Welcome
and thank you for choosing the Performer s.
The Performer s amplifier is an ultra-compact power amplifier that delivers  x  W to  ohms loudspeak-
ers. In bridge mode it delivers  W into  ohms.
VOLTAiR technology is what we also call the SPL V Rail Technology within the Professional Fidelity series. This
makes the Performer s an outstandig device in terms of dynamic range, signal-to-noise ratio and headroom
delivering an exceptional sound experience with invincible serenity, transparency and realness.

VOLTAiR – V Rail Technology
VOLTAiR is the synonym for our V Rail Technology within the Professional Fidelity series. The audio signals are
processed with an unequalled +/-V DC, which corresponds to twice that of discrete operational amplifiers and
four-times that of semiconductor operational amplifiers.
VOLTAiR Technology reaches outstanding technical and sonic performances. Technically especially in terms of
dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally
relaxed sounding audio experience. Music sounds absolutely natural.

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.

Do bear in mind that dB scales do not represent linear but rather exponential increases. A dB increase corre-
sponds to doubling the acoustic power, +dB correspond to twice the sound pressure level, and +dB corre-
spond to twice the perceived loudness.
When it comes to volume, the VOLTAiR Technology exhibits a performance, in regard to maximum level and dynamic
range, that is twice that of common components and circuits given that its values are approximately dB higher.
THD measurements show a difference of more than dB compared to the OPA at V — in terms of sound
pressure level, that corresponds to an improvement of more than %. The operating level most commonly used for
audio equipment is +/-  volts.
