A15AS -- Switchable In-Line Attenuator
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 attenu
ation can be switch-selected for 15, 20, or 25 dB.
Use the A15AS with any lowimpedance micro
phone, 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 “AB
Powering.”)
The A15AS attenuator bridges the microphone
output and allows maximum signal handling with
a minimum of loadingcaused distortion or reduc
tion in clipping level.
