GENERAL DESCRIPTION

Through proven performance, patented VT/VTF Series have earned worldwide acclaim for
service reliability. These cost-effective units offer compact size, functional flexibility, optimum
intelligibility, effective sound distribution, and high-level output. All models contain a high­efficiency compression driver with maximum acoustic conversion efficiency. (A quality which
reduces number of units needed to attain specified sound pressure levels and provides sub­stantial savings in amplification-power requirements and labor costs.) Die-cast, water-sealed
construction withstands vandalism, vermin, moisture, corrosion, and vibration during indoor
or outdoor use. Selection includes a basic 8-ohm version and 70.7 or 25-volt transformer
models with DC blocking capacitor (C) where noted. All models terminate via barrier strips.
VT Series models are surface-mount units; VTF Series are flush-mount units for recessed
installation. VT Series mounts standard 4" E.O. Boxes; VTF Series mount 4" or 4
