PreSonus BlueMAX - Manual (Page 16)

Stereo Operation
Your Blue Max is operating in a linked stereo mode at all times. In this mode, both signals are
used to create the gain reduction amount. This insures proper stereo imaging in stereo
compression applications. The stereo presets were optimized for two basic settings; however
all of the presets will work in stereo mode.
Manual Mode
With the Preset selector set in the Manual position, you have complete control over the
compression settings. In this mode, the threshold is fixed to –10dB. Therefore, you should
follow the same setup procedure as in the preset operating modes. Remember that if the
Ratio control is set to
1:1 (fully counter-clockwise), the compressor is basically off. A good place to start is with a
2:1 compression setting and Attack and Release in the 12 o’clock positions. You may also
want to start with one of the preset settings as described above.
