Technical Features

Trajectum Technology

Trajectum, developed by Mola Mola, is a technology that solves the high-frequency noise and distortion issues of conventional Class D amplifiers through proprietary circuitry. The Ossetra evolves this technology further, achieving a lower noise floor and improved dynamics.

Fully Balanced Design

Employs a fully balanced configuration from input to output, enhancing immunity to external noise and contributing to improved S/N ratio.

Independent Class A Input Stage

The newly designed independent Class A input stage maintains signal purity while transmitting to the Class D output stage. This balances the sonic benefits of Class A with the efficiency of Class D.

Compact Design

Achieves 350W@8Ω output in a compact chassis weighing only 7kg and measuring 200×110×355mm. Despite being a monaural amplifier configuration, it offers placement flexibility.
