Overview

RF Resistant Mini-Boundary
Condenser Microphone

Details

Miniature installation button style condenser boundary mics for use in
teleconferencing or voice lift sound reinforcement. Other applications
include surveillance, ambient recording or audio observation. Improved
RF immunity to greatly reduce susceptibility to radio interference from
cell phones, PDA or similar two-way communication devices. Available in
omnidirectional in white (202RW) or cardioid in black (201R). Metal nut/
washer hardware supplied.
