Overview
Not a plain converter box, this Universal Audio interface adds UAD DSP so preamp and channel-strip emulations run in realtime while you track. Two Unison-enabled mic preamps and a front-panel instrument input feed the processing.
Recording through emulated classic preamps, with plug-in titles from Teletronix, Pultec and UA included, is the pitch. The connection field reads oddly and input and output counts are not spelled out, which matters for planning a studio.
Who it's for
Home studio users who value the analog-style tone of emulated preamps and compressors while recording vocals and instruments. Buyers who want a simple converter, or a larger channel count, should look at other interfaces.
Pros and cons
- UAD DUO Core DSP onboard
- Unison mic preamps
- Front-panel Hi-Z instrument input
- Plug-in suite included
- Input and output counts not spelled out
- Connection field unclear
- One year warranty
Performance notes
UAD DSP runs the plug-ins on the interface itself, so tracking through preamp and compressor emulations happens in realtime with little added delay. Unison technology links the preamp hardware and the emulation. Improved converters are described as raising dynamic range and lowering distortion.
