8.1) User settings: Attenuversion

1) OVERVIEW

Attenuversion combines 'Attenuation' – the control of an input signal's volume – and 'Inversion'

– a reversal in the polarity of an Alternating Current (AC) waveform.

This user setting converts the functionality of a normal volume knob that controls the attenuation

of a single, non-inverted, waveform where fully counter-clockwise (fully left) outputs silence

(100% attenuation) and fully clockwise (fully right) outputs maximum volume – to one that controls

the attenuation of both a non-inverted and an inverted version of the waveform.

When this setting is activated the knob rotation starts at fully counter-clockwise with the inverted

version of the input signal output at full volume, then, as the knob rotates clockwise, it decreases

the volume of the inverted version of the input signal to silence (100% attenuation) once it reaches

the 12 o'clock (middle) position.

As the knob continues to rotate past 12 o'clock it starts to increase the volume of the non-inverted

version of the input signal, reaching maximum volume at the fully clockwise position.

The Attenuversion user setting is activated via the 3-pin header on the rear PCB that is marked 'Ax'

where 'x' is the channel number e.g. the header marked A1 is the Attenversion header for channel 1.
