  • Allows operation of up to 4 compatible systems in a typical setting, and up to 8 maximum under ideal conditions
  • Operating range Indoors: Up to 100 feet (30 m) typical, with a maximum of 200 feet (60 m) under ideal conditions
  • Operating range Outdoors: Up to 65 feet (20 m) typical, with a maximum of 165 feet (50 m) under ideal conditions

The SM35 headset condenser microphone from Shure gives multi-instrumentalists the freedom to express themselves without having to sacrifice the sound quality found in traditional microphones. A tight, unidirectional (cardioid) pickup pattern provides excellent rejection of off-axis sound sources to prevent feedback and signal bleed for superior performance on stage. Standard TA4F (TQG) connectivity seamlessly integrates into any Shure wireless bodypack system, and its availability in a number of bundled systems makes it appropriate for any stage, ranging from small clubs to large installations and arena tours.

LINKFREQ Automatic Frequency Management (2.4 GHz frequency band)

  • Revolutionary intelligent frequency management quickly identifies the best open group and channel frequencies
  • Bi-directional communication link automatically enables the transmitter to follow any frequency change on the receiver
  • Continuous interference monitoring automatically and seamlessly switches to backup frequencies if needed, without performance interruption
