WebSep 12, 2013 · IMHO, an impedance switch would be virtually useless for most condenser microphones. The output buffer amplifier circuits in most designs are insensitive to mic pre input impedance. (Except that lower impedances may reduce signal levels.) Reducing the signal level is generally NOT a good thing because it reduces your signal-to-noise ratio.

To pull high, far less current in the opposite direction is required of the source. An "input impedance" calculated at 2.5k ohms assumes a TTL input is linear - it is not: forget about "2.5k input impedance". Minicircuits suggests that 2mA is required, not 1.6mA. fintech herald linkedin
