Options 
AEB activates the internal connector as ADAT1 input instead of the optical TOSLINK. An ex-
pansion board (AEB4-I, AEB8-I, TEB) can be connected here. 
TMS activates the transmission of Channel Status data and Track Marker information for the 
SPDIF input. 
WDM Devices 
Not before Vista the OS had been 
capable to handle more than 32 
WDM stereo devices. Therefore 
under W2k/XP it often makes sense 
to intentionally limit their number. 
SPDIF In 
Defines the input for the SPDIF 
signal. 'Coaxial' relates to the RCA 
socket, 'Optical' to the optical 
TOSLINK input ADAT1, 'Internal' to 
the jumper 'AEB1 In/CD In'. 
SPDIF Out 
The SPDIF output signal is 
constantly available at the phono 
plug. After selecting 'ADAT1' it is 
also routed to the optical TOSLINK 
output ADAT1. For further details 
about the settings ‘Professional’, 
‘Emphasis’ and ‘Non-Audio’, please 
refer to chapter 22.2. 
SPDIF Freq. 
Displays the sample rate of the 
signal at the SPDIF input. 
Time Code 
Shows the time code from the input ADAT Sync. 
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. 
Clock Mode 
The unit can be configured to use its internal clock source (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 unit will 
change to the next available one. The current clock source and sample rate is displayed in the 
AutoSync Ref display. 
The automatic clock selection checks and changes between the clock sources Word Clock, 
ADAT, ADAT Sync and SPDIF. 
System Clock 
Shows the current clock state of the HDSP system. The system is either Master (using its own 
clock) or Slave (see AutoSync Ref).
