Here are two views of NXA --- the UPI Audio network HQ in the Daily News Buiding, shot around 1973 or 74.

They show the combination newsrooom/production area and a closeup of the main feed transmission console ... an Altec Lansing, put into service around the time of UPI's acquisition of ex-competitor Radio Press International in 1966. A similar console, that had been used at RPI, was later used for UPI's newscasts, which were added to the Audio service about five years later.
