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.
