Overview

Shure BLX188/CVL

The BLX188/CVL is Shure's two-channel wireless presenter system: a BLX88 dual-channel tabletop receiver paired with two BLX1 bodypack transmitters, each wired to a CVL lavalier microphone — built for co-presenters, panel discussions and dual-host productions. Note: Shure's own naming designates this specifically as a dual-channel (two bodypack, two lavalier) system, not a single-bodypack configuration.

Each channel offers independent one-touch QuickScan frequency selection, up to 14 hours of battery life per transmitter, and up to 12 compatible systems on one frequency band, depending on region and environment.
