21. Configuring the ADI-2 DAC
21.1 Settings Dialog
Configuration of the ADI-2 DAC is usually done directly at the unit. For ASIO operation sample
rate and buffer size (latency) can be set via a dedicated settings dialog. The panel 'Settings' can
be opened by clicking on the fire symbol in the Task Bar's notification area
Any changes made in the Settings dialog are applied immediately -
confirmation (e.g. by clicking on OK or exiting the dialog) is not re-
quired.
However, settings should not be changed during playback or record if it can be avoided, as this
can cause unwanted noises. Also, please note that even in 'Stop' mode, several programs keep
the recording and playback devices active, which means that any new settings might not be
applied immediately.
Buffer Size
The setting
Buffer Size
determines the latency between incoming and outgoing ASIO and WDM
data, as well as affecting system stability.
USB Diagnosis shows specific USB
transmission errors (CRC5, usually 0)
and general errors. If the unit detects a
record or playback error the number
shown will no longer be 0. An audio
reset is performed automatically. The
counter
is reset on start of
playback/record.
Sample Rate
Sets the currently used sample rate.
Offers a central and comfortable way of
configuring the sample rate of all WDM
devices to the same value, as since
Vista the audio software is no longer
allowed to set the sample rate.
However, an ASIO program can still set
the sample rate.
During record/playback the selection is greyed out, so no change is possible.
The tab
About includes information about the current driver and firmware version plus two more
options:
Lock Registry
Default: off. Checking this option brings up a dialog to enter a password. Changes in the Set-
tings dialog are no longer written to the registry. As the settings are always loaded from the
registry when starting the computer, this method provides an easy way to define an initial state
for the ADI-2 DAC.
Enable MMCSS for ASIO activates support with higher priority for the ASIO driver. Note: At this
time, activating this option seems to be useful only with the latest Cubase/Nuendo at higher
load. With other software this option can decrease performance. The change becomes active
after an ASIO reset. Therefore it is easy to quickly check which setting works better.
