Phonos is a preamplifier for record players using either moving magnet (MM) or moving coil (MC) cartridges. The equalization curve is according to RIAA and suitable for all vinyl records since 1954. With up to 71.5 dB gain for MC cartridges and 50 dB gain for MM cartridges Phonos belongs to the most powerful phono preamplifiers. VOLTAiR technology is what we also call the SPL 120V Rail Technology within the Professional Fidelity series. This makes the Phonos an outstandig device in terms of dynamic range, signal-to-noise ratio and maximum headroom delivering an exceptional sound experience with invincible serenity, transparancy and realness.

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.

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. 0 20 40 60 80 100 120 Volt 30 V 36 V 120 V + / - 15 Volt + / - 18 Volt + / - 60 Volt Operating Voltage 120 125 130 135 140 145 dBu 124,2 129,1 141,4 OPA 134@30 V OPA 134@36 V SPL-OP@120 V Max.

Do bear in mind that dB scales do not represent linear but rather exponential increases. A 3 dB increase corre- sponds to doubling the acoustic power, +6 dB correspond to twice the sound pressure level, and +10 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 10 dB higher. THD measurements show a difference of more than 3 dB compared to the OPA134 at 36V — in terms of sound pres- sure level, that corresponds to an improvement of more than 50%. The operating level most commonly used for audio equipment is +/- 15 volts.

• Choose the right setting regarding your cartridge with the Cartridge Switch (3). Capacity (MM) Choose the right setting regarding the capacity of your MM cartridge with the CAPACITANCE switch (4). If you do not know the right setting for your record player, start with capacity = OFF. If you increase the value you will receive a higher tone. Impedance (MC) Choose the impedance for your MC cartridge with the IMPEDANCE switch (5). If you do not know the right setting for your record player, start with an impedance of 100 ohms. If you increase the value you will receive a higher tone.
