Level
Line In
Defines the reference level of the rear analog inputs 5-8. The available settings are -10 dBV, +4
dBu and LoGain.
Line Out
Defines the reference level of the rear analog outputs 1-6. The available settings are -10 dBV,
+4 dBu and HiGain.
Phones
Defines the reference level of the analog outputs 7/8. The available settings are -10 dBV, +4
dBu and HiGain.
Clock Mode
Sample Rate
Used to set the current sample rate. This is the same setting as in the Audio MIDI Setup, just
added here for your convenience.
At ongoing 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, Optical, SPDIF coax., = Slave). If the selected source isn't available, the unit will change
to the next available one (AutoSync). If none is available then the internal clock is used. The
current clock source is displayed to the right.
Input Status
Indicates for each input (Word, optical, SPDIF coax.) whether there is a valid signal (Lock, No
Lock), or if there is a valid and synchronous signal (Sync). The second row shows the sample
frequency measured by the hardware. In Clock Mode the clock reference is shown (Current...).
See also chapter 31.1.
Output Format
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.
Optical
The optical TOSLINK output can operate as ADAT or SPDIF output. The Channel Status is
fixed to Consumer state.
Note: The optical input detects the incoming format automatically.
SPDIF coax.
The coaxial SPDIF output can have the Channel Status Consumer or Professional. For further
details please refer to chapter 24.2.
