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.
