The great downsides of lavalier wireless systems are thin sound, feedback and high prices. All three pitfalls are addressed and mitigated with the BLX14/CVL system from Shure. This outfit includes the BLX4 half-rack wireless receiver, the BLX1 bodpack transmitter and the CVL lavalier microphone.
The BLX4 is a single channel wireless receiver with microprocessor-controlled internal antenna diversity. The BLX1 transmitter offers up to 14 hours of continuous use with 2 AA batteries and a 300′ transmission radius. The CVL is a clip-on lavalier condenser microphone in a discreet, miniature form factor, ideal for professional presentations.
Shure BLX Wireless Systems combine professional-quality sound with simple setup and an intuitive interface for legendary audio performance right out of the box. Precision-built and available in a variety of configurations, it’s the most accessible way to own the stage. Includes power supply, lavalier clip, windscreens, and user guide.
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 FCC’s wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
