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
