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.
