FOR SALE: Unico DM Amplifiers (3 Units Available)
Unico DM is a dual- mono hybrid power amplifier designed to work both in stereo and in mono mode. The massive and well proportionate looking reflect an accurate internal layout developed around the impressive couple of thoroidal power transformers and the over-sized heatsinks; the clear but not empty, agreeable but not ostentatious face seems well appropriate for a “simple” power amplifier, reliable, complete and generous.
Compared with the previous model UnisonResearch technical staff increased the number of output devices, the dimensions of the heatsinks (now placed inside the chassis for a nice looking) and the power handled by the power transformers. The internal layout has been completely revisited and improved with great care at the signal path, at the grounding layout, at the high current output connections.
Input connection is available both via XLR and RCA plugs, these are two really independent input and can be selected using a front panel push button. Selection is operated by a sealed micro relay placed near the connectors for the shorter signal path, tube preamplifier stage is nearby too.
An accurate project allowed the designers to place the power stage and dedicated power supply very close to the output binding post. 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.
