S-9100 Infrared Wireless Microphone

International standard UHF 800MHz band, away from outside interference This series of products using UHF800MHz working band, the specific frequency range 730-950MHz, can be used as an international standard frequency bands. Compared with the low-frequency VHF band, UHF800MHz frequency spectrum resources with wide, electromagnetic space clean, the outside world advantages of less interference can be avoided greater external devices, such as VCD, DVD video and other outside interference devices work properly. multiple user adjustable frequency interval by practical design, to ensure the use of multi-machine at the same time This series of products using microprocessor-controlled, PLL frequency synthesizer technology to overcome the common locking the chip, the circuit mode frequency products more than the existence of sub-carrier, spurious interference with large defects, and have multiple users chirp rate, you can easily change the operating frequency in order to use multiple machines simultaneously, it can easily avoid outside interference. superheterodyne dual conversion design, with high receiver sensitivity This series of products using superheterodyne frequency design, there is a breakthrough way of a conversion is difficult to balance the gain and stability of the defects, both with high gain, they will not gain too high and cause self-excited, the system has excellent stability . multi-level high-performance SAW filter, with excellent anti-jamming capability This series of products in the high level class and the first IF amplifier stage are used with perfect filtering properties of the SAW filter, IF amplifier stage using the second consistency of fine ceramic filters, has been selected frequency characteristics of excellent, greatly improved the anti-jamming capability configuration LCD screen display channel number and frequency, work status at a glance This series of products, a number of models equipped with LCD screen, showing a number of key information to make operation and monitoring easy and convenient, resulting in improved performance. Professional Audio Output: XLR balanced output and unbalanced output ¢ 6.3 This series of products, all with independent balanced XLR output and unbalanced mixed output coexist ¢ 6.3mm way to adapt to the devices on various occasions, because the device does not match to avoid causing confusion and embarrassment. automatically muted and the impact of elimination of circuitry, eliminating the impact of switching machines and other noise All products in this series and have automatically mute the impact of elimination of circuitry, eliminating the impact of the switch, to avoid the impact and noise impact of the atmosphere or even damage the PA equipment and speakers. Double boost transmitter circuit design, the battery charge does not affect the transmitter power All products in this series dual boost the microphone circuit design, audio circuitry required for high voltage and high frequency circuits are required by low voltage DC-DC converter circuit to obtain, and thus the impact from the battery voltage drop to maintain a constant transmit power , so there is no longer battery life, power down the more the phenomenon of shorter operating distance. High reliability surface technology (SMT) production This series of products are all high stability and high reliability surface mount components, the application surface mount technology and production process, and apply the screening process of aging, discovery and elimination of early failure of components, compared with the normal pin components, significantly improved product stability, reliability and service life Infrared automatic frequency, simple Working distance: 100 meters The use of advanced technology pilot, external interference signal shielding, multiple stacked machines simultaneously, no interference, KTV room, folding machine used by the receiver panel SQ potentiometer adjustment, simple operation, LCD large LCD display, with RF / AF intensity display, set the channel, frequency, squelch, at a glance. Launch microphone 2 1. 5v (5 #) or a 9v battery stack, LCD shows channel, frequency, battery at a glance
