Certain situations may require that these inputs be unterminated (e.g., multiple inputs driven from a single output). This can easily be accomplished by moving jumper J12 to the unterminated position (move jumper towards the front of unit). 3.4.2 Analog Audio Input Termination J13/J14 [10k ohms] If you are using equipment designed to
