Clock source
When working with digital audio signals, a clock is
always required. The settings listed here, define
where this clock comes from. If no clock is
available or a wrong clock setting is made,
playback errors or even system malfunction can be
the result.
By selecting “choose automatically” the TRACE
PRO AE driver will set up the valid clock source by itself depending on the
recording- or playback-situation. In that case, please pay attention to the
specialties dealt with in chapter “Important notes on TRACE PRO AE and
digital clock”.
Attention
: If the connected device is not synchronized with the TRACE
PRO AE and still you are recording from this digital input, the recording
will suffer digital errors. These are possibly not instantly perceptible while
quickly checking, but can ruin a recording by periodical “clicks” and
“cracks” in the long run.
Important
: The clock settings of the TRACE PRO AE manager will be
ignored and overwritten if an audio application accesses the card via the
ASIO driver. Thee settings will be done by this application. Commonly
there is a drop down list showing all available clock sources of the TRACE
PRO AE besides the field where the “ASIO TRACE PRO AE” driver is
chosen. After quitting the ASIO application the clock settings of the
TRACE PRO AE manager will be restored.
The TRACE PRO AE can be operated in 3 different clock modes. The
following section will explain these and sort the different options of clock
sources accordingly.
