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.
