Those who already know the Unico series will immediately notice the
new chassis and the new aluminiumcover that will be available in
natural satin
aluminium or black anodized finish according to the current aesthetic
trends. This new look has been chosen to give our products a new
appealing style and also to make themmore suitable to be integrated in
hi-fi systems whichcaninclude components from other brands.
At the same time, we are aware of how recognizable and appreciated is
the Unico-style all overthe world and we believe inthe importance
to preserve the identity of our products maintaining some winning
elements and distinctive details like the sandblastedaluminiumand
the general layout of the front panel.
Alsoin this new series, the front panels will be treated with
sandblasting and anodizing processes. The sandblasting consists in
hammering the aluminium plate with microscopic ceramic balls at room
temperature: it gives the surface a homogeneous and opaque finishing.
The successive anodizing allows the growth of a thin filmofaluminium
oxide which enhance the mechanical resistance and hardness of the
surface.
The user interface adopts a wide 12864 LCD display which dynamically
shows useful information on the reproduction status in a clear and
intuitive way. Together with the automatic brightness adjustment, in the
UnicoCD Primo the possibility to switch off the display backlight LEDs
from the remote handset has been added, so to make the presence of the
CD player even more discreet during the listening sessions.
All the player functions can be accessed through only four buttons
located in the front panel or from the remote control. Thanks to the new
software release operation is now faster andmore comfortable. Concerning the technical improvements, let us begin mentioning the
new toroidal power supply transformer: the power it can transfer, 100VA,
is large enough for a small integrated amplifierand allows future
upgrade of the audio stage.
Considering now the printed circuit board in detail, the old single
motherboard is now slip into two separated boards: one dedicated to the
power supply and digital signals circuits, the other one to the output
stage circuit.
The power supply structure follows closely that successfully used in
other models: it includes eight voltage regulators mounted on
independent heat sinks and ensure excellent control of thevoltage
levels, good efficiency and reliability.
Allthe functions of the CD player are managed by amicrocontroller
and by several other interface integrated circuits which coordinate the
data exchange between the CD drive, the LCD display, the front panel,
the IR receiver and the DAC.
The analogue to digital conversion of the S/PDIF signal has been
completelyre-designed using the best components available. It
includes a Wolfson Micro WM8804 digital receiver which controls the
incoming data and reduces the jitter, a sample rate conversion stage to
96kHz
performed by a BurrBrown SRC4192 (this DIR+SRC stage can be found in
much more expensive units) and a D/A conversion stage (Wolfson MicroWM
852424-bit DAC). In order to predispose the UnicoCD Primo to future
upgrade of the conversion circuit, the motherboard has a special socket
where different DAC boards can be inserted; asapart of amore
complex and overlookingdesign UnicoCD Primois compatible with all
the DAC board designed also for the higherlevel player UnicoCDE.
Moreover, the will to design a device as versatile as possible has
leaded also to the construction of the separate boardfor the output
stage, giving the opportunity for future replacement with newcircuits.
The current audio stage is designed around a single 12AU7/ECC82 double
triode operating in pure class A, that characterizes the sonic
performance of
the unit, followed by a discrete solid state buffer, operating in A
class too, for a low impedance output and ideal audio behaviour.
The possibilityof upgradingbothDACandaudiostageensuresthe UnicoCD Primonever to get old.
But what makes the UnicoCD Primo a new CDplayer is a digital USB input.
With the feet firmly on the tradition but glancing at the futureUnison
Research developed a player with a higher integrability but with great
sonic quality.
The USB digital input is designed to be connected with any streaming
device such as PC or laptop and accepts isochronous audio data. An auto
recognizing IC performa pure conversion od data to standard S/ PDIF
format feeding the DAC circuit. The audio information suffers no
manipulation and is handledby internal hi-fi conversion circuits thus
offering a very high quality listening experience.
The same care dedicated to the audio amplification circuitdesign has
also been reserved to the control and safety systems of the UnicoCD
Primo.
The remote controller body, one solid woodblock with a satin aluminium
cover, ensure the best comfort of use and a pleasant look.
The package, thanks to the cloth case, the stratocell elements and the
double external carton, ensuresanexcellent protectiontothe
device during shipping.
Every Unison Research product is the sum of our long experience in
designing and producing top quality high fidelity audio devices plus our
passion and ourcommitment to offer to the music lovers a chance to
live beautiful moments.
