ShureA15AS Switchable Attenuator

The Shure A15AS switchable in-line attenuator reduces the level of any balanced microphone or line-level signal by 15, 20 or 25 dB. The attenuator is specially designed for reducing the level of a high-output microphone to prevent it from overloading the input of a mixer or recorder in applications with high sound pressure levels. 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 as well.
