STH-15S Description Supervised Loud Speaker The Series STH-15S supervised horn loudspeakers are equipped with a compression driver providing up to 15 Watt RMS power handling capability, superior intelligibility and dispersion to achieve maximum sound projection and penetration. The weather-resistant metal construction and the reentrant acoustic path assure protection against water, humidity, vermin, and corrosion. The mounting bracket allows directional sound dispersion via the vertical and the horizontal positioning. Provisions are also included for surface or strap mounting for the installation to pillars and I-beams. All models include a built-in 25/70/100 V transformer featuring a screw-driver adjustable, 7-position Watt/ impedance selection switch. Wiring terminals are protected with a vandal-resistant adapter cover for control equipment using a cable or a conduit. A built-in, 5 mfd capacitor is provided on both models for line supervision.
