    Gain Make Up. When compressing a signal, gain reduction usually results in an overall reduction of level. The gain control allows you to restore the loss in level due to compression and readjust the volume to the pre-compression level (if desired). You can adjust the Gain Make Up from -10 to +10 | PreSonus 2007...

    What follows is an excerpt from brief tutorial on dynamics processing written by PreSonus President and Chief Technical Officer, Jim Odom. It is included to help you get the most out of your Studio Channel. This tutorial will take you through the basics of dynamics processing as well as explain the various types of dynamics processors.

    As the compression threshold is lowered, more and more of the input signal is compressed (assuming a nominal input signal level). Care must be taken not to ‘over compress’ a signal. Too much compression destroys the acoustic | PreSonus 2007...

  • Page 18 The gate range is the amount of gain reduction that the gate closes down to. Therefore, if the range is set at 0dB, there will be no change in the signal as it crosses the threshold. If the range is set to -60dB, the signal will be gated (reduced) by 60dB, etc. | PreSonus 2007...

    OPERATION 3.2.4 General Compression Setting Suggestions The following are compression presets used in the PreSonus BlueMax. We have included them as a jumping off point for setting up compression on your Studio Channel. Vocals Soft. This is an easy compression with a low ratio setting for ballads allowing a wider dynamic range.
