This high pass filter rolls off low audio frequencies to reduce 60Hz electrical hum, low-frequency wind noise, air conditioner noise, or stand- and floor-transmitted low-frequency vibrations. When loaded with a low-impedance microphone input (800 ohms or more), the rolloff is 12 dB per octave below 100 Hz. When loaded with 150 ohms, the rolloff is 3 dB at 100 Hz. The output is flat above the rolloff point (with a maximum loss of 0.5 dB at 1 kHz).
Frequency Response:
Flat above rolloff point; –0.5 dB maximum at 1 kHz
Impedance:
Designed for 150 ohm rated microphones and inputs
Distortion:
2.5% maximum (100 mV input, open circuit output)
Overall Length:

Case:
Full magnetic shield, steel with gray enamel finish
Dimensions:
19 mm (3/4 in.) diameter; 114 mm (4 1/2 in.) long
