Description iFi ZEN Air Phono The iFi ZEN Air Phono offers high stability and low losses for resonant circuit applications. Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels. View Owners Manual >> View Tech Lowdown >> View iFi Audio Products >> Features MC and MM There are two kinds of turntable cartridge – Moving Magnet and Moving Coil – and the iFi ZEN Air Phono works with both of them. The MM setting is for cartridges with an output voltage of 2mV and higher. The MC setting for outputs less than 2mV. You use the gain switch on the rear to change this setting. It also has a precise RIAA equalisation setting to satisfy the most demanding vinyl lover. Engage warp drive As we all know, records can become warped with age. With the ZEN Air Phono any warp on your records will be driven away by our ‘subsonic filter’. Normal subsonic filters remove ‘rumble’ AND bass and cause phase issues. Our unique AI phono sub-sonic filter removes ‘rumble’ only. OV Series operational-amplifier This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth. Panasonic ECPU capacitors Each ECPU capacitor is constructed from some 3,500 layers of ultra-thin dielectrics less than 0.5μm thickness. The iFi ZEN Air Phono offers class-leading Equivalent Series Resistance (ESR), low impedance and frequency stability and vanishingly low distortion.
