AW2403T wireless digital audio transmitter module
AW2403T is our newly developed wireless digital audio transmission module, which uses the most common 44.1K / 16BIT format, so the audio quality is very high, plus the 2.4GHz frequency band, the antenna can be made very small, and Adopt PLL frequency control, add multiple frequency points for users to choose, it can be seen that it is a quite practical wireless digital audio transmission module.
The distance of this module is very suitable for digital wireless speaker system, the effect is quite good. The parameters are as follows:
