An interesting photo today on Facebook from Stephen Marsh Mastering titled "Running Quads".
It shows a 4 Channel Analog Tape Machine playing a well known Quad Recording from the 1970's being prepared for Multichannel SACD release by Audio Fidelity!
Have a look at the Facebook photo and comments.....
