TX-AUDIO-24/AE  Evaluation Board

 

The TX-AUDIO-24/AE-D and RX-AUDIO-24-D demo boards may be used “as is” to set up a high quality 
wireless digital audio link for applications such home theatre systems, audio media center, wireless 
headphones, etc… 
Each demo board includes an RF module ready to plug in. All that is required to set up the wireless au-
dio link is a suitable line level audio source and a DC power supply for the transmitter, and an audio am-
plifier and a DC power supply for the receiver.
