Did the QS and SQ records for jukebox DynaQuad place content near CB so that the Hafler circuit would have something to route to the surround speakers?
They were the same as the regular album releases. There are threads here about them. The ABC "PRO" series were mini LPs. usually containing four selections from the full length "Command" LP. CBS had some mini SQ LP's as well.

The single 45 releases were less common. I have few in my Discogs want list.
