TC Electronic Studio Konnekt 48 - Manual (Page 17)

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.

Access the System Settings page by pressing the System Settings tab:
Buffer Size
1 System
Press to enter the page holding the system settings.
2 Buffer Size
The buffer size* can be set from 32 to 8192 samples.
The higher buffer setting, the longer latency through
Konnekt. The default buffer size is set to 256
samples. The driver latency is also indicated in ms
(milliseconds).
The displayed latency is the driver latency only! To
calculate the complete latency in your setup you
need to add the latency of converters, host (DAW),
plug-ins and e.g. DPC latency.
You should only increase the buffer size if you
experience problems such a clicks and pops in the
sound.*
* Relevant for PC version only. On Mac computers buffer size
is set in the audio application. For instance in Logic Pro go
to: Audio/Hardware drivers to set the buffer size.
Note - clicks and pops in the sound may also derive from
clock problems. These should be resolved first.

3 Clock Master
With the Clock Master parameter you select which of
the Konnekt units in your setup that will act as
System Clock Master.
