PRELIMINARY DATA SHEET
16-channel 96 kHz A/D with ADAT and
S/MUX, Dual Reclocking, UV22HR & SoftLimit
Apogee Quality – Application-focused architecture
Apogee's new AD-16 is a 16-channel 24-bit A/D converter,
operating at sample rates up to 96 kHz. The system offers
ADAT optical output for compatibility with a wide range of
digital audio systems, and can sync to word clock (using the
same powerful 2-stage reclocking system utilized in the
DA-16 "IntelliDAC"), or its own internal high-stability clock.
Word Clock output is also provided.
For the first time in an Apogee A/D conversion system, the
AD-16 supports the Sonorus S/MUX specification for sam-
ple-splitting of high sample-rate audio data into multiple
ADAT-style optical interfaces. Additional light-pipe outputs
are provided to deliver up to 96 kHz digital audio from all
16 channels in this mode. A special port is also provided for
future expansion.
An LED indicates signal status on each channel, with the
intensity modulated by the signal level to give an "analog-
like" display. A second LED per channel indicates "overs".
The balanced analog inputs are configured in two groups

The AD-16 includes Apogee's industry-standard word-
length reduction system, UV22HR, for reducing the word
length from the native 24 bits to 16 for CD mastering,
Internet audio and other applications, and SoftLimit to
maximize digital output level without overs. The features
are activated with a pair of buttons, and may be optionally
applied to channels 1–8, 9–16 or all. The AD-16 features an
elegant and effective user interface, including a power
switch, sample rate/sync selector, clear "overs" button,
and two buttons for Soft Limit and UV22HR respectively,
and closely matches the companion DA-16 16-channel D/A
in appearance.
With the AD-16, like the DA-16, Apogee offers an applica-
tion-focused architecture with the features you really need.
Without sacrificing quality, these products make high-quali-
ty conversion more accessible, and more available to a
wider range of creative people.
