Electric synchronizer `` SEL-1 ''.

Service devices.The SEL-1 electric synchronizer has been produced presumably since 1970 at LOMO. The device is used to synchronize the speeds of motion picture and magnetic tape when playing soundtrack. It is an attachment to a tape recorder and works in conjunction with an 8-mm amateur movie projector "Luch" or "Rus" and any reel-to-reel tape recorder that provides a magnetic tape speed of 19 cm / s or 9.5 cm / s and the ability to remove a loop of tape for the limits of the tape recorder.
