Voice Compression Controller (PZA)
Environmentally-resistant voice/tone compression driver with 15-watt, 25-volt transformer
The AtlasIED VTB series models are UL-recognized, environmentally resistant speakers designed for intercom communication. VTB models feature an integral exponential horn to provide reliable sound distribution and optimal intelligibility for the reproduction of voice signals and/or electric tones. The units have a frequency response of 600 Hz to 55 kHz and are offered in six models to meet application requirements. The VTB-1 and VTB-2 series models are 8 and 4 ohm units, respectively. Models VTB-3 to VTB-6 are equipped with a built-in transformer. Termination is via 6" color-coded wire leads. Units are constructed of die-cast zinc with a water-sealed controller that will resist moisture, corrosion, vibration, insects, and vandalism. Models are available with a choice of multi-tap transformers and are designed to mount a variety of standard or custom enclosures and faceplates to meet installation and application requirements. VTB Series units will provide years of trouble-free service in stationary or mobile applications both indoors and outdoors.
