Universal Audio 2192 - Front Panel Controls; Level Meters, Clock, and Sample Rate

Clocking
The internal digital clock of the 2192 was designed for extreme stability and jitter-free operation.
The internal clock conditioner removes jitter from external sources, so conversion quality is
unaffected by clock source.
Combined with its extensive digital I/O, flexible front-panel routing controls, and phase aligned
clock conditioner, the 2192 provides high-quality master clock source and clock distribution for
your entire studio.
Two separate word clock inputs as well as AES/EBU, S/PDIF, and ADAT S-MUX can be used as
external clock sources in addition to the internal clock. Four word clock outputs are provided so
the 2192 can be used as a master clock source without daisy-chaining or cascading the clock
through external devices, which can degrade the clock signal.
A prominent lamp indicates when the 2192 is successfully synchronized to an external clock
source.
Subclock and Overclock
A/D and D/A conversion is accomplished at any available 2192 sample rate, even if the 2192
is synchronized (slaved) to an external clock source that is running at a multiple or submultiple of
the 2192 sample rate.
Subclocking occurs if the 2192 is synchronized to an external clock that is running at 2x or 4x
the 2192 sample rate. Overclocking occurs if the 2192 is synchronized to an external clock that
is running at 1/2 or 1/4 of the 2192 sample rate.
See the clocking section on page 27 for more details.
Transcoding
The 2192 can transcode (convert) digital audio between AES/EBU, S/PDIF, and ADAT S-MUX in
realtime. For example, you can transfer 192kHz audio from S/PDIF to dual-wire 192kHz
AES/EBU or ADAT S-MUX. Transcoding can be performed using any of the available clock
sources.
