DetailsUnico 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. 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.
