ELECTRET CONDENSER BOUNDARY
MICROPHONE
Description
The ASTATIC 901R is a superior low noise, electret condenser
cardioid surface mounted boundary microphone. It has been
redesigned with improved RF immunity to greatly reduce
susceptibility to radio interference from GSM based cell
phones, PDA/cell phones with walkie-talkie capability and
other similar devices. It is ideal for use on altars, conference
tables, stage floors, or television productions.
The 901R's electronics features an advanced transformerless
design and is self-contained to eliminate the need for mounting
any external boxes. The cardioid pickup pattern minimizes
annoying feedback when used close to sound reinforcement
speakers and monitors, while reducing the pickup of unwanted
off axis sounds. The integral 80Hz, 12dB/oct hi-pass filter
removes unwanted low frequency energy. .
The die cast zinc base and double layer perforated steel screen
construction makes this microphone extremely rugged. The
901R can also be permanently mounted on most flat surfaces
with the supplied wood screws. The 901R comes with 30
feet of high quality microphone cable that has a miniature 3
pin connector on the microphone end and a standard
professional XLR type connector on the opposite end. The
901R will operate with any equipment that supplies standard
P12, P24 and P48 volt phantom power.
