Gain problem

I’m in the middle of learning and create the show and scenes for the T112 and idr32 which we purchased for our church.

I love the t112 and I’m happy that we switch in the “very last second” from the ls9 to iLive!

I have a “problem” with the gain encoder on the surface,

If i adjust the gain i got a crunching sound like a old oxidized pot. plainly audible between 20 -65 db

It doesn’t matter if i use the gain knob in the gain section, or the encoder under the display

This effect…

i don’t have if the source is on the surface, only on the idr32 connectet sources

i don’t have if use the trim instead the gain encoder

i also have if i adjust the gain in the iLive-Editor

work as designed or bug?

Firmware 1.51

…sorry my bad english…
