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 200 £4995
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 £3250
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.
