iFi Audio ZEN Air Phono External Turntable Phono Preamplifier

Theres something in the Air.Our super affordable phono stage makes your vinyl sound purer than ever.ZEN Air PhonoEnjoy a purer listening experience with the ZEN Air Phono iFi's super affordable phono stage. A phono stage also called a phono pre-amp provides the connection between the record cartridge/pickup (stylus) and the amplifier. Turntable cartridges output a very small signal. This signal needs amplifying up to several hundred times the original size before it is loud enough for your amplifier. A phono stage increases the signal level from millivolts to volts. When vinyl was the standard for audio recording the phono stage was built-in to receivers and amps allowing direct connection of a turntable. These days most receivers and amps do not contain a phono stage so a separate unit is needed. It is a necessity for any turntable without a phono stage already built-in. It will also upgrade a basic built-in phono stage in a turntable or amplifier system.Purer stillListening to music on vinyl is good for the soul. It sounds purer than listening to a track via your phone or computer. Make this experience purer still by reducing hiss noise and rumble on your records with the ZEN Air Phono.MC and MMThere are two kinds of turntable cartridges Moving Magnet and Moving Coil and the ZEN Air Phono works with both of them.The MM setting is for cartridges with an output voltage of 2mV and higherThe MC setting for outputs less than 2mVYou use the gain switch on the rear to change this setting.

With the ZEN Air Phono any warp on your records will be driven away by the 'subsonic filter'.
