Ein grandioser Vollverstärker mit Kraft und sehr feiner, angenehmer Klangabstimmung.
Neu incl. Phonomodul, volle Garantie.

A perfect example of Italian style and design, the innovations
contained in the Unico integrated amplifier designs are universally
appreciated and recognized. Unico Primo is a hybrid integrated stereo amplifier capable of
delivering not less than 85W RMS continuous on a 8ohm load with both the
channels driver (as usual for UnisonResearch declared power will be
lower in order to keep our promises in every condition); with impulsive
and not correlate signals (i.e. a real musical signal) the maximum power
will be even higher.
The prototyping phase has been passed, the
“fine tuning” consisting in long hours of listening test is done. After
lots of sessions with different kind of music, different loudspeakers,
different listeners and a number of little modifications and part
selections the final release is now on the way to
production lines.
Thoughts arisen some time ago, during the design of Reference power
amplifier, induced the UnisonResearch technical staff to deeply
investigate the sonic performances of ECC83/12AX7 double triode in
particular configurations. These investigations led the designer to the
idea of using this kind of triode in Unico line instead of ECC82/12AU7.
So
we started a series of experiments on the on-production products,
taking the best of our long time experience and of the result of or
tests.
Unicoprimo shares with UnicoP a design based on a single
double triode, however in the new born amplifier the input and
preamplifier stage has been tailor suited on a ECC83/12AX7 tube (whose
characteristics are quite different from ECC82’s ones). For the driver
and power stages solutions long time tested in Unico amplifier has been
implemented even with some little improvement suggested by the
experience matured working on the following design.
Power supply has
been revised increasing power transformer and filter capacitors in order
to improve dynamics, bass response, driving capability.
Just to make
this little amp (it represents the entry level piece of Unico series) a
well equipped fighter against his competitors the design include a low
impedance active stereo output dedicated to an active subwoofer or any
other line-level input and the option to convert one of the line input
to a
phono input thanks to a easy to install RIAA preamplifier board.
The aesthetical line featuring black hairlined aluminium chassis give
the Unicoprimo a smart and
sober looking, nice finishing of the
surface and perfect proportions typical of an Italian style design. The
aluminium chassis ensures high rigidity too with improved sonic
performances and spurious vibrations dumping thanks to the three point
suspension. UnisonReasearch technical staff has put all its efforts in
this project with the ambitious aim of putting in a little amplifier all
the knowledge, all the technology and all the passion they instil in
the top level award winning devices
