We’re talking of course about the carbon microphone amplifier, a piece of telephone technology which made its way into consumer electronics.

Several types of microphones, especially condensor microphones, have a very high impedance which require that the circuitry which operates them be very close to the diaphragm of the microphone. The ...

A mini dc-dc boost converter and filter scheme using a clever arrangement of capacitor and high-beta transistor provides the 48-V phantom power source needed for a condenser microphone ...

The all-in-one Dynamics 4290 accelerometer/microphone and differential amplifier has both constant current operation and DC/AC amplification, automatic calibration and a low pass filter.

Both come with high/low input sensitivity switches, with the True Acoustic 60 equipped with 48-Volt Phantom Power, Line/Mic Input Sensitivity switch for Channel 2. The True Acoustic 30 has a single 10 ...

Professional condenser microphones require a 48-V supply to charge the internal capacitive transducer and power the internal buffer for the high-impedance transducer output. You ...
