1. Presets:
Fifteen detented preset positions and Manual select.
The Presets for the Blue Max are controlled by this sixteen position rotary encoder. As the
encoder is rotated, parameters are digitally switched, simultaneously controlling attack,
release, ratio and threshold.

The Input control adjusts the gain on the input amplifiers for both channels. Amplification gain
varies widely from -20dB to +40dB. The large range is necessary to amplify instruments such
as guitar. Thus the input stage to the Blue Max is actually a pre-amp.
Note: The input control is always active, even in manual mode.

Ratio sets the compression slope. This is defined as the output level versus the input level.
For example, if you have the ratio set to 2:1, any signal levels above the threshold (note:
threshold is a preset parameter in the Blue Max) will be compressed at a compression ration
