I recently found a Webcor GPG-4, Dyn-A-Phonic 4-channel matrix, with connectors on the back for four speakers, and input from the receiver. I couldn't find any information about this particular adapter online, but I'm guessing based on the name and appearance that it's probably a DynaQuad adapter/Hafler circuit?
