Shure BLX14/CVL Wireless Presenter System with CVL Lavalier Microphone
Low-Visibility Lavalier Mic Optimized for Speech
The Shure BLX14/CVL brings presenters, teachers, clergy, and lecturers a cost-effective wireless lavalier microphone system with quality sound, simple setup, intuitive operation, and dependable performance right out of the box. It includes the compact and lightweight BLX4 single-channel tabletop receiver with internal antennas, ideal for portable use.
The BLX14/CVL also includes a CVL cardioid lavalier mic with clip and windscreen, and a bodypack transmitter. The receiver features one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. The system provides up to 14 hours of continuous use with two AA batteries, at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band.
This streamlined system is well suited for hands-free speech in small venues, wedding halls, and houses of worship, as well as conference, educational, and corporate facilities.
The CVL Centraverse lavalier condenser microphone is built for low visibility and clear vocal reproduction. The mic features a cardioid polar pattern that rejects unwanted noise, Commshield RF Filtering to minimize RF interference from nearby smartphones, and a tailored frequency response optimized for speech intelligibility.
Lightweight Bodypack Transmitter
The durable BLX1 bodypack transmitter offers a lightweight, ergonomic design that is comfortable for the presenter to wear. Group and channel selection buttons allow for quick and simple frequency matching with the receiver. Other features include an easily accessible on/off switch, adjustable gain control, and a TA4M 4-pin input jack.
Easy-to-Use Tabletop Receiver for Quality Audio
The BLX4 receiver employs microprocessor-controlled internal antenna diversity to improve the quality and reliability of your wireless audio. An LED display shows group and channel settings, while two LED lights indicate when the system is ready for use and the strength of the incoming audio signal. The unit offers 1/4" and XLR outputs for connectivity to PA systems and mixing boards.
