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). If the selected source isn't available (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 
MADI In 
Defines the input for the MADI signal. 'Optical' relates to the optical input, 'Coaxial' to the BNC 
socket. 
TMS activates the transmission of Channel Status data and Track Marker information from the 
MADI input signal. 
Auto activates redundancy operation. If the current input signal fails, the other input will be used 
immediately, provided a valid signal is found there. Input also works as automatic input selec-
tion, in case only optical or coaxial is present as input signal. 
MADI Out 
Defines the format of the MADI output signal. MADI can be a 56 or 64 channel signal. 
88.2/96 kHz 
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. 
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 
sample rate, the output word clock is 48 kHz. 
MADI Input Status 
Displays the state of the current input signal: 
•  Channel format (64 or 56 channels) 
•  Frame format (48K or 96K) 
•  Sample rate (measured) 
•  Active input (optical or coaxial) 
Sync Check 
RME’s exclusive SyncCheck technology provides an easy to use check and display of the cur-
rent clock status. The SyncCheck field indicates whether no signal (No Lock), a valid signal 
(Lock) or a valid and synchronous signal (Sync) is present at each of the digital clock source 
inputs.
