WL-207, 2.4G Wireless Digital Audio Module, Speaker Adapter, RX and TX Modules, 5V

2.4G Wireless Digital Audio Module, Speaker Adapter, RX and TX Modules, 5V

Using the latest 2.4G wireless transmission technology, 44.1K sampling rate, 24bit AD sampling lossless high-fidelity digital audio transmission, 16 selectable operating channels. Maximum distance 100 meters open ground. A closing situation, you can form a wireless audio transceiver system, simple and convenient.

Function Description

• Input signal: analog audio
• Output signal: Analog audio
• Working voltage: 5V
• GFSK digital modulation / demodulation
• Frequency Response 20Hz ~ 20KHz
• 90dB Audio Dynamic Range
• 85dBm receiving sensitivity, 45dB Adjacent channel rejection, 30dB image rejection
• Frequency Response 20Hz ~ 20KHz
• 44.1K digital audio sample rate, 24bit quantization samples

Transmission distance: more than 100 meters in open areas within the transmit stereo audio data (static point to point)

Support for multiple-point and multipoint transmission mode (both a fat multiple simultaneous closing)
Button on the code, which can support multiple parallel work without interference.

More than one alternative bands, easy to avoid interference frequency: The product operates in the 2.4GHz ISM (ie industrial, scientific, medical) band, there are 16 selectable frequencies, multi-frequency and frequency hopping to meet needs; to avoid in the 2.4GHz public frequency band interference prone to impact on the quality of the product provides a frequency selection function, if the product in the course of it’s function delivers a strong noise, that is, in the presence of interference affecting the current frequency output quality, the optional new working frequency, in order to maintain product good use of effects. 

Features

1. Module size: transmitter module 50 x 20 (mm); receiver module 47 x 20 (mm)
