Shure BLX288/PG58-H10 Dual Wireless Vocal Microphone System

The Shure BLX288/PG58-H10 is a dual-channel UHF wireless microphone system designed to put two handheld vocal microphones into one straightforward setup. It pairs a BLX88 dual receiver with two BLX2 handheld transmitters fitted with PG58 vocal microphone capsules. It is suited to presenters, singers, karaoke setups, houses of worship, schools, and small live-event systems that need two wireless vocal channels.

Each handheld transmitter uses a cardioid PG58 vocal capsule to focus on the person using the microphone while helping reduce pickup from the sides and rear. The system's analog wireless design provides a specified audio range of 50 Hz to 15 kHz, dependent on microphone type. This makes it a practical option for speech and vocal reinforcement through a compatible mixer, powered speaker, amplifier, or PA system.

The H10 version operates in the 542–572 MHz UHF frequency band. Before use, confirm that this band is appropriate and available at the intended location, since wireless microphone frequency availability depends on local conditions and regulations. The system supports up to 12 compatible channels per frequency band, with actual capacity depending on the region and RF environment.

For setup, the BLX88 receiver uses one-touch QuickScan frequency selection to locate an available frequency when interference is present. Its microprocessor-controlled internal antenna diversity is designed to support stable reception, while audio-status LEDs show normal audio in green and overload or clipping in red. The stated operating range is up to 300 feet under suitable conditions.

The two BLX2 transmitters run on standard AA alkaline batteries and provide up to 14 hours of stated battery life per pair. Each transmitter includes a -10 dB gain attenuation option for accommodating louder vocal sources. The BLX88 receiver supplies XLR and 1/4-inch audio outputs, making it suitable for integration with many conventional sound systems.

Design & Installation

The system combines molded-ABS BLX88 receiver and BLX2 transmitter housings with an integrated PG58 microphone-capsule design. The handheld transmitters are lightweight and include an on/off switch plus a selectable -10 dB attenuation setting. The receiver uses internal antennas and front-panel audio and RF status indicators for clear system monitoring.

Place the receiver where it has a clear practical path to the performers, connect its XLR or 1/4-inch outputs to compatible mixer or PA inputs, and connect the included power supply. Install two AA alkaline batteries in each transmitter, then use QuickScan and match the selected group and channel as directed in the user guide. Use the supplied microphone clips for stand mounting when handheld use is not required.
