PRA-528B/C series are stationary gooseneck microphones for conferences;
they feature a back-electret condenser construction. Their tailored
frequency response, excellent cardioid polar pattern and high gain before
feedback make them the ideal candidates for conference.
There are two members in this series: PRA528B is a plug-in microphone for
quick installation, while PRA528C is a short-based microphone with a
separated preamplifier. Each mode has a section of adjustable gooseneck,
which makes it convenient to change the direction. There are two lengths
and various installing modes to accommodate the demands of different
applications.

Extended frequency response and wide dynamic range to pick up vocals
exactly and clearly.
Balanced output to ensure the signal transference free of noise in long
cable.
Two gooseneck lengths and two installation modes for different
applications.
PRA528 are tested with 2000 noiseless bending cycles to ensure
durability.
Comes with standard base and pop screen for easy installation and up-
close speech.
