Switchable in-line attenuator

MODEL A15AS SWITCHABLE IN-LINE ATTENUATOR

Use this balanced-line attenuator to prevent low-impedance

microphones (rated at 150 or 600 Ω) 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 pow-

er 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 loading-caused dis-

tortion or reduction in clipping level.
