You were probably using the old Dolby single channel units (385's?).  They
were basically a card cage with a Cat 22 card stuck in them.  They supplied
the power, trim pots and a bypass switch to the Cat 22. You would have to
have had 16 of these beasts for your system (ouch).  I would guess if you
still had them in the late 1980's early 1990's, you could have plugged in
the Cat 280's for much better sound.
