Reply to What is wrong with this graphic EQ??

Hey guys,

Normally this stuff doesn't present a problem for me, but I've run into a situation that has me pulling my hair out looking for an answer. I am slowly building a home studio/production station, and wanted to add an old DBX 31-band graphic EQ in between my computer and my home stereo I'm using as a monitoring system right now. I have a 1/8in stereo cable going from the computer into the TRS input of the EQ with a 1/8in-1/4in headphone adapter jack on the end. It's the same situation with the output. I thought initially that maybe I had a bad cable or a bad adapter and swapped both of those out. No change. It outputs sound, but it is only outputting to the left speaker in a mono signal. Doing a stereo test confirmed that it is only recognizing one speaker. The EQ is a DBX 131 model. I'm confused as to why it's putting out a mono signal when it has TRS (stereo) inputs and outputs. What am I doing wrong? It does this on both the computer and a standard mp3 player. I'm beginning to wonder if perhaps one of the jacks on the EQ has a channel busted.
