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. Details about ‘Professional’ see chapter 23.3.
Phones
Choice of the reference level and with this of the level at the analog phones output. Lo-Power
offers reduced background noise which is useful with highly sensitive headphones.
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 sam-
ple 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).
Input Status / Pref. Sync Ref
SyncCheck indicates whether
there is a valid signal (Lock, No
Lock) for each input (ADAT,
SPDIF, AES, Word/TCO and
Sync Internal), or if there is a
valid and synchronous signal
(Sync).
In the third row the sample rate
measured by the hardware is
shown.
The first row is used to pre-
select the desired clock source.
If the selected source isn't
available, the unit will change
to the next available one auto-
matically. The current clock
source and sample rate is dis-
played in the System Clock
field.
The automatic clock selection checks and changes between the clock sources ADAT, AES,
SPDIF, Word/TCO and Sync Internal.
System Clock
Shows the current clock state of the HDSPe system. The system is either Master (using its own
clock) or Slave (see AutoSync Ref).
