unison research

Unison Research prides itself on creating superb sounding and beautifully made products that are praised by reviewers throughout the globe. Being expert in both single-ended valve and solid state amplification, the Unison Research range stretches from the stunning entry level Unico integrated to the lofty heights of the awesome Absolute 845 . At whatever price, the name Unison Research is synonymous with the best products hi-fi can offer to music lovers.



UNICO P £799
hybrid integrated, 50-watts

The UNICO P is the "little brother" of the blazoned UNICO. It supplies a declared power of 50W per channel, but laboratory tests has always verified a power of about 70W per channel.

It employs a preamplification tube (ECC82).

Assistance can be carried out very easily and fast thanks to the modulated realization of the power amplifiers.

Each one of the two amplifiers on its inside uses a 520gr. heatsink, and the power transformer has been created in order to allow power supply without problems durinq musical transitories.

As the UNICO, the UNICO P uses ALPS rotary potentiometer (RK27 series), and the control of volume is via infrared; it uses the same transmission and reception codes of all other units of UNICO series, and so it is possible to control the volume also with the remote controls of others apparatuses of the UNICO series.

Inside the apparatus there is a particular circuit that checks continuously the functions of the main internal parts, and the leds on the front panel indicate any anomaly found.

UNICO Line £1150
hybrid integrated, 80-watts


UNICO Line + Phono £1200
hybrid integrated, 80-watts


UNICO S.E. line
£1300
Special Edition `double` version of Unico.150 watts per channel

Hybrid Integrated Amplifier born from the UNICO amplifier.

With it we want achieve the goal of improve the nominal out-put power arriving to 130 W on 8 ohm, and improve the extension in frequency.

For achieve that we have double out-put (now we have 4 MOS-FET per channel), we have increase the capability of the filter and more power on driver stages.

This can permitted double the capability of current out-put, of the amplifier, so it can easily work at lower loud impedance value. In the same time we improve the realibility, thanks to more distribution of power consumption.

Another improvement is the placement of the power capacitors and MOS-FET they are at minimum distance.

The drivers stages were modified, we using in it a transistors circuits instead of single transistors, this improve the frequency response, the speed and linear of driver. We use the same driver used for the UNICO 200, where the problem of pilot the power MOS-FET are more.

The in-put stage is the same of the UNICO, used the double triode and a stage of communication voltage-current with bipolar transistor.

UNICO 200 £3,600
Hybrid integrated, 50/200 watts

UNICO 200 will be an integrated hybrid amplifier of more of 250W per channel, with six pairs of MOSFET per channel. The input selection is carried out with signal relays sealed in azote atmosphere and gold contacts.

It uses ALPS rotary potentiometer.

  • Input stage: 2 x twin triode ECC82
  • Output Stage: Improved dynamic class A symmetrical with power MOSFET complementary

UNICO DM £1,675
dual mono power amplifier, 150/500 watts

Unico DM is a dual-mono power amplifier using both valves and mosfets. It combines the sweetness and sonic purity of a valve input stage with a high power output stage to give complete control over any loudspeaker. Unico DM has also been designed for maximum versatility.

It can be switched to mono to give 500 watts, and can be used in a multi-unit system in which power linking and switching are taken care of automatically.

Twin triode ECC82 signal valves are used in the input stage and give to DM its convincingly natural sound quality. The output stage employs two pairs of complementary mosfets per channel to provide a generous 150 watts of power.

Balanced (XLR) and unbalanced input connectors are provided, with the possibility of simultaneous operation. In bridged mode (mono) either balanced or unbalanced inputs may be used as required.

More than one DM power amplifier and associated preamplifier may be used together, for which a power link facility is provided. This allows automatic sequential delayed switch-on of all units connected by the link.

When the DM is not operating, it remains in stand-by, ready for music activated automatic switch-on. In stand-by, power consumption is very low.

The front panel hosts an impressive power switch, back-lit by an array of multi-function leds. As well as providing smooth, uniform illumination, these leds also serve as status condition indicators. During stand-by, illumination is reduced to low level. On power-up, the intensity of illumination gradually increases; and if the protection circuit is activated for any reason the leds will initiate a warning signal by flashing repeatedly.

Unico DM is a big-hearted, versatile and fine sounding amplifier. And like all Unison Research products, it is built with pride and care to give a lifetime of musical enjoyment.
