Relacart CR1 Single Channel Wireless Microphone System

Relacart CR1 Single Channel Wireless Microphone System

• RF carrier frequency range: 470MHz-960MHz
• Dynamic range: 85 dB
  
• Image rejection: 45dBm

CR-1 Is a highly cost-effective UHF wireless microphone system, compatible with smart phones (3.5mm interface), digital/SLR cameras, portable cameras, recorders, tablets and other equipment to help pick up high-fidelity audio. It is suitable for interviews, microfilm recording or commercial demonstrations and other applications. The transmitter supports microphone input interface, and the receiver has earphone monitoring function. The effective working distance is about 80 meters in the open space. Both transmitter and receiver have the function of key lock to prevent user from misoperation.
