Complete Wireless Lavalier System

The Shure BLX14/CVL combines the essential components needed for a professional wireless lavalier microphone setup.

The system includes:

• BLX4 single-channel wireless receiver
• BLX1 bodypack transmitter
• CVL Centraverse cardioid lavalier microphone

This combination provides a convenient wireless solution for applications where clear speech and hands-free operation are important.

CVL Centraverse Lavalier Microphone

The included Shure CVL Centraverse is a compact electret condenser lavalier microphone designed for professional speech and presentation applications.

Its cardioid polar pattern focuses pickup toward the speaker while helping reduce unwanted sound from the surrounding environment. A tailored frequency response provides clear, intelligible speech for presentations, lectures, services, meetings, and other spoken-word applications.

The microphone's compact design allows discreet attachment to clothing, making it well suited for presenters who need a low-profile hands-free microphone.

The CVL uses a TA4F connector for direct connection to the included BLX1 bodypack transmitter.

BLX1 Wireless Bodypack Transmitter

The included Shure BLX1 is a compact, lightweight bodypack transmitter designed for use with Shure BLX Wireless Systems.

Its TQG input connection accepts the included CVL microphone and is also compatible with select Shure lavalier, headset, earset, and instrument microphones.

An adjustable gain control allows the input level to be matched to the connected microphone, while the easily accessible On/Off switch provides convenient control during presentations and performances.

Powered by two AA alkaline batteries, the BLX1 provides up to 14 hours of battery life for extended use.

BLX4 Single-Channel Wireless Receiver

The Shure BLX4 is a single-channel wireless receiver designed for straightforward setup and dependable operation.

Shure's one-touch QuickScan frequency selection helps locate an available operating frequency, simplifying wireless setup in schools, churches, meeting rooms, performance spaces, and other venues.

The receiver uses microprocessor-controlled internal antenna diversity to support reliable wireless reception.

Audio connections allow the receiver to be integrated with professional mixers, amplifiers, powered speakers, and installed sound systems.

QuickScan Frequency Selection

Setting up a wireless microphone system doesn't need to be complicated.

The BLX4 receiver features one-touch QuickScan frequency selection, which helps identify an available operating frequency for the system.

Once the receiver is configured, the BLX1 bodypack transmitter can be matched to the receiver for operation.

Actual wireless performance can vary depending on the RF environment, interference, physical obstructions, and other conditions at the installation or event location.
