Comparisons

These diagrams show how our VOLTAiR Technology compares to other circuits.
The direct relation between operating level and maximum level is fundamental for the classification: the higher
the operating level, the higher the maximum level a circuit can handle. And since virtually all essential acoustic
and musical parameters depend on this relation, a higher operating voltage also has a positive impact on the
dynamic range, distortion limit and signal-to-noise ratio.
