Description

General Description

Use this balanced-line attenuator to prevent low-impedance microphones (rated at 150 or 600 ) and high-output condenser microphones from overloading low impedance inputs in high sound pressure level applications. The values of attenuation can be switch-selected for 15, 20, or 25 dB.

Use the A15AS with any low-impedance microphone, including phantom-powered condenser microphones, such as the Shure SM81. It can be used in-line between the microphone and its power supply. (This model is not suitable for use with the condenser powering system called “A-B Powering.”)

The A15AS attenuator bridges the microphone output and allows maximum signal handling with a minimum of loadingcaused distortion or reduction in clipping level.
