2.4G Wireles HDCD Audio Transmiter Receiver Transmission Module Testing Board

Features:
Long transmission distance: can transmit stereo audio data within 180 meters open ground (open and no obstacle,testing results when receiver and transmittera are in static state)
Supports point to point,point to multipoint transmission modes,support an unlimited number receivers
Up to 30 optional frequency, easily avoid interference frequency: the product in the 2.4GHz ISM (industrial, scientific and medical) band, there are 30 optional frequency, which can meet the needs of multi frequency and frequency hopping.To avoid the influence of interference on sound quality,interface can occur in the 2.4GHz public frequency band. The product provides a frequency selection function, if trong noise occures in the process of working,that's is the current frequency point exist interference effect for output quality,customer can choose new the working frequency to maintain good performance.
- The shortest delay: wireless transmission audio delay is less than 0.5ms, the highest standards in the industry.
- The highest audio sampling rate is 64K, high fidelity HDCD sound effects: sampling frequency breaks through the former limitations, uses high quality 64K digital audio sampling rate.16bit sample quantization level,ensuring the quality of transmission from the source.Through special processing technology to ensure high fidelity effect of the received signal.
- 20Hz to 20KHz frequency response
