8011D system, 638-674MHz


  • RU-8011D receiver
  • RU-850TB belt-pack transmitter
  • CM-501 lapel mic




Based on US-8001 successful experience, RU-8011 is designed with JTS 2nd generation REMOSET technology. To cope with the squeezed radio spectrum the system provides more compatible channels within limited bandwidth. The REMOSET technology sends the scanned channel data to transmitter by pushing a button. To meet critical audio demand general noise and hiss noise have been reduced to an extremely low level. 100 meter operation range meets most demand from most applications. To be environment friendly an integrated charger is available on option.
