CR-1 Single Channel Wireless Microphone System

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.

Characteristic
• UHF wireless transmission, providing high fidelity sound source.
• Widely compatible with smart phones, digital SLR cameras, portable cameras, tape recorders, tablets, etc.
• Digital audio compression of DSP reduces the noise in wireless transmission system to the lowest level.
• 10 switchable frequencies to realize the operation without environmental interference.
• The volume of receiver and transmitter can be adjusted arbitrarily to adapt to the volume level of different equipment.
• Real-time monitoring function with headphones.
• Receiver and transmitter are powered by two AA batteries.
