Hey All,
I have this sweet NTI EQ2 mastering eq, and it's got a bit of a problem. Each channel has an input, an unbalanced out, and a balanced out. If I used the unbalanced outs, it works like a top. If I run through the balanced outs I get super low, distorted sounding signal. Any thoughts? I unracked it to get it opened up, but don't have the screwdriver bits that I need here at home. Any ideas just from the description?
Thanks!

Dumb question of the day, what are feeding it into ? And is that balanced or unbalanced ? Also have you tried plugging it into something else?

The input isn't the problem though, it's the outs. Tried feeding in hot and cold signal, so it's not clipping on the way in or anything. No issues with other hardware in my rig either. |

It might have a transformer output and when your using the balanced out to an unproperly grounded unbalanced input!
Try plugging the balanced out on the EQ into a balanceed input.

So is it balanced or differential? Balanced simply means that both the + and - outputs are the same general impedance. Differential output would mean that there is two outputs, one of which is inverted phase.
In either case, running a transformer differential output to a single-ended input should work fine, as long as the second output signal is terminated to ground.
If the output is IC driven, it generally doesn't need the second output to be terminated to ground.
It sounds like when you use the "balanced" output, the second signal is not being terminated, therefor the transformer is not terminated.

Any ideas what I could do to fix it? I imagine pics would help? I'll see if I can get it cracked open tonight. |

If your using it unbalanced, simply use the unbalanced output. You only have a problem if the balanced out presents the same problem with a balanced input.
