General Description 
Every consumer wants to be free from wires, 
but system designers could never find a low-
cost, high-quality, easy-to-use wireless audio 
solution for speakers, microphones, 
headphones and headsets on the market. 
Avnera’s proprietary wireless system changes 
the game by taking a new approach to 
wireless audio. The wireless protocol was 
designed from the ground up and delivers 
uncompressed stereo audio over the air 
without interference problems. 
Avnera’s wireless modules offer a low-touch, 
easy-to-integrate wireless audio solution and 
enable fast time to market by already solving 
the problem associated with FCC, antenna 
tuning and board optimization.  
Modules based on Avnera’s AV72xx silicon 
(also known as AudioMagic 1.5G) provide 
breakthrough wireless audio functionality with 
point to multipoint transport of uncompressed 
stereo PCM audio data from a single 
AVMD7211 sender and a total of up to three 
simultaneous AVMD7212 listeners.
