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. -

Page 11: Phonitor Matrix
Phonitor Matrix Basics of stereo listening When listening to speakers sound coming from the right is not only perceived with the right ear (red line) but it is also perceived with the left ear (green line). The sensation is time delayed, lower in level and has a reduced fre- quency range (this applies to the left speaker accordingly). -
Page 12: Stereo Listening With An "Traditional" Headphone Preamplifier
Our brain determines the direction of the sound by perceiving the time delay (interaural time difference) and the level difference (interaural level difference). Stereo listening with an “traditional“ headphone preamplifier When listening to music with a traditional headphone amplifier, the right ear only perceives the right signal (red line) and the left ear only perceives the left signal (green line). -
Page 13: How Does The Phonitor Matrix Work
How does the Phonitor Matrix work? In simple terms, the Phonitor Matrix creates a speaker-like listening experience on headphones. It calculates the time and level differences with their specific frequency responses to deliver a true rendition of a speaker playback. Because time and level differences are set like real loudspeaker place- ment, the brain is able to correctly identify the direction of the sound. -
Page 14: Angle
In Detail An analog filter design creates interaural time and level differences for four different speaker placements. This analog filter design is controlled by the crossfeed and angle parameters. Angle With the ANGLE switch you adjust the interaural time difference which is related to the placement of the speakers. -
Page 15: Crossfeed
Crossfeed Crossfeed defines the interaural level difference. The six crossfeed values approximate the influences of room size, reflection and absorption characteristics. Frequency corrected time difference at max. Crossfeed and 30° Angle of Frequency corrected level difference at max.

Page 16: Setting Of Parameters Crossfeed And Angle
A vast number of factors, e.g. type of loudspeakers, room acoustics or the individual perception, influence the ste- reo-listening. This is why the Phonitor x offers six different switch positions to finely adjust the Crossfeed and to best match to your speaker playback. - Page 17 Table: Settings of Crossfeed and Angle Angle parameter Crossfeed parameter Interaural level difference Interaural time difference (µs) Speaker angle 0,24 15° 0,35 20° 0,40 20° 22° 0,47 25° 0,50 25° 0,60 30° 0,40 20° 0,49 25° 0,56 30° 30° 0,64 30°...

Page 22: Mode Switch
MODE maintains the same loudness, because both stereo channels are each reduced by 6 dB. Laterality Phonitor x Laterality refers to the deviation of sound perception to either side of the ears. With the Laterality control (6) can compensate perceived volume differences between channels that may be due to a hearing impairment. -
Page 23: Vu Meters
The meter indicates levels from -20 dB to +5 dB. 0 dB corresponds to +4 dBu. If necessary you can lower the sensitivity by 10 dB so that the meters go up Phonitor x to +15 dB intput level (see ”DIP switches“ on page 26). -
