Shure BLX1288/CVL-H9 Dual Wireless Handheld & Lavalier System

The Shure BLX1288/CVL-H9 is a dual-channel UHF wireless microphone system designed to put one handheld vocal microphone and one lavalier microphone on the same receiver. It is suited to presentations, worship services, classrooms, event production, karaoke, and small performance setups where two speakers or performers need independent wireless channels. The H9 version operates from 512 to 542 MHz, so users should confirm local frequency authorization before purchase and operation.

This package combines a BLX2 handheld transmitter fitted with a PG58 dynamic cardioid capsule and a BLX1 bodypack transmitter paired with a CVL cardioid condenser lavalier microphone. The handheld option is useful for vocalists, hosts, and audience participation, while the lavalier supports hands-free speech applications. Both transmitters use two AA batteries and are rated for up to 14 hours of alkaline-battery operation.

The BLX88 receiver provides two independent receiver channels in a compact tabletop format. Each channel has its own XLR microphone-level output and 1/4-inch instrument-level output for connection to a mixer, powered speaker, amplifier, or PA system. Microprocessor-controlled internal antenna diversity and QuickScan frequency selection help simplify setup in changing RF environments.

System audio performance is specified at 50 Hz to 15 kHz, with a typical dynamic range of 100 dB and typical total harmonic distortion of 0.5%. The CVL lavalier uses a cardioid pickup pattern to focus on the wearer, while the PG58 handheld capsule also uses a cardioid pattern for controlled vocal pickup. Receiver audio-status LEDs show normal signal level in green and overload in red.

The BLX1288/CVL-H9 can be a practical foundation for a two-person wireless setup without requiring separate receivers for each microphone. Additional compatible BLX systems can be coordinated in appropriate RF conditions, with up to 12 compatible systems per band depending on the environment. For larger installations, set up and scan each system sequentially while keeping already assigned transmitters powered on.

Design & Installation

The BLX88 receiver, BLX1 bodypack, and BLX2 handheld transmitter use molded ABS housings. The receiver has front-panel group, channel, and power controls with status LEDs, while the bodypack includes a TA4 microphone input and adjustable gain control. The handheld transmitter includes group and channel controls plus selectable default or -10 dB gain operation.

Place the receiver where it has a clear path to the transmitters and connect each required receiver channel to a mixer or PA using XLR or 1/4-inch outputs. Run a group scan before use, then set each transmitter to the matching receiver group and channel. Attach the CVL microphone with its supplied tie clip, position it approximately 6 to 10 inches from the speaker's mouth, and use the supplied microphone clip for the handheld transmitter when stand mounting is needed.
