This is one thing I wanted to mention about the Mackie 406M that I tried this week.

I couldn't get a balanced sound when using the harmonizer. At first the highest voice was quite a bit louder. Then I fooled with the sliders and hi's and low's but nothing seemed to work. Sometimes the lower voice was to loud.

But I don't have this problem with my cheapie gear that I own and other equipment I've tried in the past.

I hope this isn't a problem with the Behringer. Has anyone here noticed this problem with other gear?
