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. ASTATIC Quality All 901R microphones are audio tested and inspected prior to shipment. Our absolute commitment to quality insures that ASTATIC microphones remain the Best Value in today's competitive industry. Operation and Maintenance The 901R is one of the finest boundary microphones available. If the mic body becomes soiled by dirt or residue, it may be cleaned using the following procedure. Remove the top screw and lift off the top screen and remove the foam windscreen. Wash the foam windscreen using a mild detergent, and let dry thoroughly. To clean the mic housing, use a cloth dampened with isopropyl alcohol.
