Fidelix LEGGIERO MC/MM Phono equalizer

LEGGIERO is a phono equalizer that supports both MM and MC. Leggero is an Italian musical term meaning "light and graceful. This equalizer is named after its ability to handle both aggressive and aggressive expression and light and graceful expression, which is the most difficult expression for amplifiers to handle.

The MC input is equipped with Fidelix's proprietary V-I-V system. The first stage performs voltage-current conversion, and the second stage performs current-voltage conversion. This configuration provides extremely low input conversion noise of -156dBV, high input impedance of GigaΩ class, and high DC stability at the same time.

The LEGGIERO is based on RIAA, and the equalizer curve can be changed in five levels below 50Hz and five levels above 2kHz by combining the rotary switch on the left front panel and the rotary switch on the right front panel, resulting in 25 different equalizer curves, including RIAA, SP, AES, NAB, FFRR, OLD RCA, and COLUMBIA, The two switches are RIAA in the center position, so they can be used practically as tone controls with 2dB steps below 50Hz and 1dB steps above 2kHz.

A switch for switching between MM and MC is located on the rear panel, and a dip switch for switching input impedance is located on the bottom of the unit. When the input impedance is set to 1GΩ, even an iron-core MC will approach the sound of an air-core MC. When the input impedance is set to a high level, even an iron-core MC can reproduce a drifting airy sound similar to that of an air-core MC. All of the amplification circuitry is composed of JFET Class A operation, and other components include non-magnetic PRP resistors, PPS film capacitors, which offer the best sound quality available today, and no chemicon in the signal circuitry. These are the result of careful attention to the reproduction of subtle textures. In addition, the power supply for all stages operates at a nearly constant current to stabilize the power supply and prevent interference between stages through the power supply. This has resulted in both a delicate and supple expression and a powerful and clear bass.

The main unit and power supply are connected via a 6-pin DIN connector and are compatible with AC100V regions and up to AC120V regions.
