VOX was a Commercial-Free XM Satellite Radio channel that specialized in classical music of the voice. It was available on channel 112 on XM and channel 865 on DirecTV. The program director for VOX was Robert Aubry Davis. XM Radio Canada added the channel to its lineup on April 1, 2007.
The channel was removed as part of XM's merger with Sirius Satellite Radio on November 12, 2008; Sirius did not have a classical vocal station, but Metropolitan Opera Radio was provided as a partial replacement. Robert Aubry Davis moved to the Symphony Hall channel, where he currently hosts a weekly Vox Choral program on Sunday mornings.
