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.
