Shure A15HP High-Pass Filter - Your Audio Frequency Solution
• Balanced XLR in-line high pass filter that significantly reduces low frequencies below 100 Hz.
• This filter effectively rolls off low audio frequencies to eliminate 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). This high-quality filter ensures crystal-clear audio for your recordings or live performances.
