2.4GHZ digital wireless speaker transmitter and receiver system

Data specification:

Feature:

1. Long distance transmission: The stereo audio data can be transmitted in over 180 meters open area (no obstacle, the test result is based on static status)
2. The first company in industry which can provide digital wireless audio transmission modules with I²C interface,the customer can access up to 128 grades digital volume control and realtime channel adjustment.
3. Support channel up and down: Totally 20 channels for adjust,and can be extend to 80 channels max.
4. Support volume up and dowm:there are 32 grades volume available for adjustment.Can be extend to 128 grades max.
5. Supporting point to point and point to mass transmission modes with unlimited number of receivers.
6. Up to 20 selectable channels, easily avoid interference: the item works in 2.4GHz ISM (namely Industrial, Scientific, Medical) band, with 20 channels for selection, meeting the needs of Multi-frequency and frequency hopping. If there is strong noise during working, i.e. there is interference in current frequency, users can choose a new channel to get a good effect.
7. The shortest sound delay: The delay of audio wireless transmission is less than 0.5ms, which is the top standard in industry.
8. The highest audio sampling ratio 64K, Hi-Fi HDCD sound quality: Break through the previous limitations, adopting high fidelity 64K digital audio sampling rate and 16bit sample quantization, therefore the sound quality is ensured from the source, and the special technology treatment before and after transmission to ensure the received signal keeping Hi-Fi effect.
9. 20Hz ~20 KHz frequency response: Please note that it’s an actual test data, quite different from some products in the markets which don’t meet this standard but be marked with exaggerated advertisement.
10. SOYO unique method of random pairing mode: Users can select point to point or point to mass pairing mode following manual instructions. As high as 20 million pairing codes are released at random by system, the repeat possibility is only 1/20,000,000, easily ensure users’ privacy not to be violated.
11. Special encrypted transmission: SOYO marked the first in the industry adopted unique audio coding with unique code encryption method to achieve the encryption transmission of audio data. Thus only our customers can receive the audio transmitted from our products.
12. Ultra-low power consumption design: The lowest power consumption provided in the industry, the transmitter current can be adjusted from 40mA -110mA directly based on users’ request, the receiver current is lower than 35mA, and the current is less than 5mA in standby.
13. World’s first output mode compatible with microphone and stereo audio: We developed the first wireless audio transmission module which is compatible with both microphone input and stereo audio input in the world. It’s convenient for factories to develop various wireless microphones/ wireless audio/compatible wireless microphone and wireless audio products based on the same program quickly, accelerating development cycle.
14. Supporting 2 digits display of current channel: The own display interface of module can display the channel digit, which facilitates the development of high-end wireless audio products.

1. Small size: Both transmitter and receiver modules are as small as the size of a thumb, one of the most micro-sized modules in the field, convenient for developing various portable wireless audio applications.
2. Output power: 60mw audio output power facilitates the development of portable headphone audio products, save the Circuit cost and accelerates the development cycle.
3. Multi antennas can be provided, including built-in Copper antenna / built-in high gain antenna / external antenna / high gain external antenna, seamless support provided for product development.
4. A variety of versions: following versions can be offered by now

      Optional Sampling ratio: 10k / 44.1k / 64k

      Optional microphone input gain: 0dB / 20dB

      Channel selection ways: manually operated / automatically operated

      Power adjustment: We provide power adjustment function from 1mw to 100mw on software, that’s convenient for different

applications:

1. FCC/CE passed: The module and series version SOYO-WM24G02 have got FCC and CE approved, and obtained the relevant certificates.
2. Strict quality management and control: Our products, which are made of high quality accessories from excellent electronic components manufacturers in the field. All the products are qualified and passed the strict 24-hour aging test before delivery, which ensure all the products we offer to customers are 100% qualified.
3. Assessment testing tools to be provided: We provide important customers with test board along with delivery, convenient for module testing at customers’ side.
4. Wide applications: The product is fully taken account of easy using and compatibility, with various audio and data interface provided, supporting the matching with third-party audio products, easy using, plug and play; furthermore, it’s able to transform the current Sound box, headphone, microphone, loudspeaker and electronic musical instruments into wireless ones.
