A.Product Introduction UHF multi channel wireless system is a intelligent multi functional wireless system, adopts UHF multi frequencies design, PLL technology, ultra high frequency wireless transportation, with stable quality, long working distance, clear sound quality, wide and clear LCD display and fashionable outlook design. This system is suitable for professional stage, multi function hall, conference rooms and teaching rooms. 1 UHF Frequency Transmission Advantages It adopts UHF (Ultra High Frequency) band transportation, with frequency range for 610-960MHz.Frequencies can be designed according to the regulations of the country in which they are actu-
ally 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 micro-computer. It can select frequency, display frequ-
ency and process 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 operat-
ions can be displayed on the LCD screen to facilitate users to und-
erstand 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 Compared with the quartz-controlled system, the PLL technology with high precision phase-locked loop frequency synthesis has higher frequency stability and excellent frequency selection char-
acteristics. It can realize multi-channel and multi-functional prof-
essional 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 conven-
ient operation. Audio Output The Audio output is equipped with XLR balanced output and 1 UHF Microphone System Technical Parameters UHF Microphone System System Components 1/4 inch unbalanced 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 (ACT) function. After the receiver has set up the receiving channel, the transmitter frequency can be locked automatically and accur-
ately by infrared data transmission, so that the transmitting frequency can be synchronized with the receiver. Anti-interference Multi Channels Design The system uses a variety of anti-interference technology. It has 160 non-interference frequencies as the factory default s-
etting. 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 trans-
mitter 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 oper-
ation of the system. Modular Mic Capsule Design The Mic capsule of the handheld transmitter adopts modular design, which can facilitate users to configure different sound q-
uality Mic capsules to adapt to different occasions. 2.Technical Parameters System 470.2 MHz- 607.7MHz FSK Frequency ranges:

Please check the guidance above for the IR synchronization for the transmitters from the single system setting. E.Tips for improving system performance
*l The transmitter and antenna should be kept in an accessible linear relative position.
*l Do not place the receiver close to the metal surface or close to any digital device (such as CD player, computer, etc.).
*l The receiver should be protected above 1M from the ground and not close to the wall as far as possible.
*l Transmitting devices such as cellular phones and bidirectional radios interfere with audio transmission. Transmitters and receivers should be kept away from these devices and other potential sources of inter-
ference. 20 21 UHF Microphone System Connection UHF Microphone System Troubleshooting F.Connection 1.Connection instructions for dual channel models (figure 12) DC INPUT ANTENNA-B BAL- OUT MIX CUT BAL - OUT ANTENNA-A Figure12) 2.Connection instructions for four channel models (figure 13) DC INPUT ANTENNA-B MIX CUT BAL-D OUT BAL-C OUT BAL-B OUT BAL-A OUT ANTENNA-A Figure13) 3.Connection instructions for four channel models (figure 13) DC INPUT ANTENNA-C ANTENNA-D BAL-H OUT BAL-G OUT BAL-F OUT BAL-E OUT ANTENNA-A MIX CUT BAL-D OUT BAL-C OUT BAL-B OUT BAL-A OUT ANTENNA-B Figure14) 22 G.Troubleshooting Problem No operation indication No RF signal RF signal available, no audio signal,M-
