The BLX14/CVL Lavalier Wireless System from Shure includes a BLX4 single-channel wireless receiver, a BLX1 bodypack transmitter, and a CVL lavalier mic. The system is set to Shure's K12 frequency band and operates between 614 - 638 MHz.
The BXL1 bodypack transmitter has a 300' line of sight operation range with the BLX4 receiver. It is powered by two included AA batteries that can provide up to 14 hours of operation. The BLX4 receiver features microprocessor-controlled internal antenna diversity that helps prevent interference and signal dropouts. Its one-touch QuickScan feature detects the most interference-free frequency and sets the channel to it for fast setup.
The CVL Centraverse Lavalier Condenser Microphone from Shure is a miniature lavalier condenser microphone that is optimized for speech and vocal performance. A tie clip and windscreen are included.
The BLX4 Single-Channel Wireless Receiver from Shure is a single-channel receiver set to Shure's K12 frequency band and operates between 614 to 648 MHz. It has microprocessor-controlled internal antenna diversity for reduced signal interference and dropouts. The one-touch QuickScan frequency selection feature allows you to quickly locate the frequency with the least amount of interference available.
Its front-panel dual-color LED status indicator displays green for normal levels and red when clipping for fast metering. It has an XLR output in additional to an instrument level ¼" output. The BLX4 can be used with up to 11 other compatible systems simultaneously per frequency band.
The BLX1 Bodypack Transmitter from Shure is designed for use with Shure's BLX wireless systems. It is set to the K12 frequency band and operates between 614 and 638 MHz. It has a TQG input and can be used with Shure lavalier, headset, earset and instrument microphones. With the optional WA302 adapter cable, the BLX1 can be used as a transmitter for guitar. The unit has a top panel mounted on/off switch as well as volume control for quick access while speaking or performing. The BLX1 is powered by the two included AA batteries for up to 14 hours.
