DESCRIPTION
The PAA™ 250 is a cardioid unidirec-
tional dynamic microphone designed
for applications in which a built-in “on-
off" switch is desired. With a clean,
natural speech response and good
noise and feedback rejection, the
PAA 250 is an ideal microphone for
church and institutional systems,
meeting rooms, auditoriums — almost
anywhere in which convenient local
control of the microphone is required.
An integral acoustic foam pop and
wind filter provides effective control of
plosive sounds and moderate wind.
The internal shock-mounting system
minimizes handling and stand noise.
The PAA 250 is a rugged, reliable
microphone well suited for rental
systems, convention centers and
similar rough usage applications.

NOTE
The switch mutes the microphone by
directly shorting across the dynamic
element. Microphones with this type of
switching should not be usec if more
than one microphone is connected to
the same input, since the “off” func-
tion on one microphone will aiso short
any other unit connected to that input.
if this type of operation is required,
the use of a transformer-type
microphone combiner is suggested.
(Another possible alternative is to
rewire the PAA™ 250 so that the
switch :s used to open one side of the
line for ‘off. ”)
