About the iFi Audio micro iPhono2
Big performance in a small package
Big performance in a small package
How can such a sophisticated phono preamp fit in such a small package? I admit I don't know how iFi did it, but the vinyl junkie in me is sure glad the micro iPhono2 exists. It's compatible with a variety of moving magnet and moving coil cartridges, and it lets you select one of three EQ curves to boost signal and reduce noise. And it weighs less than 10 ounces and can hide away just about anywhere.
Micro switches on the bottom of the iPhono2 offer precise control of cartridge loading and EQ settings.
The iPhono2 offers three selectable EQ curves, based on iFi's deep knowledge of how legendary studios record their albums. The Columbia and Decca EQ curves are customized to make records issued before 1980 sound their best. Post-1980 recordings are optimized by the RIAA curve, which has four very specific sub-settings that help audiophiles find the perfect match.
- Class A TubeState® phono preamplifier
- three-position switch for choosing basic EQ settings settings (Columbia, RIAA, and Decca)
- 24 micro switches on underside for selecting cartridge loading and refining EQ
- stereo RCA input for moving magnet cartridges
- stereo RCA input for moving coil cartridges
- stereo RCA output

More details on the iFi Audio micro iPhono2
Overview: The iFi Audio micro iPhono2 is a compact, Class A TubeState phono preamplifier that brings out the best in your vinyl recordings. With separate inputs for Moving Magnet (MM) and Moving Coil (MC) cartridges, micro iPhono2 amplifies the signal, but not the noise. It offers multiple gain, load, and EQ curve options to make your turntable sound as good as possible.
MM/MC Inputs: Separate inputs are provided for MM and MC cartridges. The output voltage of the cartridge determines which input you should choose. Cartridges with an output less than 1.2mV should be connected to the MC input, while those equal to or greater than 1.2mV should be connected to the MM input. MM and MC inputs should not be connected simultaneously. A ground wire extension is included for connecting the turntable's ground wire.
Gain Setting: After connecting the turntable to the appropriate input, you should determine and set the gain. The micro iPhono2 offers gain levels from 36dB (63 times) to 72dB (4000 times) for cartridges with rated outputs from 0.1mV to 10mV. The required gain is determined by the cartridge output. On the bottom of the unit are three sets of micro-switches that need to be set according the the settings below:
|Cartridge Output||Gain Required||Input & Switch Settings|
|1.2mV - 4.8mV||48dB||MM & +12dB|
|0.3mV - 1.2mV||60dB||MC|
|<0.3mV||72dB||MC & +12dB|
Load Setting: Every cartridge requires a load in order to sound its best. In many cases, the correct load value is stated in the cartridge manual. In other cases, you will need to determine an appropriate load value by listening for the setting that sounds the most natural. The micro-switches on the bottom panel are used for setting the correct load. A card with suggested gain and load values is included.
EQ Curve Selection: The micro iPhono2 is equipped with a 3-way switch on the front panel for selecting the EQ curve. Between 1954 and 1980, record labels slowly adopted a standard RIAA (Recording Industry Association of America) EQ curve. If you're playing a pre-1980 record, it's possible that it was manufactured using a different EQ curve. The EQ curve switch lets you choose between the RIAA EQ curve, or the Columbia or Decca EQ curve. It is suggested that you first listen with the RIAA EQ curve, then try the Decca or Columbia EQ to see which one delivers a truer sound. You can also fine tune the RIAA EQ curve using the micro-switches on the bottom of the unit. Choices include eRIAA (enhanced), RIAA, IEC, or eRIAA+IEC.
