serial digital video distribution amplifier restores the incoming signal to its proper amplitude. The signal is reshaped with automatic equalization, re-sliced and DC restored. Six outputs are provided on the rear panel. A module fault LED on the front panel of the unit indicates that the input signal level is below a preset threshold. It accepts composite 143Mbps and 177Mbps, component 270Mbps, and 16:9 aspect ratio 360Mbps standards. The signal is transparent to the incoming signal data rate. The output level is adjustable from the front panel. The 500 series products are compact designed for portable operation or fixed studio use. Any 500 series along with the 700 series will operate in the PRT-700 mounting frame.
