On the entrance lines of the primary colours (1, 2 and 3) the video signal reaches a network consisting of three preamplifiers (4), which reinforce the adjustment of contrast control. When the signals emerge they reach another analogous network, which also constitutes three amplifiers (5) that provide added signal support in order to reach levels suitable for testing of the recomposition light (6), while the chromatic temperature is regulated as well as that of the white colour. The adoption of pre-amplifying network (4) and support (5), which run on constant power, blocks the presence of abnormal video signals and delays errors.
