The Rosetta AD is a 24-bit analog to digital converter with all the most common digital interfaces—AES/EBU, ADAT, TDIF and S/PDIF—included as standard. The feature set of the Rosetta AD has been carefully tailored to project studio requirements. You won't pay for extensive features you'll never use. Apogee has carefully researched exactly what facilities you need and expect from an outboard A/D converter... and has delivered them in an affordable, compact, 1U rack-mount package.

The Rosetta AD features analog inputs operating at pro or consumer levels, balanced or unbalanced. The highest quality Apogee 24-bit conversion drives two AES/EBU outputs so you can feed two machines at once. In addition, ADAT, TDIF, and S/PDIF coax/optical interfaces are all built-in, for the absolute maximum in quality and flexibility!

Apogee&OOEF;s renowned Soft Limit technology allows you to record at the maximum level without overs, while our new high-resolution UV22HRù process allows you to generate flawless 16- and 20-bit masters retaining as much of the original 24-bit resolution as possible. Apogee&OOEF;s exacting analog and digital design assures top audio performance without compromise, including excellent stereo imaging and transparent sound.

The panel of the Rosetta AD is designed for quick and easy operation. Every function has its own control, clearly labeled to avoid confusion. The metering features easy-to-read bar-graph LEDs with oversize over indicators and you can determine how many consecutive digital full-scale samples constitute an over.
