New American Bright: Based on the New American Basic amp, this model
emphasizes the frequency range above 2kHz. Suitable for rock and heavy metal.
Top Class DI Warm: Famous DI box simulation, suitable for reggae and pop
recordings. Mid frequencies, in the range between 500 and 5000Hz, are de-
emphasized.
Top Class DI Deep: Based on the Top Class DI Warm, this model is suitable for funk
and fusion. The mid frequency range is strongest around 700Hz.
Top Class DI Mid: Based on the Top Class DI Warm, this model features an almost
linear frequency range, with no frequencies emphasized. It is suitable for blues, rock,
and jazz recordings.
Pre Gain slider: Set the pre-amplification level of the input signal.
Bass, Mid, and Treble sliders: Adjust the bass, mid, and treble levels.
Mid Freq slider: Set the center frequency of the mid band (between 200Hz and
3000Hz).
Output Level slider: Set the final output level for Bass Amp.
MainStage Legacy DeEsser
DeEsser is a frequency-specific compressor, designed to compress a particular frequency
band within a complex audio signal. It is used to eliminate hiss (also called sibilance) from
the signal. The advantage of using DeEsser rather than an EQ to cut high frequencies is
that it compresses the signal dynamically, rather than statically. This prevents the sound
from becoming darker when no sibilance is present in the signal. DeEsser has extremely
fast attack and release times.
When using DeEsser, you can set the frequency range being compressed (the Suppressor
frequency) independently of the frequency range being analyzed (the Detector frequency).
The two ranges can be compared in the DeEsser Detector and Suppressor frequency range
displays. The Suppressor frequency range is reduced in level for as long as the Detector
frequency threshold is exceeded.
DeEsser does not use a frequency-dividing network—a crossover utilizing lowpass and
highpass filters. Rather, it isolates and subtracts the frequency band, resulting in no
alteration of the phase curve.
