Among the many features of the IN3264 and IN3268 Distribution Amplifiers is the ability to not only
have 1 x 4 or 1 x 8 configurations (respectively), but, by unterminating the input impedance, users can add
a loop-out to other DAs as well. This effectively converts the IN3264 into a 1 x 5 DA, and the IN3268 into
a 1 x 9.

The IN3264 is equipped with three sets of jumper pins per color (three for red, three for blue and three
for green) for a total of 9 individual jumpers (see Diagram 1-1). Each one has a specific purpose. The
factory default setup has all jumper pins closed except for J9, J11 and J13. These jumper pins are there to
be used in the event that another board is added, converting the DA into a 1 x 8, resulting in the IN3268.
These pins should remain open at all times.
