I tried it and it worked. I mean, I can hear the preamp now. Now, there's still a problem because the waveform does not look like a DI signal, looks almost the same as my line-recorded preamp signal. And I want to use this DI Box to be able to edit easier. I set up two tracks to record, one with send 1 and the other with send 3. But they both seem to be wet and they are the same visually, not good.
