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. While I am not getting any clipping on the preamp or at the input bus I can't attain my desired headroom level of peaks at around -12dBFS unless I adjust the trim knob, at the top of the input channel of Cubase, to a setting of -9dBFS to -12dBFS. I am not sure if this is the proper use of this gain knob on cubase or if I should be looking for another resolution such as an in line attentuator on the problem mic lines. Thanks in advance for any suggestions.
