the playback from your audio application is audible via the first output channel pair
of the ADAT output. The signal from the input is not audible at the same time,
unless the audio application provides monitoring functions which will introduce a
delay (latency) to your signal.
External Mixer
The limitation of these two options
for monitoring (which is a
limitation of many pro audiocards)
is that you cannot hear the input
and output signal at the same time.
If you use an analog (or digital)
mixer that is connected to both the
inputs and the outputs of the DSP24 ADAT card, you can monitor via the mixer so
that is no problem. The DSP24 hardware however has a built-in digital mixer so
you do not really need an external mixing desk. This function is called
External
Mixer
(easy to remember!) and as the input and playback signals, you can connect
it to
Output 1,2
as shown on the picture.
If the
External Mixer
is connected to
Output 1,2
(or alternativly to
S/PDIF Out
), all
input and all playback signals are audible simultaneously via the first two channels
of the ADAT output and the analog monitoring output (or alternativly via the
coaxial S/PDIF output). When you open the
External Mixer
(just click on the
Ext.Mixer
button under the menu), you can set the volume for each playback and
input channel independandly. This allows you to create your own mix completly
digitally inside your PC without the need of external mixing equipment and without
the need for special software from third parties. This final mix can even be digitally
resampled using the
ADSP24 (n) Digital Mixer
MME wave device or channel
11/12 of the ASIO 2.0 driver. Check the section E

Clock source selection
The three buttons in the upper left corner of
External Links
allow you to select the clock
source for the DSP24 ADAT card:
Internal
Select this (default) if the DSP24 ADAT should be the master clock
source for all operations. All digital devices connected to the
ADAT or S/PDIF output of the card need to work with external
synchronisation in this case.
