The Shure BLX Dual Wireless System, featuring two PG58 Handheld microphones, delivers professional, interference-free performance for singers, speakers, and performers. Operating in the 606MHz-630MHz frequency band, it combines Shure sound quality with wireless freedom. Each PG58 transmitter provides 14 hours of runtime and up to 100m of range, while the BLX88 dual receiver utilises QuickScan technology to find the clearest frequency for both channels.
