Shure BLX288/PG58-J11 Dual Wireless Microphone System

The Shure BLX288/PG58-J11 is a dual-channel wireless vocal system built for two performers, presenters, hosts, or speakers who need dependable handheld microphone operation without cables. It combines a BLX88 dual receiver with two BLX2 handheld transmitters fitted with PG58 dynamic microphone capsules. The J11 version operates in the 596–616 MHz frequency band, so buyers should confirm local spectrum authorization before use.

Designed for live sound, houses of worship, schools, DJs, karaoke, meetings, and small stage setups, this system gives two users independent wireless channels from one compact receiver. The BLX88 provides separate audio sections for each channel, allowing each microphone to be connected to a mixer, powered PA system, or amplifier. Its line-of-sight operating range is rated up to 300 feet, although actual range depends on RF conditions and obstacles.

The included PG58 capsules use a dynamic cardioid design suited to speech and vocal performance. Their directional pickup pattern focuses on the person using the microphone while helping reduce pickup of surrounding sound. This makes the system a practical choice where clear voice reinforcement is the priority.

Shure BLX wireless technology uses an analog UHF design with microprocessor-controlled internal antenna diversity in the receiver. One-touch QuickScan frequency selection helps locate an available operating frequency when interference is present. The BLX2 transmitters also provide a selectable -10 dB attenuation setting for louder sources.

The system is ready to form the front end of a two-microphone PA setup and includes the core hardware needed to begin operation. Each transmitter runs on two AA alkaline batteries for up to 14 hours under typical conditions. For larger wireless deployments, BLX supports up to 12 compatible systems per frequency band when regional spectrum conditions allow.

Design & Installation

The BLX88 receiver and BLX2 transmitters use molded ABS housings designed for portable wireless-audio use. The receiver has internal antennas, two-color audio status LEDs, and separate group and channel controls for its two channels. Each handheld transmitter incorporates its PG58 microphone capsule and has a battery compartment for two AA cells.

Place the receiver where its internal antennas have a clear path toward the performance area, then connect its XLR or 1/4-inch outputs to compatible inputs on a mixer, powered speaker, or amplifier. Use the receiver's group scan and channel scan functions before matching each BLX2 transmitter to its assigned receiver channel. The package includes the receiver, two handheld transmitters, two microphone clips, a power supply, four AA batteries, and a user guide.
