PHONO BOARD
Inside the
Unico Primo
there is a dedicated phono board. This
consists of two active gain stages for each channel and a 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 adjustment 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. 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.
5. FUSES
Inside the
Unico Primo
there are six fuses.:

= 1AT / 250V
F

4
= 1,6AT / 250V
F

, F
6
= 6,3AT / 250V
The value for the main fuses is:
6,3AT / 250V for 100V/120V mains voltage
3,15AT / 250V for 220V/230V/240V mains voltage
These fuses are all 5 x 20mm glass fuses. If one of these fuses
should blow we advise you to consult your Authorised Dealer or
Service Centre for advice.
