Unison Research Unico Secondo

Beschrijving / Description

Stereo Integrated Amplifier (2011)

A substantial mains transformer is used and there is plenty of smoothing capacitance, plus quite extensive regulation of supply voltages for small-signal stages.

Uniquely in this group, input switching is done by a mechanical switch, mounted at the rear and operated by a long rod from the front panel volume control also uses a regular mechanical potentiometer. The latter is motorised, but input selection is not remote controllable. That means you'll have less cause to use the rather gorgeous remote, made of solid wood with a metal top plate but also less cause to lament the ugly cheesehead screws which hold it together from the top. Please change to countersunk screws, at least!

Apart from the phono stage, input provision is basic and there are no modern frills like mini-jack sockets for portable players etc. There is a preamp output, which is also applicable to bi-amping and a record output marked Monitor. The phono stage handles MM and MC cartridges, though you have to get inside and fiddle with jumpers to change settings.
