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

Settings 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.
