Page 8: 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. -

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 The Phonitor e makes use of analog filter networks to create the interaural level and time differences. The time difference relates to the standard stereo speaker placement of 30°. The Phonitor e offers two crossfeed settings to create the interaural level difference. -
Page 15: Crossfeed
Crossfeed Crossfeed defines the interaural level difference. The two crossfeed values approximate the influences of room size, reflection and absorption characteristics. Frequency corrected level difference at Crossfeed C1 and 30° Angle of the Frequency corrected time difference at Crossfeed C1 and 30° Angle of the right channel (red = right signal, green = left signal) right channel (red = right signal, green = left signal) µs... -
Page 16: Phonitor Matrix Presets
Phonitor Matrix presets Phonitor e The Phonitor e offers two presets. The Speaker Angle is fixed to 30°. For the Crossfeed there are two settings: C1 and C2. MATRIX Optical The value C1 has less crossfeed and therefore a lower time difference than C2. -
Page 17: Source Selection
Up to five audio sources can be connected to the Phonitor e. It features two analog stereo inputs – XLR and RCA (12). Phonitor e can be equipped with a DA converter. With that installed the available inputs are expanded by USB, coaxial and optical digital stereo inputs (13). -

Headphone outputs standard headphone output (2) takes priority over the balanced headphone output (3). There is no signal at the balanced headphone output if a headphone is already plugged into the standard headphone output. Warning: Never connect a mono jack cable to the standard headphone output (front panel stereo jack). Make sure that the stereo jack is fully inserted, otherwise a short circuit might damage the headphone amplifier! F R B... -
