The Rosetta AD's frequency
response (shown left, Fs=48 kHz)
and Total Harmonic Distortion plus
Noise (right) show the exceptional
performance of this unit. The
Rosetta AD not only out-performs
other converters in its price range:
it out-performs converters costing
many times more. This is the
Apogee tradition.
The Apogee Rosetta AD features clean, uncluttered front and rear panels. At the rear of the unit, all interfaces are easily accessible.
The analog inputs may be balanced or unbalanced, pro or consumer levels. At standard 44.1 and 48 kHz sample rates, both AES ports
are available: at 88.2 and 96 kHz both ports are used to create 2-channel path.
The Heart of Digital Audio.
