Overview

The Shure BLX188/CVL is a complete dual-channel wireless lavalier microphone system that provides professional audio quality in a package designed for quick, hassle-free setup. At its core is the BLX88 dual wireless receiver, which simultaneously manages two independent channels — each paired with a BLX1 bodypack transmitter and a CVL omnidirectional condenser lavalier microphone. This makes it a natural fit for two-person interviews, panel discussions, presentations, worship services, and any scenario where two speakers need hands-free microphones at the same time.

Operating in the UHF H11 frequency band with a range of up to 300 feet, the system offers reliable wireless performance for small to medium venues. Each bodypack transmitter delivers up to 14 hours of operation from two AA batteries, providing confidence for day-long events without scrambling for replacements. The CVL lavalier capsules are small and discreet with omnidirectional pickup, capturing clear vocal audio regardless of the speaker's head position. Included accessories — belt clips, clothing clips, windscreens, and batteries — mean you can be up and running minutes after opening the box. For larger productions, the BLX platform supports up to 12 simultaneous channels per frequency band, allowing the system to scale as your needs grow. XLR outputs on the receiver integrate seamlessly with mixers, PA systems, and recording interfaces.
