ana Posted April 7, 2006 Author Report Share Posted April 7, 2006 1. What’s meaning of this word?- Stray pickup-Dc biasing levels2. I’m simply done a mic preamp, mixer and power amplifier. So, what’s the function of my mixer? Is just combining from various inputs to mono/stereo output, right? No other special in this circuit if I do like that, ????

audioguru Posted April 8, 2006 Report Share Posted April 8, 2006 1. What’s meaning of this word?- Stray pickupCrosstalk from another input, interference, mains hum or other "stray pickup".-Dc biasing levelsAudio amplifier stages are usually biased so that their output can swing equally positive and negative from the DC biasing level that it has without input for max undistorted output level. 2. I’m simply done a mic preamp, mixer and power amplifier. So, what’s the function of my mixer? Is just combining from various inputs to mono/stereo output, right? No other special in this circuit if I do like that, ????An audio mixer is used to adjust the balance of levels between musical instruments and singers.

ana Posted April 8, 2006 Author Report Share Posted April 8, 2006 again...forgot to ask..what d difference between mixer that I've done with a mixer involve a local oscillator n so on? Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 8, 2006 Report Share Posted April 8, 2006 what d difference between mixer that I've done with a mixer involve a local oscillator n so on?Your audio mixer adds signals together without making new frequencies.A radio's mixer multiplies the input RF signal and the local oscillator which makes new sum and difference signal frequencies.

ana Posted May 6, 2006 Author Report Share Posted May 6, 2006 hellooo.......I 've a problem bout the description in my circuit-microphone preamplifierwhy a certain mic preamp circuit needs a LED?how about if this LED is ignored?isn't affected its function of my circuit?then, i want to know about a repeater..isn't repeater concept is used in audio mixer?and what the function it suppose to?isn't repeater very important?Before this you have says about Fuzz circuit. what its means? (related to distortion)thank you sir :) Quote Link to comment Share on other sites More sharing options...

Please attach its schematic again.i want to know about a repeater..isn't repeater concept is used in audio mixer?and what the function it suppose to?isn't repeater very important?I don't know what is an audio repeater. Please describe exactly what you want it to do.Before this you have says about Fuzz circuit. what its means? (related to distortion)A fuzz circuit adds severe distortion to a guitar preamp. Then the guitar makes a buzzing sound instead of a smooth and clear sound.thank you sir :) Quote Link to comment Share on other sites More sharing options...
