Phase problem with the audiox W492
« on: December 22, 2012, 04:50:17 AM »
Hey guys,

Maybe some of you can help me.

I'm building an W492 in stereo mode, i'm using double and quad pots and have handwired them to the prints from gustav.

The low shelf, mid low and high shelf work as expected, they are all exactly the same, when ready from an RTA.

The mid-high band is where the problems come in, when set at 1kHz, the right side works as expected, the left side however is boosting at about 2kHz (with what i can see a lower Q). Also, with the mid-high band turned on, there is a phase difference of 90 degrees between left and right.

Ive worked 2 nights at the project trying to find te problem, i couldn't see or measure any difference between the left and right prints, anybody who can tell me where to search?
