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.
