UNICO PRE

Předzesilovač

Unico PRE is a fully balanced amplifier with no global feedback.

Compared to the previous model of the same name, the changes are numerous and clearly noticeable, both visually and sonically.

The preamplifier’s design has been completely overhauled, following the new stylistic direction of the Unico product family officially introduced for the first time with the Unico PRE and Unico DM.

To better manage all the device's functions, a significant upgrade has been made with the adoption of a 2.4” OLED display and a next-generation microcontroller. The control interface has been simplified, allowing users to operate the unit with just two knobs (each with integrated push-buttons) and an intuitive menu system.

The amplifier stage has been entirely redesigned, preserving the strengths of the previous version while improving the architecture carefully and maintaining the sonic character without compromise.

To complete the system, a phono stage (one board per channel) has been added, along with our DAC 3 module now equipped with an expansion that increases the number of digital inputs, including one USB input, two Toslink inputs, and two S/PDIF inputs greatly enhancing the versatility of the unit.
