Miniature Gooseneck: 905R

The Astatic 905R is a line-cardioid, quick-mount, miniature gooseneck condenser microphone designed for speech and vocal pick-up. The line-cardioid polar pattern (LocusTM technology) is engineered to attenuate unwanted sources outside of the +/- 45 degree acceptance angle while effectively "zeroing-in" on the desired speaker. Astatic's LocusTM technology provides a significant improvement over other line-cardioid microphones due to diaphragm size and low-noise electronics. The 905R is appropriate for applications such as boardrooms, courtrooms, house of worship and anywhere a gooseneck microphone with optimal distance pick-up is needed. LocusTM technology allows the installer to use the 905R in place of longer miniature-gooseneck microphones without sacrificing performance. It is the perfect solution for the user who prefers not to be distracted by an obtrusive transducer. The 905R is a commercial-grade microphone featuring an all-metal body. The 8mm steel memory-flex gooseneck and ultra-quiet movement provide for worry-free, life-long microphone operation. Special attention has been taken to design the 905R 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.
