1630 KCJJ (((AM-Stereo))) "Quadraphonic Broadcast" Robb Spewak Show - Feb. 26, 2010 - Бесплатная аудиокнига

These are the complete "podcast" recordings of the believed to be first ever program broadcast in 4-channel quadraphonic on analog AM radio. This broadcast was made on February 26, 2010 by the "Mighty 1630" KCJJ in Coralville, Iowa, engineered by Tab Patterson, and hosted by Robb Spewak.

This was achieved by encoding discrete quadraphonic material (quad 8-track tapes, DVD releases, etc...) with Dolby Pro Logic II. The resulting two-channel stereo program encoded with Dolby Pro Logic II was then transmitted using C-QUAM AM-stereo. Listeners who owned AM-stereo radio receivers could feed this stereo broadcast into a Dolby Pro Logic II decoder, such as a home theater system, to hear four discrete channels.

Since listeners using AM-stereo receivers, especially ones that could be connected to a Dolby Pro Logic II decoder, are few and far between in 2010, the broadcast was also steamed online and made available to download on Robb Spewak's website. As of uploading this, the website has since appeared to have been taken down.

Here's the archive of the original site posting.

KCJJ has since discontinued broadcasting in C-QUAM AM-stereo over disputed claims that it affected their coverage area.
