VAA-5a2l a 1RU device with video and dual audio distribution 1x5. This is the amplifier that enables the elimination of
losses and degradation in the video signal. It is characterized with: 30MHz frequency range, differential input and the
ability to equalize up to 300m (1000 feet) with Belden 8281 video cable, excellent isolation from crosstalk between
the channels which provided individual amplifiers for each audio output. The device has the possibility of installation
of transformer at the entrance. Distribution automatically adjusts for unbalanced output.
