Seeburg 1000
The Seeburg 1000 Background Music System is a phonograph designed and built by the Seeburg Corporation to play background music from special 16+2⁄3 RPM vinyl records in offices, restaurants, retail businesses, factories and similar locations. Seeburg provided a service similar to that of Muzak.
The Seeburg 1000 phonograph was introduced in 1959 as model BMS1. The system replaced the Seeburg Library Unit, which served the same purpose but played standard 45 rpm records. The Seeburg 1000 is enclosed in a metal cabinet 22 inches (55 cm) wide by 14 inches (35 cm) tall by 12 inches (30 cm) deep. A later version (the Seeburg Background Music Compact, model BMC1) is housed in a windowless, blue and grey painted metal box. This version contains only the record-playing mechanism, without any amplifier or timer built in.
The player is capable of playing both sides of up to 28 records and repeating the process indefinitely. The records are stacked on the spindle with the first side to be played on the bottom of the stack. A special tone arm, with two needles (one above and one below), is used to play both sides of each record. A rotating base plate below the records prevents damage to the bottom playing surface while re-stacking the records. A similar weight on top of the stack ensures stable playback of the bottom side of the topmost record.
The mechanism causes the lower portion of the spindle to rotate clockwise like an ordinary record player, while the top half of the spindle rotates counterclockwise to permit the bottom of the record to be played in the correct direction. The spindle contains three sets of retractable claws which hold the records in the upper and lower playing positions, and permit one record at a time to be dropped from the upper to the lower playing position. A release button in the top of the spindle permits the operator to retract the record-holding claws to remove the record stack.
The BMS 1000 was so called because it played both sides of 25 records, each side containing 20 songs (hence 1,000 songs). The phonographs used the old Pickering "Red-head" stereo cartridge, introduced on Seeburg jukeboxes in late 1958 for the 1959 model year. Although the mono Seeburg jukeboxes used 1 mil styluses and the stereo Seeburgs used .7 mil styluses, the background-music systems used a .5 mil stylus, but played the special mono records. The BMS phonographs were non-selectable and only played these proprietary formatted 9" records with 2" center holes - sequentially, and at 16+2⁄3rpm.
In 1963, Seeburg introduced the next generation BMS, the BMS2. Unlike the BMC1, The BMS2 was intended to be put on display. The BMS2 has a chrome trim and features a lighted window to show off the mechanism inside, similar in style to a jukebox. This phonograph has been nicknamed "the Microwave" in recent years due to its resemblance to the kitchen appliance. The BMS2 also uses a transistorized amplifier.
BMC phonographs lacking a power amplifier or internal speaker could have an optional preamplifier. Early preamps were tube-(valve-) type and (after 1963) transistorized. In 1963 the Seeburg BMCA1 "Companion Audio" speaker/4-watt amp unit became available, using both tubes and transistors. If more power or an amp was needed Seeburg had the HFA4-56, 60-watt tube (valve) amp available.
A Seeburg Background Music record is a vinyl record of a non-standard 9 inch (23 cm)-diameter size with a 2-inch (5 cm) center hole. The recording is monaural, with a playing speed of 16+2⁄3 rpm and a density of 420 grooves per inch. A 0.5 mil diamond stylus is used for reproduction. Each side contains approximately 40 minutes of music (typically 20 songs). Records in each series were numbered 1-25 from 1959 to the July 1st 1966 set, and 101-128 from the October 1st 1966 set all the way to the last set. These numbers meant nothing other than an indication as to where a record belonged in the stack order.
