Description
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
2000 Hz
separated preamplifier. Each mode has a section of adjustable gooseneck,
4000 Hz
8000 Hz
which makes it convenient to change the direction. There are two lengths
PRA528 SERIES
and various installing modes to accommodate the demands of different
applications.
