I have a problem with all stereo channels. While using them as stereo pairs, there's always lower volume on right channel.
I have linked them, otherwise 9/10 would only work as a mono channel, using left input only, right?
Since this occur on all stereo channles, it might be something I overlooked.
If I plug my stereo output from source using channel 1 and 2 or 3 and 4, it's all fine.
