The Simplex SH-1000, also called the Simplex Four Star, is a direct drive soundhead originally introduced with the E-7 line of projectors in the 1930s. It was replaced by the X-L series soundheads, which are very similar to the SH-1000 but have a compartment below the exciter lamp to house a preamp. The SH-1000 remained popular long after the introduction of Simplex's belt-driven soundheads, which are generally considered inferior to the earlier direct drive models.

When threading the SH-1000 pull the film taught around the sound drum, then back it off from the upper soundhead sprocket by two perforations. There should be eight perforations of slack between the upper and lower soundhead sprockets.
