The Shure MX690 Microflex Wireless Boundary Microphone offers total freedom of placement with no holes to drill or cables to run for installation. The MX690 plate mic is a both a microphone and a wireless transmitter and is the perfect solution for conference and meeting spaces where users demand flexibility and high performance. Compatible with Shure SLX wireless systems, including the SLX4L receiver with logic output for applications requiring logic functionality.
Consumer Alert:Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
