This is the circuit diagram of mic condenser amplifier. The low-cost and compact mic condenser audio amplifier described right here is deliver good-quality audio of 0.5 watts at 4.5 volts. It could possibly be applied as a part of low-power transmitters, packet radio receivers, intercoms and walkie-talkies.
This is a simple and low cost Tube Head Vacuum Tube pre-amp circuit designed bu PAiA electronics: Vcc – Pin 1 IC1 +12v – Pin 8 IC2, IC3, IC4 -12v – Pin 4 IC2, IC3, IC4 Ground – Pin 8 IC1 IC1 – 4049 CMOS Hex Inverting Buffer IC2, 3, 4 – 5532 Dual Low-Noise OpAmp D1, 2 – 1N4001 D3, 4, 5, 6, 7 – 1N4148 All 1uf caps [...]
Here the simple audio mic pre amplifier circuit based on single IC LM358. The circuit is very simple, inexpensive and easy to built. Component Parts List: R1, R3, R4 = 10K R2 = 1K R5 = 100K-1M Potensiometer C1 = 0.1uF C2 = 4.7uF/16V IC1 = LM358 dual op-amp single supply Mic = Electret Microphone
Designed by Don Tillman, this guitar pre-amp circuit design is dedicated for people who don’t like op-amps. This circuit is a discrete JFET pre-amp design, use 2N5457 as the main component. It has low noise, low distortion, low feedback, overloads gracefully, is small, etc.
