CAD Audio 202RW Mini Omnidirectional Boundary Button Microphone
The ASTATIC 202RW microphones are miniature, high performance electret condenser microphones designed for low profile mounting in panels, tables, or ceilings. They have been redesigned with improved RF immunity to greatly reduce susceptibility to radio interference from GSM based cell phones, PDA/cell phones, cell phones with walkie-talkie capability and other similar devices. They are excellent choices for teleconferencing, voice-lift, professional recording, courtrooms, sureveillance and many other critical applications. The
201R and 202R are 1.1" in diameter at the largest point and mount in a 13/16" opening in panels up to 2" thick. The 202RW are extremely rugged and feature a solid machined brass body and Astatic Flex-Form™ hardened grille screens. The 202RW also have a built in 80Hz, 12dB/oct high pass filter and are terminated with a standard male 3-pin XLR connector. Color matched shockmount isolators are also included with each microphone. (15/16" mounting hole required when using shock isolators).
Features:
Teleconferencing or voice lift sound reinforcement in meeting spaces
Surveillance and ambient recording or audio observation
