I am trying to obtain a signal level of -20dBFS to -12dBFS at the input channel on Cubase 5, using the Focusrite Octopre Dynamic MkII mic preamp . The problem that I am having is with the recording of the drum tracks. The signal level that I am getting at the input bus is -1dBFS to -3dBFS even though my gains are set at zero on the mic preamp.
