The system ships with a BLX4R half-rack single-channel receiver, bodypack transmitter and a WA302 1/4-inch instrument cable. It is intended for guitarists and bassists who want cable-free stage mobility with a conventional 1/4-inch connection at the bodypack end.
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.
