The 3xATT module is a passive attenuator with LIN(ear) or LOG(arithmic) mode selection, offering three independent sections.
Section 1 proposes a LIN(air) attenuator.
Sections 2 & 3 offer the choice of LIN/LOG modes thanks to a selector (with short axis so as not to interfere with the manipulation of the potentiometers):– LIN(eary) for logic signals or– LOG(arithmic) for AUDIO signals.
Accepts all signals (logic = LIN or audio = LOG).
What’s the difference between a lin and log pot and why we utilise this:Linear:The resistance of this type of potentiometer varies linearly, that is to say that the value of its resistance increases (or decreases) proportionally when moving the cursor. It is used, for example in a variable voltage source. Ideal for logic signals, CV, LFO etc …Logarithmic:The resistance of this type of potentiometer varies exponentially, that is to say that the value of its resistance increases (or decreases) more and more rapidly when the cursor is moved. Ideal for AUDIO sources, for sound volume adjustments, to adapt to the characteristic of the human ear, which has a logarithmic response to the pressure that the air exerts on the eardrums.
