uma 75 t 2 hi z audio issue

Post by walkonatyclb » Thu Oct 16, 2014 8:50 pm

I have a uma 75t 2 amp. I have a 2 conductor wire hooked to input 3 in the hi z connection run 450 feet with a 3.5 audio plug spiced on the other end of the hi z line. It is connected to a computer music player in a green 3.5 jack.

What I want to do is put the 3.5 in a rca splitter and plug into a output of a audio switch box and hook music player to the input of the rca audio switch box. When I do so I get silence but when hooked up regular without switch box it works fine in music player. What am I doing wrong?

Sorry my friend, but that length of an unbalanced line is asking for trouble. You need to begin by provideing a balanced line with a DI (Direct Box) as the balanced source interface.

See attachment.
