TC electronic SDN BHD 48 - Manual (Page 33)

In a digital setup, it is important that all connected
devices run at the same sample rate. The Clock
Master device defines this sample rate, and
distributes a digital clock based on this sample rate to
all devices in the setup. There can be one, and only
one clock master in a digital setup, and you cannot
select your computer here; the clock master device is
always your audio interface. However, the Clock
Master device may sync to an external device. See
“Sync Source” below.
4 Sync Source
The Sync Source parameter determines to which
device the Clock Master should sync. The DICE II
TM
FireWire chip provides excellent clock and in many
setups the “internal” option is the best choice.
However, you may sync to any digital device attached
to the digital inputs of a Konnekt in your system and
benefit from the outstanding JetPLL jitter elimination
technology also provided by the DICE II
TM chip.
Example 1: Studio Konnekt 48 as Clock Master:
Setting Clock Master and Sync Source.
•
The setup consists of 2 Studio Konnekt 48 units
connected via FireWire, a computer and an ADAT
interface.
• We assigned the nick-names “SK48 No1” and SK48
No2” to the two Studio Konnekt 48 units. (nick-
names are set on the Setup page).
The intention is to sync the entire setup to the ADAT
interface.
• Set Clock Master on the System Settings page to
“SK48 No1” as this is is the physical Konnekt unit
that will determine the clock master.
• Set Sync Source to ADAT as this is the connection on
the Clock Master unit that you would like to sync to.
That is basically it. The Sample Rate should only be set if
Internal Clock source is selected.
Example 2: Studio Konnekt 48 - Jitter Elimination
In this setup we have a CD player in the system. In terms
of digital clocking a CD player is uncontrollable and can
thus only act as master.
