too!

Water. Replace electricity with water and it's easier to understand because you have direct experience with it. Imagine you have a 1 gallon bottle of water, and you empty it through a drinking straw. It's going to empty in a couple of minutes. Now picture it emptying through a garden hose. It will empty much faster, in 10 - 15 seconds. The hose lets more water pass through, so it has a higher current. Current is how much water is passing out of the jar each second. In electricity, current is the amount of electricity passing through your circuit. It's called amperage and is measured in amps. Now why is the water emptying? Gravity. So the weight of the water in the jar is pushing the water out. With either the straw or the hose, the water in the jar is pushing the water the same amount. If this was electricity, the "weight", or the pressure pushing the electricity through the wire is called voltage. So current is the amount of electricity passing through the circuit, and voltage is the pressure pushing that current. The straw is much smaller than the hose, so only so much water can pass through it. So the small size of the straw is resisting the water's effort to pass through it. The larger hose provides less resistance to the flow. So resistance is a measurement of how hard it will be for the water(electricity) to flow through your straw(circuit). Resistance in electricity is measured by ohms and is also called impedance (a higher resistance impedes the flow of electricity). So with the same weight(voltage), if you decrease the resistance by using a larger hose(circuit path), you will get more current. we know the gallon jar will empty quickly either way, so if we set it up such that a certain amount of water is coming into the jar to refill it as it empties, we have a never-ending supply of water, so we can keep the weight of the water constant. This now represents your power source - a never ending supply of electricity. But if the hose lets the water out faster than the jar is being refilled, the weight of the water will drop, and so it will push the water out with less force. So if your circuit has a too low resistance, it will allow electricity to flow through the circuit at a higher rate than your power source can provide, causing a drop in voltage in the circuit, which means the circuit will not perform well because it depends on a certain minimum voltage. Hope that helps.

@@kilroy2517 Thanks, and the water analogy is helpful.

@@kilroy2517 ...., causing a drop in voltage)... can you say off the top of your head what is typically used to "regulate"/ not cause the electrictity to flow so freely throught ac circuit.? is it a transistor? or something else, thank you, hope my quesiton makes sense....
