The Seeburg 1000 background music system was introduced in 1963 in which to provide background music or “elevator music” as we know it today for shoppers in stores, or factory workers, etc. The video incorrectly states that it is a 1959 model. These units played a special record designed by Seeburg 2″ diameter center hole 16-2/3 RPM disk. The machine was designed to provide continuous play of up to 25 disks, 20 songs per side, hence the name “1000”. At the end of the last record, the changer would lift the stack up to the top of the changer spindle for another round of playing. This would continue indefinitely until the machine would be switched off manually. This video shows the mechanical operation. Notice that there are two needles on both sides of the tonearm. The machine plays either side of the record without manually turning it over. Records were issued by Seeburg throughout the year so the same songs would not be heard over and over. When a new set of records were issued, the previous set was to be returned to Seeburg due to copyright laws. The songs are always instrumental arrangements, often by orchestras never heard of before. Unfortunately, there is no reference as to the name and orchestra of the individual songs. Some songs heard are instrumental arrangements of popular tunes with lyrics from that time the record was introduced. Records were dated as to when they were to be put in service. The record in this demo is dated for use on 12-26-64 and is an unknown “1950’s” sounding instrumental. Due to an apparent eccentric idler wheel, these units produce a lot of wow and flutter, which seems to be common for these at this age. These units were 100% solid-state when introduced. You might see the PA microphone inside the storage compartment in this video. Obviously, they played over speaker systems throughout the building and the unit itself has its own built-in monitor speaker.
