UHF wireless desktop microphone U-714 kit of 4

Features

• With the UHF high frequency band, there is less interference than the traditional one so that the transmission is more reliable.
• With PLL technology, you can choose 200 frequency channels, which makes it convenient to use multiple sets at the same time and avoid interference types.
• IR sync. Frequency synchronization technology, the transmitter frequency can be automatically received by the microphone. The signal is stable and the anti-interference ability is improved.
• The transmitter and receiver have LCD screens, which they can display the working frequency and synchronize to the right IR frequency. The operation is simple, straightforward and convenient.
• The working distance is more than 60 meters.
• Both the receiver and the transmitter are made of high-strength alloy, so they are robust and durable.
• Microphone connector: BNC, 50 Ohm
