More specifically those using it with an interface such as the mbox 2 with unbalanced outputs. This is a long post so you can skip to the fix if you want to.
I bought my x-amp about 2 years ago and have only used it a few times because the output signal was always very low. I would turn the gain all the way up on the mbox 2 output and it would distort it. Needless to say I stuck it in a box and forgot about it. Until the other day.....
The user's manual for the mbox 2 says the mbox has balanced outputs so i used a 1/4" trs to xlr adapter to xlr cable to connect the two units as I had been doing before. I had the same results as before. I decided to start poking around online to see if i could find a fix for it. I found nothing except other people having the same problem and that all the big retail sites (such as american musical, musiciain's friend, zzounds, etc.) listed the mbox 2 as having unbalanced outputs.
So I decided to modify the adapter I had that was originally 1/4" TRS to XLR, and make it a 1/4" TS to XLR. It worked great. The x-amp worked like it was supposed to.
Here is how I fixed it:
There are three wires inside the adapter. (this will work if your making a TS to XLR cable as well)The are listed as follows.
TRS
Red (hot) - Tip
Blue/Green (cold) - Ring
Black (ground) - Sleeve
XLR
Pin 1 - Ground
Pin 2 - Hot
Pin 3 - Cold
Connect them as follows:
TRS red - XLR pin 2
TRS black - XLR pin 1
TRS blue - Remove completly from TRS (This is not used)
Jump Pin 3 to pin 1 on the XLR.
Your TRS adapter/cable has now become a TS to XLR unbalanced adapter.
Sorry for the long post. I just though this might help someone else who is scouring the site for a fix to the problem.
