UHF dual channel wireless receiver can receive two wireless microphones or two lapel microphone or a handheld microphone and a lapel microphone, and parallel to control the microphone volume. Quartz lock with a fixed frequency UHF band, with the latest "noise detection" mute control, it can completely eliminate the noise generated by loud noise interference. Dual-channel receiver audio output is a mixture of two-channel output, and separate balanced output can meet the input characteristics of a variety of Amplifiers. Metal chassis and SMT circuit, there are 30 groups frequencies between 760-920 MHz for choice . Product Features: Frequency Range: 740-920MHZ Modulation System: quartzcrystal control Rf stability: 0.005%(-10-50) Frequency Resopone :50Hz-18KHz3dB RF Power:10mW Noise Ratio:>100dB T.H.D: 0.5%.

Condenser Microphones
It can eliminate almost background noise and echoes. Heavy duty throat mic with acoustictube for all interphones. Designed with a vibration sensor attached to neck near the vocal cord. The sensor will only pick up the skin vibration signals from vocal cord when talking, rather than the air vibration signals from mouth and the environment. Therefore, the background noises and echoes are almost totally eliminated. Standard box of power time
The wireless microphone products is using bluetooth wireless transmission technology, compared to traditional wireless microphones, the products have following features. 1.The farthest distance of the received signal can be transmittled up to 100meters 2.Voice clear mission 3.Many mircophones can be using at same time without disturb. 4.Easy to expansion quantity. 5.For customers different needs, we have three style can for their choice (with hand-held, waist hanging, conference-specific desktop, etc) 6.Easy to connect pa amplifier and other equipment. 7.Accessories simple and easy to carry. 8.The mircophone is using battery, it can be using for more than hours for one charging. And there are two ways for charging (1. Usb port connected to the computer charge; 2. Using transformer to connect ~220 v to charge.) 9.Customized design: some details can be customized production depending on clients special needs ( in order to distinguish the different user of school teacher, we can make the mircophone with different colors rubber rings. ) When user using the equipment, just connect the receiver to speaker, and the user holding the microphone, turn on the microphone and receiver í«s power swithc on, then the bluetooth system will automatically match, users can normally use the porducts. The products is suitable for teaching , meeting rooms, lectures, family and kara ok hall , singing and oterh accasions. Standard configuration: a wireless microphone, a receiver, a usb prot connection cable
The high-frequency module is used exclusively for uhf wireless mic. With audio circuit, transmitting module (tx) could be made into a complete wireless speaker or belt-pack transmitter. Receiving module (rx) consists of noise amplification, one time frequency mixing, twice mixing, local oscillation, mcu frequency control and other functions. With audio circuit, it could be made into a complete wireless mic receiver. By applying d2008 directly, factories could simplify design and production of uhf wireless mic, and adopt the module easily in mining industry and electronic consumer system equipments.
D2009 may be applied in low-cost uhf and vhf wireless mic. With multiple frequency points pll, it may replace widely used single frequency point crystal in the market, and be easily embedded in wireless voice transmission and amplification in mining industry and electrical consumer systems. Together with audio circuit, transmitting module (tx) may be made into a complete wireless speaker or belt-pack transmitter. The receiving module (rx) is characterized by noise amplification, frequency mixing, local oscillation, mcu frequency control and other functions. Together with audio circuit, it may be made into a complete wireless mic receiver.
