Features: UHF Frequency Transmission: It adopts UHF (Ultra high frequency) band transmission, with frequency range. Frequencies can be designed according to the regulations of the country in which they are actually used, so as to be suitable for various countries and regions. Micro-computer CPU Controlled: The hardware circuit of the whole system is controlled by the CPU of the microcomputer. It can select frequency, display frequency and frequency data etc. It can realize various functions that are not easy to realize in traditional models. Wide and Clear LCD Display: With high performance, wide and clear LCD display, all operations can be displayed on the LCD screen to facilitate users to understand the working status of the system and set up the system. Display content includes: radio frequency signal strength, audio signal strength, channel and frequency, ACT working status, etc. High Precision PLL Technology: The PLL technology with high precision phase-locked loop frequency synthesis has higher frequency stability and excellent frequency selection characteristics. It can realize multi-channel and multi-functional professional functions in the system. Channel Selection: The system is with channel selection, and the user can set the working channel according to the actual needs by very simple and convenient operation. Audio Output: The audio output is equipped with XLR balanced output and 1/4 inch unblanced output, which makes it easy for users to connect to different external devices. Automatic Channel Tracking(ACT): The system has high-tech automatic channel tracking function. After the receiver has set up the receiving channel, the transmitter frequency can be locked automatically and accurately by infrared data transmission, so that the trasmitting frequency can be synchronized with the receiver. Anti-interference Multi Channels Design: The system uses a variety of anti-interference technology. It has 160 noninterference frequencies as the factory default setting. It is reasonable to design and convenient for users to use multi-system at the same time. It is an ideal product for speech and conference rooms. Battery Status Indicator/ Lower Power Warning: The battery power of handheld transmitter, bodypack transmitter and conference transmitter can be displayed on their LCD, and the warning is given when the battery power is low, promptly reminding users to change batteries to ensure the normal operation of the system. Modular Mic Capsule Design: The Mic capsule of the handheld transmitter adopts modular design, which can facilite users to configure different sound quality Mic capsules to adapt to different occasions.
