2.4G Digital Wireless Audio Module2.4ghz digital wireless audio module, has the following characteristics:

1, Transmission distance: Can transfer stereo audio data for more than 180 meters in open areas.

2, Support one point to one point or one point to multipoint transmission mode

3, a number of alternative bands, easy to avoid interference frequency: the product work in the 2.4GHz of the ISM (ie industrial, scientific, medical) band, there are 20 selectable frequencies (125 bands can be achieved as optional), can meet the needs of multi-frequency and frequency-hopping; In order to avoid the interference in the 2.4GHz band and the effects of interference on the sound quality, the product provides a frequency selection, if in the course of operation, there was a strong noise appears , that is, there was interference in outputing sound at the current frequency,there is an option to new work frequency in order to maintain a good product using effects.

4, HDCD(High Definition Compatible Digital) high-fidelity sound effects: the sampling frequency breaking through the limitations,and using the most fidelity of 64K sampling frequency as sampling, ensure the sound quality from the source, before and after treatment technology to ensure that the received signal has high-fidelity

5, wide range of application: product fully into account the ease of use and compatibility, external provision of a variety of audio and data interface, support cooperation of third-party audio products, the product can be directly connect to the audio input and output port, has a flexiblility of using, " Plug and Play, ", cooperate with existing products like speakers, headphones, microphone and further more achieve the wireless speakers, wireless headphones, wireless microphone (microphone).

6, specifications
