The Creme is equipped with two broadband equalizer bands.
The filter circuit was taken from the Classic Equalizer EQP-1.
Parameters not so relevant for the master bus were set to a fixed
value of 0. And the control range was limited to a value that
makes sense for the mix bus.
Rotary controls have been replaced by rotary switches so that
the values can be easily restored.
Both EQs are shelf equalizers.
A shelf equalizer, often referred to as shelving EQ, is a type of
equalizer that boosts or cuts the frequencies above or below a
certain point. A shelving EQ can be either a high shelf or a low
shelf.
A high shelf will boost or cut all frequencies above a certain
point, and a low shelf will boost or cut all frequencies below a
certain point. The point at which the boost or cut begins is
typically adjustable, and is referred to as the 'shelf frequency' or
'cutoff frequency'.
The term "broadband" in this context likely refers to the fact that
a shelving EQ affects a broad range of frequencies, either all
frequencies above or below the shelf frequency, rather than just
a narrow band of frequencies as with a peaking or band-pass EQ.
Shelving EQs are commonly used for broad tonal balance
adjustments in mixing and mastering. They are less precise than
peaking EQs, but are often more musically pleasing for wide-
ranging tonal changes.
