Overview
On a desktop, this Universal Audio interface brings dual Unison mic preamps and DUO Core DSP so plug-ins run in real time while recording. Highest-resolution audio conversion supports the signal, and the title includes the Analog Classics bundle.
Plug-in processing from names like Neve, Manley and SSL happens in hardware, so a producer hears effects as they track. The brand claims decades of use by top artists. The limitation is that the listing gives no breakdown of inputs and outputs.
Who it's for
Solo producers and songwriters building a desktop recording setup around UAD plug-ins. Anyone who wants a USB-connected box, or a documented set of connections, should check other options.

Performance notes
DUO Core DSP processes UAD plug-ins on the interface, which takes the load off the computer while recording in real time. Unison preamps are designed to pair with those plug-ins at the input stage. Conversion quality sets the ceiling for captured detail.
