Clock Mode

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

by itself.

During record/playback the selection is greyed out, so no change is possible.

Clock Source

The unit can be configured to use its own clock (Internal = Master), or one of the input signals

(Word, Sync In, AES, TCO). If the selected source isn't available (Input Status No Lock), the

unit will change to the next available one (this behaviour is called AutoSync). If none is available

then the internal clock is used. The current clock source is displayed as Current.

Pitch

More information on Pitch is available in chapter 11.2.

Options

TMS activates the transmission of Channel Status data and Track Marker information from the

AES/EBU input signal.

Word Clock Out

The word clock output signal usually equals the current sample rate. Selecting Single Speed

causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz and

192 kHz sample rate, the output word clock is 48 kHz.

Output Format

Double Speed: Sample rates in the range of 64 kHz to 96 kHz can also be transmitted using the

standard 48K frame. Note that when selecting Double Wire the number of output channels is

reduced to 8.

Quad Speed: Sample rates in the range of 128 kHz to 192 kHz can also be transmitted using

either the standard 48K frame, or the 96K frame. Note that when selecting Double Wire the

number of output channels is reduced to 8. When selecting Quad Wire the number of remaining

output channels is 4.

For further details about the settings Professional, Emphasis and Non-Audio, please refer to

chapter 23.2.

Input Status

SyncCheck indicates whether there is a valid signal (Lock) for the inputs Word Clock, AES 1 to

8, TCO and Sync In, or if there is a valid and synchronous signal (Sync). Each input has its own

frequency measurement and display of the input signal's current sample rate.

The tab About includes two more, global 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

of the HDSP AES-32.

Optimize Multi-client Mixing

Default: on. Unchecking this option might solve compatibility problems in seldom cases, but will

also introduce short noise burst when multi-client playback starts.
