The Unico PRE is a hybrid fully balanced preamp. All audio circuits are designed according to the "double mono" scheme. Each channel has its own pre-stage, an analog attenuator (controlled by an electric drive) and a power supply circuit. Unison Research engineers have developed original schemes for a fully balanced volume control, even for unbalanced signals, which provides the best reproduction accuracy, linearity and noise characteristics.
