Shure A15AS Selectable Mic Attenuation

In-Line Pad with 15, 20 or 25 db of Selectable Microphone Attenuation
Shure A15AS Selectable Mic Attenuation


The Shure A15AS Switchable In-Line Attenuator reduces the level of any balanced microphone or line-level signal by 15, 20, or 25 dB.

It is specially suited to reducing the level of a high-output microphone to prevent it from overloading the microphone input of a mixer or recorder in applications with high sound pressure levels.

  • Provides 15dB, 20dB or 25dB of microphone attenuation
  • For use with all low-impedance and phanton-powered condenser microphones
  • XLR input and output
  • Full magnetic shield in a steel, gray enamel finished case

In addition, the A15AS may be used to reduce the level of a line-level mixer output to prevent overloading the aux-level input of a recorder.

The A15AS is equipped with a female 3-pin XLR connector on the input side, and a male 3-pin XLR connector on the output side. Attenuation is controlled by a three-position slide switch.

The A15AS allows phantom power to pass through from the mixer to the microphone, so it can be used with condenser microphones.
