Buffer Size (Latency)
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).
USB Diagnosis indicates USB transmission errors. The display will be reset on any start of a
playback/record. More information can be found in chapter 38.3.
Options
DSP
– Record EQ
Switches EQ of all input channels into the recording path. In case Loopback has been activated
the EQ of the Output channel is within the recording path. See also chapter 26.6.
TMS activates the transmission of Channel Status data and Track Marker information on AES
and SPDIF inputs. In case these information are not required the feature should be turned off.
Sample Rate Conversion
The SRC can be connected to one of the digital inputs. Choices are AES, SPDIF (coaxial) and
SPDIF optical. The format ADAT optical is not routed through the SRC in any case. For more
details see chapter 21.5.
Optical Out
The optical TOSLINK output can operate as ADAT or SPDIF output. ADAT: includes channels
ADAT 1 to 8. SPDIF: includes channels SPDIF opt. L/R, in TotalMix ADAT 1/2. In SPDIF mode
Channel Status is fixed to Consumer.
WDM Devices
Reduce the number of WDM devices to the ones really needed to improve performance of the
operating system.
Clock Options
Sample Rate
Sets the currently used sample rate. Offers a central and comfortable way of configuring the sam-
ple 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
(AES, SPDIF, Optical = SPDIF optical or ADAT optical). If the selected source isn't available
(Input Status No Lock), the unit will change to the next available one (AutoSync). If none is avail-
able then the internal clock is used. The current clock source is displayed to the right.
Input Status
Indicates for inputs AES, SPDIF (coaxial) and Optical (ADAT optical or SPDIF optical) whether
there is a valid signal (Lock, No Lock), or if there is a valid
and synchronous signal (Sync). The
third column shows the sample frequency detected by the hardware (coarse recognition, 32 kHz,
44.1 kHz, 48 kHz etc.).
