Word Clock - RME Audio DIGIFACE User Manual

Buffer Size
The setting 'Buffer Size' determines the latency between incoming and outgoing data, as well
as affecting system stability. We recommend selecting the highest value here (8192 samples) -
the system will still run comfortably.
Options
'Alt. ASIO Mode' activates a different ASIO callback method. This setting is performed in real-
time and under operation. Therefore it's very easy to check whether this setting results in any
performance advantages. This setting is recommended for Logic (emagic) and Spark (TC).
SPDIF In
Defines the input for the SPDIF
signal. 'Coaxial' relates to the
phono socket, 'ADAT1' to the
optical input ADAT1.
SPDIF Out
The SPDIF output signal is
constantly available at the phono
plug. After selecting 'ADAT1' it is
also routed to the optical output
ADAT1. For further details about
the settings 'Professional',
'Emphasis' and 'Non-Audio',
please refer to chapter 12.
Clock Mode
The card can be configured to
use its internal clock (Master), or
the clock source pre-defined via
Pref. Sync Ref (AutoSync).
Pref. Sync Ref
Used to pre-select the desired
clock source. If the selected
source isn't available the card will change to the next available one. The currently used clock
source and sample rate is displayed in the AutoSyncRef display.
The automatic clock selection checks and changes between the clock sources ADAT optical,
SPDIF, word clock and ADAT Sync. The latter is recommended especially for sample-accurate
transfers under ASIO 2.0.
System Clock
Shows the current clock state of the HDSP system. The system is either Master (using its own
clock) or Slave (AutoSync Ref).
Hardware State
This display shows the current state of the I/O-box:
I/O Box error: I/O-box not connected or missing power
I/O Box detected: The interface has found a I/O-box and tries to load the firmware
I/O Box locked: Communication between interface and I/O-box ok
