Shure a15HP - Manual
This user manual covers the Shure Model A15HP microphone, focusing on its design principles and key technical attributes. The document highlights how the high-pass filter reduces unwanted low-frequency noise–such as 60 Hz hum or vibrations–while maintaining clarity above its roll-off frequency. It also outlines performance specifications tied to load impedance (e.g., 800 ohms+ for a 12 dB/octave attenuation, 3 dB at 150 ohms) and physical characteristics like dimensions (19 mm diameter × 114 mm length). While warranty details are included, they are secondary to the core product description.

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).
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
