Okay thats good to know, but I am at this point more interested to know how exactly the `resonant frequency` of the coil is affecting the frequency response of the microphone...
"FvM" said that the low frequencies are lost because the resonant frequency of the coil is damped.... I want to...
i would like to get more deep in the subject, in the net i find no information about that related to microphones.... but to speakers... how much can i relate the theories of impedance and frequency response from a speaker compared to a mocing coil microphone???
this website has a lot of info on...
... the graph is from a "sm57", this mic has an output impedance of 310 ohms... and its a moving-coil dynamic microphone...
yes.... 1:1 means equal output to input impedance
i guess i understand the part of the high frequencies loss due to the inductor (moving coil) ....
but ...
1 - could...
Hey, in this graph im attaching here is showing that if one do a 1 to 1 input impedance to output impedance of a dynamic microphone and an mic pre amp the low and high frequency response of the mic is reduced but the middle frequencies stay intact....
I would like to understand why JUST low and...
im writing a school essay and i made the following statement.... but im not sure if this is correct to say...
"...imagine a non-realistic situation where we could hear the signal straight out of a microphone even before amplification or anything. Placing this microphone right in front of a...
alright, that is definitely a plus on my understanding... tx!
so in this case the input resistance together with the coupling capacitor will work as a first order RC filter??
is the input resistance just equal in value as the grid resistor OR is the input resistance infact caused by the grid...
yeah? ... good to know!
that already changes my perpective of the whole thing again...
i not even know what to ask anymore, i still cant grab the topic properly... is there any book that explains this whole amp thing better?
so by that you mean that depending on the circuit build up from the amp a tube amp can have more capacitve impedance and in other cases more resistive impedance???
is "tube capacitance" related to the capacitor that smooths the alternation in voltage of the tube?
hey, i ve been reading on the topic in some forums in the internet... i found some contradictions on what i read... so i want to clarify that...
so in one forum i read that tube amp input impedance is mostly a capacitive impedance that stays on the picofarad range (very small)....
in other...
hey... Ive read a bunch of articles in the internet about impedance... im wrting at the moment a simple essay and i put some words together to define input and output impedance... but im still not 100% sure of what exactly they are.... ive read this in wikipedia which confused me a bit:
"The...
hi... otherday i was goin to play keyboard and notice that the power suppy had its cable broken... so i looked for a new supply at home... i connect it to the keyboard and the thing worked totaly fine...
but just out of curisity...
the original supply is 12v with 2 A
the new suppy though is of...
ok,
the point of my question is more like.... sound waves come in the air hit the microphones membrane... then the coil moves, creates changes on the electric field thats happening inside the moving coil system...
then the sound frequency will have an equivalent electrical frequency in the...
alright... thats very good info.... i never heard before from the low and high resonance frequencies... thats an important point i was missing....
tx!!!
is any book where i can get to know more in details this thema???
but what about the frequency from an AC circuit and audio frequency, whats...
Hi,
I`m doing at the moment an essay about how impedance affects the frequency response of dynamic microphones...
like, if a preamp has high or low input impedances it will change the way the microphone captures the audio frequencies....
I`m going through all the basics of electronics.... and...
okay... it was totaly it!!!
i tried the pedal just with battery and no hum is to be heard...
i also found that the battery cable was touching the power supply cable.
i fixed it and tried just at home with a new supply... and seems its all good... any of this days i will try it loud at the...
