Hammerfall® DSP System Multiface

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 board itself will still run comfortably.
Options
'Alt. ASIO Mode' activates a different ASIO callback method. This setting is performed in realtime
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, 'ADAT' to the
optical TOSLINK input.
SPDIF Out
The SPDIF output signal is
constantly available at the phono
plug. After selecting 'ADAT' it is
also routed to the optical output
ADAT. 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
