FEATURES
Four Outputs
Differential Input
Battery Operated
Bandwidth 40MHz
Gain Adjust "3dB
Low Power Consumption
The PVA-50 is a portable broadcast quality video distribution amplifier which combines excellent performance with low power consumption. The unit is designed for field use, and is housed in a durable high-impact plastic case. The input is high-impedance, looping, and four 75 Ohm outputs are provided. A front panel gain control adjusts for "3dB gain. The versatility of the PVA-50 is aided by an on-board voltage regulator which allows the unit to be powered from an external AC or DC supply. Operating voltage range is identical to that of modern ENG cameras. Weighing in at only 5.5 ounces (156g), the PVA-50 can easily be carried by a field cameraman and powered by the camera's battery pack. The ability to operate from an AC supply also provides complete polarity protection for mobile or field operation.
Video performance is highlighted by an outstanding video bandwidth, within -1 dB at 40MHz, extremely low tilt, less than 0.5%, and low signal to noise ratio, greater than 60dB. Differential signal input is standard and both input and outputs are AC coupled. Phase and gain errors are controlled to within 0.25 degrees and
0.25 percent respectively. The input voltage can be AC or DC in the range of 10.8 to 20 volts with power drain of approximately 30mA. The PVA-50 is the perfect companion for practically any field operation. Performance, reliability, and economy come together in an attractive, light-weight case that won't load down the cameraman or his power supply. The PVA-50 Video DA is backed by the standard ten year warranty including parts and labor.
