Shure BLX24UK/SM58-H8E Wireless Vocal System with SM58 Handheld Mic

Features:

• RELIABLE SIGNAL – Extend your range
  With a range of up to 300 feet (100m), you can take the show into the crowd without interruption.
• EASY SETUP – Own the stage
  BLX will have you up and running in record time with one-touch scan and selection.
• BATTERY LIFE – 14 hours of power
  Because BLX transmitters get up to 14 hours of power from a single pair of AA batteries, the show can go on and on (and on).
• SYSTEMS EXPANSIONS – Run up to 12 channels per frequency band*
  You’ll probably need to find a bigger stage before you run out of channels.
  *Note: region and environment dependent.
