Microphone Preamplifier

This is a good pre-amplifier for microphones that can be. Used in, for example, mixing consoles The circuit operates with a dual op-amp type NE 5532. The amplifier must be adjusted. Simply plug the power and control over P1 such that half the supply voltage (6 V) on pin 3 of IC1 state. P2 is then adjusted to the desired volume. R1 = 8,2 kWR2, R4, R5, R6 = 10 kWR3 = 1 kP1 = 4.7 K?P2 = 100 kC1, C2, C4, C6 = 10 uFC3 = 470 nFC5 = 100 nFIC1 NE = 5532
