DESCRIPCION

UNICO PRE is a versatile and fine - sounding preamplifier based on hybrid valve and mosfet technology. Although designed as the natural partner for Unison Research Unico DM dual mono power amplifier, it will give excellent results with virtually any good quality power amplifier.


Circuit Design
The fully solid-state input stage uses J-Fet technology, whilst line level amplification is entrusted to three twin-triode valves. A phono stage is built-in, which is also fully solid-state using low-noise op-amps designed specially for audio use to give excellent performance on vinyl replay.
RIAA equalisation is active for the low frequency band and passive for the high frequency band.
The phono stage will cater for both MM and MC cartridges, including those with low (i.e. less than o.5mV) output.


Balanced/Unbalanced Operation
For maximum flexibility of use, five unbalanced inputs are provided, and three (line 2, 3 and 4) are also balanced. One pair of balanced outputs is also provided, as well as two pairs of normal (unbalanced) outputs. All connectors are gold plated to guarantee excellent contact surfaces throughout the life of the product.


Controls
Unico Pre is supplied complete with radiowave remote control of volume, activated by an elegant wood handset. Radio control is a convenient feature, allowing distant operation even out of sight of the preamplifier if required. The input selector is a high-quality unit, hermetically sealed with sliding gold contact surfaces for silent operation and long life. The large power on/off switch pad incorporates a soft back-lit multi-led display to provide visual indication of status.
Unico Pre is also equipped with the same Link and Loop facilities of Unico DM Power Amp, to enable remote switch-on and switch-off, activated either by musical signal or by power-on from another unit in the chain (see Unico DM characteristics for details of this feature).


Appearance Design
No Unison Research product would be complete without an attractive appearance design.
Unico Pre is no exception, its understated elegance being enhanced by machined stainless steel controls that are silky smooth in operation. Its half case - width form means that Unico Pre can be placed side-by-side with one or more Unico DM power amplifiers to give a high power yet compact stereo or multi-channel set of outstanding sonic performance.
