Headphone Amplier

Welcome

and thank you for purchasing the Phonitor e.

The Phonitor e is the ultimate headphone amplifier. It offers connections for headphones operated both balanced

and unbalanced. With up to . W output power the Phonitor e delivers an impressive performance.

Up to five input sources can be connected. The Phonitor e features two analog stereo inputs (XLR and RCA) and

optionally three digital audio sources (USB, coaxial, optical).

VOLTAiR technology is what we also call the SPL V Rail Technology within the Professional Fidelity series. This

makes the Phonitore an outstandig device in terms of dynamic range, signal-to-noise ratio and headroom delivering

an exceptional sound experience with invincible serenity, transparancy 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.

Max. Audio Level

Do bear in mind that dB scales do not represent linear but rather exponential increases. A dB increase corresponds

to doubling the acoustic power, +dB correspond to twice the sound pressure level, and +dB correspond 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.
