Shure BLX188/CVL Dual-Channel Wireless Cardioid Lavalier Microphone System

The Shure BLX188/CVL-J11 is a wireless lavalier microphone system with two independent channels that lets two presenters speak clearly while moving freely. It arrives ready to work right out of the box, pairing each included CVL cardioid lavalier microphone with a BLX1 bodypack transmitter and routing both signals to the compact BLX88 tabletop receiver.

Day-to-day operation feels straightforward. A single button on the receiver activates QuickScan, which automatically selects the cleanest frequency from 123 available options. Commshield technology blocks common sources of radio interference, so the audience hears the message, not the noise. Each transmitter runs for as long as fourteen hours on a pair of AA batteries, and the system keeps a solid link with its microphones at distances up to three hundred feet.

Connection to a mixer, powered speaker, or conference room audio interface is simple because the receiver offers balanced XLR output alongside an unbalanced 1/4-inch jack. Both outputs remain active at the same time, giving you flexibility to feed a recording device while also sending sound to the house system.

This dual-presenter setup fits naturally in classrooms, corporate training rooms, houses of worship, and rental inventories that support panel discussions or stage events. Anyone who needs hands-free speech reinforcement—whether they are leading a workshop, guiding a tour, or officiating a ceremony—will appreciate the clear sound and quick setup.
