The
V212
has
two,
independent,
six
output
video
distribution
amplifiers
in
a
1U
rack-mount
case.
Both
inputs
have
circuitry
to
cancel
induced
common-mode
hum
and
related
interference
to
present
a
clean
video
signal
to
six
buffered
outputs.
Both
channels
use
identical
circuitry,
so
the
two
inputs
may
be
looped
to
provide
12
identical
outputs.
Input
termination
switches
are
conveniently
located
near
the
input
and
loop
out
BNCs.
These
help
prevent
double
loading
by
either
disconnecting
loop
outputs
to
use
internal
75
Ohm
termination,
or
allowing
inputs
to
loop
through
(high
impedance).
All
video
connectors
are
BNC's
and
the
mains
supply
is
via
a
standard
three
pin
IEC
socket.
Front
panel
adjustments
are
provided
for
video
gain
and
cable
equalisation
of
both
amplifiers
and
have
enough
reserve
to
allow
compensation
for
approximately
300
metres
of
75
Ohm
video
co-ax,
or
to
tweak
up
a
poor
signal.
You
can
also
easily
switch
between
factory calibrated and user settings.
The
V212
features
robust
construction,
rock-solid
performance
and
24/7
reliability.
The
V212
is
to
be
found
in
broadcasting,
audiovisual
installations,
advertising,
sports,
corporate,
home
theatre,
security,
anywhere
a
video
signal
needs to be reliably distributed.
