There's something in the air - a super affordable phono stage that makes your vinyl sound purer than ever. ZEN Air Phono Enjoy a purer listening experience with the ZEN Air Phono, our 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 still Listening 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 MM There are two kinds of turntable cartridge – 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 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.
