[QuadList] Another Switcher Picture Puzzle

[Don Norwood]

Chris covered everything!  Excellent answer.

I actually thought 2 things were unusual.  The non-composite that he mentioned, and the fact that RCA used a Ball Brothers SEG in the switcher.  How often did they incorporate something from another manufacturer in their products?

Here's the first page of the catalog.

  What gave it away is the style of the mix handle.  RCA all the way.

  It is a RCA PTS-1 Switcher model 8/6D

  RCA sold this in the educational market.  They called it Professional equipment.  

  It is a Ball effects panel at the top right.

  What is unusual is that the switcher is a non-composite switcher.  The top A B buss were the mix effects that fed the wipe and key generator.  The upper right panel did the control of that buss.

  The output was fed to the MIX only buss in the center.  The delay was matched so that you could dissolve in a key or wipe.

  Lastly, the busses fed the COMPOSITE switches at the lower right.  Here would be the early quad machine or helical that was not locked to house or the network feed.  

  RCA built this from little modules that were jumped together with little cables that had phono connectors at each end.  These would fit on a 1 RU tray with three modules per tray.

    David's pic of the TE-60 reminded me of a system that I thought was interesting because of an uncharacteristic design feature for the manufacturer, and maybe a bit more difficult to identify.  It was definitely quad era, and I've seen one feeding a VR-1100.

    1) Who made this switcher
    2) What was the model number
    3) What's unusual about it
