The Shure Automatic Microphone System consists of the
AMS8000 [or AMS4000J Mixer used with Shure AMS
Microphones. This system's excellent performance, versatility, and ease of use make it an ideal choice for multiplemicrophone public-address and recording systems such as
used in conference rooms, legislatures, churches, courtrooms, broadcast studios, teleconferences, and panel
discussions.
The Shure Automatic Microphone System solves many
problems associated with multiple-microphone installations,
such as
because of feedback [howling), and operator errors.
this by turning on only those microphones in use, thus keeping the number of "on" microphones to a minimum. When a
person speaks in front of his microphone [within
side of the front), the microphone turns on. Sounds origina-

ting at the sides or rear of the microphone will not turn it on.
In addition, the system automatically reduces its volume as
the number of "on" microphones increases, thereby
preventing feedback.
The Shure AMS also solves problems encountered with
other automatic mixers such as complicated setup adjustments, unreliable turn-an, and choppy sound. The microphones turn on smoothly and dependably, free of pops or
clicks, and virtually independent of talker loudness or
distance.
You'll find the Shure Automatic Microphone System simple
to install and operate, requiring little more adjustment than
an ordinary PA system. However, the system can also perform a variety of sophisticated functions. Model
has eight microphone inputs; Model AMS4000 has four
microphone inputs.
IMPORTANT
Shure AMS4000 and AMS8000 Mixers are designed for use only with Shure AMS Condenser Microphones. Conventional condenser or other microphones will not operate properly with the
AMS4000 and AMS8000.
