VOLTAiR – 120V Rail Technology
VOLTAiR – 120V Rail Technology
VOLTAiR is the synonym for our 120V Rail Technology within the Professional Fidelity series. The audio signals are
processed with an unequalled +/-60V 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.
SPL’s 120V Rail Technology is the internal audio processing voltage (+/- 60V DC).
It is not to be confused with the external mains voltage (e.g. 115V or 230V AC).
