behringer sonic ultramizer 110v transformer

elevenmark your transformers primary should be Black 0V Blue120V Red 230V Secondary are the yellow and orange/brown . The way I would try it, is to connect Black and Red to the 220V line. Disconnect the secondary lines for now, just in case. Then plug it in and measure the voltages on the secondary lines. If the voltages correspond to what they should be, you know how to connect it.

Looking at the way it is connect in your device, all you have to do is to substitute the Red wire for the Blue one. Disconnect your secondaries to make sure.
