The Simplex SH-1000, also called the Simplex Four Star, is a direct drive soundhead originally introduced with the [[Simplex E-7|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.
