• Microphone amplifier 

• flat frequency response 

• very low harmonic distortion and noise 

• works with 12V and 48V phantom power 

• balanced, low-impedance output 

• high suppression of interference on the microphone cable 

• excellent protection against high-frequency radio interference with "RFI Shield" 

• frequency-independent impedance 

• signal transmission possible over very long cables 

• reliable operation even with weak phantom power 

• symmetrical, transformer- and capacitor-free output stage with a class-A amplifier 

• above 20 kHz, the signal is attenuated for protection against interference in the ultrasonic range, e.g. through the ultrasonic autofocus of a film camera
