    Is the phono stage MC?

    From the manual:
    THE PHONO BOARD
    Inside the Unico Secondo there is a dedicated phono board. This
    consists of two active gain stages for each channel and an RIAA
    equalisation stage which is active for the low frequencies and passive for the
    high frequencies. This solution is the result of extensive listening tests, and
    provides an excellent combination of deep, well-controlled bass and clear,
    sweet treble.
    This phono board is able to interface with both MM and MC
    cartridges.
    Movable links on the board (two for right channel and two for left
    channel) enable this adjustement to be carried out. The relative positions are
    clearly marked MM and MC.
    Two further movable links fitted to the Phono Board allow the
    level of gain (amplification) to be changed by +/-10dB. These links are
    marked JP102 and JP103. In practice, MM cartridges having an output
    lower than 4mV and MC cartridges having an output lower that 0.5mV will
    probably require these links to be set at the +10dB position.
    Specifications - Phono Board
    MC :
    • Gain: 50-60dB
    • Input Impedance: 100Ohm // 440pF
    MM :
    • Gain: 40-50dB
    • Input Impedance: 47kOhm // 220pF
    THD: < 0,1%
    RIAA: active/passive
    RIAA tolerance: ± 0,1dB
