Buffer Size

The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM

data, as well as affecting system stability (see chapter 9.1). While ASIO can use any offered

buffer size, WDM is limited to 256 (XP) or 512 samples (Win 7/8). The driver handles this auto-

matically, higher settings are only applied to ASIO while WDM will stay at 256/512 internally.

Errors (USB only) does not refer to buffer errors, but USB transmission errors. The display will

be reset on any start of a playback/record. More information can be found in chapter 30.4.

WDM Devices

Allows to freely set which I/Os are available as WDM devices, if these are stereo or multi-

channel devices (up to 8 channels), and if one or multiple of the currently active WDM devices

should have the Speaker property. More details are found in chapter 7.2.

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, MADI, AES). If the selected source isn't available (No Lock), the unit will change to the

next available one (RME’s AutoSync behaviour). 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 7.4.

Output Format

AES

The channel status of the AES output signal can be set to Consumer or Professional. For fur-

ther details please refer to chapter 21.2.

MADI 1/2/3

Defines the format of the MADI output signal. MADI can be a 56 or 64 channel signal.

96 kHz

Word

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.

MADI 1/2/3

Sample rates higher than 48 kHz can be transmitted using the normal 48K Frame, or using a

native 96K Frame at the card's output.
