Descrizione

The 2192 Master Digital Audio Interface is the first product to combine Universal Audio’s long history of creating high-quality, vintage analog gear with its advanced digital technology. While features like sample rates up to 192K, realtime transcoding between AES/EBU, S/PDIF and ADAT, and support for single and dual wire AES modes are sure to impress, what really sets the 2192 apart is its Class-A analog circuitry, which provides luscious detail and clarity, while retaining the warmth and character of the original source, features typically not found in digital units.

The soul of the 2192 is the analog circuitry used in the A/D and D/A converters.

The 2192 serves as an extremely high-quality digital to analog and analog to digital converter. If, for example, you’re working on a digital console, or workstation, that utilizes higher sample rates, the 2192 can dramatically improve your monitoring environment and/or the quality of your analog masters. As a front end for a native workstation, the 2192 provides two channels of sterling sound quality for tracking, monitoring and mastering.

The 2192 also offers tremendous flexibility in signal routing and monitoring. You can, for example, run signal into the analog inputs, at samples rate ranging from 44.1K to 192K, and simultaneously output it to AES/EBU (single- or dual-wire), S/PDIF and ADAT (with industry standard S-MUX interleaving for sample rates above 48kHz). The selectable output monitor allows you to monitor any of the digital inputs, or the analog input with no interruption of the transcoding.

Now you don’t have to choose between advanced digital features and old world analog quality, the 2192 delivers both.
