BUFFER SIZE
1 System
Click this field to enter the page holding the system
settings.
2 ASIO Buffer Size (relevant for PCs only)
The buffer size* can be set from 32 to 8192 samples.
The default buffer size is set to 512 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),
and
plug-ins.
You should only increase the buffer size if you experience
problems such as clicks and pops in the sound.*
* Relevant for PC version only. On Mac computers, the 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.
SYSTEM CLOCK
3 Clock Master
With the Clock Master parameter, you select which
Konnekt unit in your setup will act as the System
Clock Master.
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 if it has
one or more digital inputs.* See “Sync Source” below.
4 Sync Source
The Sync Source parameter determines to which
input the Clock Master should sync. The DICE II™
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™ chip.
* The Desktop Konnekt 6 has no digital inputs.
Example 1: Studio Konnekt 48 as Clock Master:
Setting Clock Master and Sync Source
• The setup consists of two Studio Konnekt 48 units
connected via FireWire, a computer and an ADAT
interface.
• We assigned the nicknames “SK48 No1” and SK48
No2” to the two Studio Konnekt 48 units (Nicknames
are set on the Setup page).
The intention is to sync the entire setup to the ADAT
interface.
SYSTEM SETTINGS – SYSTEM PAGE
• Set Clock Master on the System Settings page to
“SK48 No1” as this 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” is selected as clock source.
Example 2: Studio Konnekt 48 – Jitter Elimination
(This example is not relevant for the Desktop Konnekt 6.)
In this setup, we have a CD player in the system.
In terms of digital clocking, a CD player cannot be
controlled externally and can thus only act as master.
Again we have to stress that not only does Studio
Konnekt 48 provide a high quality clock, but it also
facilitates excellent jitter-elimination that will clean up a
less-than-perfect digital signal from an external source
such as a CD player.
• The CD player is connected to “SK48 No1” via Tos-link
(optical SPDIF).
• “SK48 No1” is selected as Clock Master on the
System Settings page, and the Sync Source
parameter is set to “Optical SPDIF”.
• The R4000 is connected to the other Konnekt in the
setup (SK48 No2) and it is set to slave to “SPDIF
1/2”.
5 Sample Rate
44.1 kHz
48 kHz
88.2 kHz
96 kHz
176.4 kHz
192 kHz
Typically, the sample rate is set within your host
application. If, for example, you play a 44.1 kHz project,
the sample rate automatically shifts to 44.1 kHz. If you
later load and play a 48 kHz song, the sample rate shifts
to 48 kHz.
Please note that even though your Konnekt receives
information about the sample rate, it still provides the
actual digital clock.
6 Clock Recovery and Lock Status
(This section is relevant for the Studio Konnekt 48 only.)
If the Clock Recovery function is disabled, the following
status indications can be given:
INTERNAL LOCK
Indicates that the system is locked to the master
Studio Konnekt 48 unit.
EXTERNAL LOCK
Indicates that the system is locked to an external
digital device connected to the master Studio Konnekt
48’s digital inputs.
