DESCRIPTION:

Unico DM is a dual- mono hybrid power amplifier designed to work both in stereo and in mono mode. The massive and well proportioned looks reflect an accurate internal layout developed around two impressive toroidal power transformers and over-sized heatsinks.

Compared with the previous models from Unison Research, the technical staff increased the number of output devices, the dimensions of the heatsinks (now placed inside the chassis for a cleaner look) and the power handled by the power transformers. The internal layout has been completely revisited and improved with great care to the signal path, the grounding layout, and the high current output connections.

Input connection is available both via XLR and RCA plugs. These are two really independent inputs and can be selected using a front panel push button. Selection is operated by a sealed micro relay placed near the connectors for the shortest signal path. The tube preamplifier stage is also located nearby.

An accurate project allowed the designers to place the power stage and dedicated power supply very close to the output binding posts. This is an essential feature when you manage to run the device in mono mode delivering over 650W on 8 ohm without the problem that such a high current can cause on a poor designed circuit.
