The Shure A15AS In-Line Switchable Attenuator is an essential tool for any audio professional who demands precision and flexibility. This versatile device reduces the level of any balanced microphone or line-level signal by a selectable 15, 20, or 25 dB, making it ideal for high-output microphones that risk overloading the microphone input of a mixer or recorder. Whether you are dealing with high sound pressure levels in concert settings or need to attenuate a line-level mixer output to avoid overloading your recorder's aux-level input, the Shure A15AS delivers reliable performance.Equipped with a female 3-pin XLR connector on its input side and a male 3-pin XLR connector on its output side, this in-line attenuator is incredibly easy to integrate into your existing setup. The three-position slide switch allows for quick and easy attenuation level adjustments, ensuring that your audio signal is always under control. Moreover, the A15AS is designed to pass phantom power through from your mixer to your microphone, making it compatible with condenser microphones—a feature highly valued by sound engineers and recording professionals alike.
