NOTE: these are the recording busses
2. Connect soundcard output jacks to the 2trk in or channel inputs to monitorback from the PC software.
3. Connect the speakers to the "CR" out of the mixer. This signal and the headphone signal are the same. To use phones only the speakers will have to be turned off . This is done on the powered speaker or power amp driving passive speakers.
