Shure BLX288/SM58 Dual Vocal System
The Shure BLX288/SM58 is a two-channel analogue wireless system pairing a BLX88 dual receiver with two BLX2 handheld transmitters fitted with SM58 vocal capsules. One-touch QuickScan frequency selection finds a clean channel quickly, and the system works at line-of-sight ranges of up to roughly 100 metres. Each transmitter runs up to 14 hours on two AA batteries, and up to 12 compatible systems can operate in the same frequency band, making it a practical entry-level choice for churches, conference rooms and small-to-mid-size stages.
Available from Sound Creations Ltd Rwanda in Kigali, with manufacturer warranty and local after-sales support.
