Atlas Sound VTB series models are environment-resistant loudspeakers designed for intercom communication. VTB Models feature an integral exponential horn to provide reliable sound distribution and optimum intelligibility for the reproduction of voice and/or electric tone signals. Units have a frequency response of 600Hz to 55kHz, and are offered in six models to meet application requirements. Series Models VTB-1 and VTB-2 are 8 and 4 ohm units, respectively. Models VTB-3 through VTB-6 are equipped with a built-in transformer. Termination is via 6" color coded leads. Units are of die-cast zinc construction with a water-sealed driver that will withstand moisture, corrosion, vibration, vermin, and vandalism. Models are available with a selection of multi-tap transformers and are designed to mount a variety of standard or custom housings and face plates to meet installation and application requirements. VTB Series units provide years of trouble-free service in stationary or mobile applications both indoors or outdoors.
