WDM Devices
Not before Vista the OS had been capable to handle more than 32 WDM stereo devices. There-
fore under W2k/XP it often makes sense to intentionally limit their number. Otherwise channels
or MIDI ports might vanish from the system.
Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and GSIF
data, as well as affecting system stability (see chapter 13/14). GSIF and WDM can be set from
32 to 512 samples. Above 512, only ASIO is affected.
AEB / TEB
ADAT In switches the input
ADAT from the optical connector
to the internal connector ADAT
In. Here an Expansion Board
(AEB4-I, AEB8-I, TEB) can be
connected.
Options
SyncAlign guarantees synchro-
nous channels when using WDM
multitrack software. This option
should only be switched off when
the software does not work cor-
rectly with SyncAlign activated.
With Interleaved activated, WDM
devices can be used as 8-
channel devices (see chapter
12.3).
TMS activates the transmission
of Channel Status data and
Track Marker information from
the SPDIF and AES input signals.
SPDIF Out
The SPDIF output signal is constantly available at the phono plug. After selecting 'Optical' it is
also routed to the optical TOSLINK output. For further details about the setting ‘Professional’
please refer to chapter 23.2.
SPDIF In
Defines the input for the SPDIF signal. 'Optical' relates to the optical TOSLINK input, 'Coaxial' to
the RCA socket, 'Internal' to the jumper SPDIF IN.
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
sample rate, the output word clock is 48 kHz.
Breakout Cable
Checking 'XLR' lowers the analog Line output level by 6 dB. Using the balanced XLR output
cable then results in correct reference levels.
Input Level
Choice of the reference level and with this of the sensitivity of the analog Line input.
Output Level
Choice of the reference level and with this of the level at the analog Line output.
