The Shure BLX288UK/B58-K3E is the K3E band variant of the Shure BLX analogue UHF wireless system. The system ships with a BLX88 dual-channel tabletop receiver, two handheld transmitters fitted with two Shure Beta 58A supercardioid dynamic vocal capsules. It is aimed at venues, houses of worship and corporate events that need two independent vocal channels from a single receiver.
LicensingIn the UK, 606 to 613.5 MHz falls under Ofcom’s Channel 38 shared licence; frequencies above 613.5 MHz within the K3E tuning range require a site-specific coordinated PMSE licence from Ofcom. Operators must hold the appropriate licence before use.
