Shure BLX288E/SM58-K3E

Shure BLX288E/SM58-K3E Wireless Dual Vocal System

The Shure BLX288E/SM58-K3E pairs two SM58 cardioid dynamic capsules with the BLX88 tabletop receiver on the K3E band (606-630 MHz). It is built for two simultaneous presenters, singers, or worship leaders needing reliable, cable-free vocal performance in small to mid-sized venues. The system combines Shure's proven analog wireless platform with the SM58's industry-standard vocal character, delivering warm, clear reproduction. Setup is simple — power on, run QuickScan, and the receiver locks onto a clean frequency in seconds.

What sets this dual wireless system apart

Inside each handheld transmitter sits the SM58 capsule with a built-in pneumatic shock-mount that cuts handling noise and a spherical wind/pop filter that tames plosives without external foam. The BLX88 receiver uses microprocessor-controlled internal antenna diversity to keep the RF link stable, while one-touch QuickScan automatically searches 123 available frequencies and selects the cleanest channel. Both transmitters include a -10 dB gain attenuation switch for loud vocalists, and the rugged BLX2 housings are built for daily stage use.

Wireless performance and capsule specifications

The SM58's tailored 50 Hz to 15,000 Hz response shapes every signal before it leaves the transmitter. The BLX88 receiver accepts up to 12 compatible systems per band, and each BLX2 transmitter runs up to 14 hours on two AA batteries with a 100 m (300 ft) line-of-sight range. Outputs include both XLR and ¼" jacks, and a two-color LED on the receiver indicates normal (green) versus excessive (red) audio levels.
