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, TCO, Sync In). 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 and
192 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.
