VDA-640 (# 100-0-021): The VDA-640 is a six-output loop-thru input, video distribution amplifier with gain. The
loop-thru input allows the original signal to go through unimpeded to other equipment while still allowing other channels
with gain control to split up the signal for processing or monitoring. If the loop-thru connector is not connected, a
75 Ohm termination must be present for the VDA-640 to work properly. Each channel has 0.5X to 2.0X of adjustable
gain. 75 Ohm terminators are available for purchase.
