In my electronics II project, I want to build an audio amplifier circuit with tone control and a two line mixer, one is a line in input (CD player, computer...) the other line of the mixer is fed by an electret microphone... Maybe my idea is not clarified (and sorry for my bad composition and English), but the pictures should clarify it....
I hope you answer me quickly since it's late here and I will go buy the components tomorrow.
First, how much output voltage does a powered electret mic. give directly (without a preamplifier)?? ranging in millivolts, I mean 1-100mV??
Second, can I simply connect the electret mic. to one of the inputs of the sound mixer(see the attached circuits) or a have to build a preamplifier for the mic.??
Finally, does it work if I connect the three-channel tone control to the output of the sound mixer/amplifier????
