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.
