Today Airfonix announced their AFX-19DD051 wireless transmitter for delivering wireless audio to the home theater. The two-channel transmitter with built-in Dolby Digital 5.1 surround sound and Dolby Pro-Logic II decoding delivers uncompressed, 24-bit wireless digital audio at 48-MHz transmission rate to active and passive speakers.

It features two S/PDIF coaxial/optical inputs and stereo RCA Line-in connectivity. It has three built-in 100W RMS digital amplifiers for powering front left, center and right channel speakers and a LFE channel line out for connection to an active subwoofer. The transmitter also utilizes the Airfonix Smart Channel technology, which enables the unit to search out and choose an un-congested channel in the 2.4GHz and 4.9-5.8GHz bands.

No pricing info yet, but it looks to be available in production quantities in early 2009.
