Shure A15AS Dempeledd for XLR

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. 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. SPECIFICATIONS Frequency Response Flat, 20 to 20,000 Hz +-0.5 dB Impedance Input (XLR Female): 1.000 ohm Output (XLR Male): 150 ohm Attenuation (switch selectable) 15 dB, 20 dB, or 25 dB Case Full magnetic shield; steel with gray enamel finish Dimensions 19 mm (3/4 in.) diameter; 114 mm (4 1/2 in.) long NOTE: The equivalent single series simplex-powering resistance is 215 ohm; this resistance should be considered in addition to any existing circuit resistance when using the attenuator.
