MODEL A15HP HIGH PASS FILTER
This filter rolls off low audio frequencies to reduce 60 Hz 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).
