TC electronic SDN BHD 48 5Sample Rate, Prevent from changing sample rate, System Settings

SYSTEM SETTINGS

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 S/PDIF).

•“SK48 No1” is selected as Clock Master on the System Settings page and Sync Source is set to Optical S/PDIF.

•The R4000 is connected to the other Konnekt in the setup (SK48 No2) and it is set to slave to “S/PDIF 1/2”.

5Sample Rate

If Sync Source is set to “Internal”, the sample rate must be set. The options are:

44.1 kHz
48 kHz
88.2 kHz
96 kHz
176.4 kHz	(mixer not available)
192 kHz	(mixer not available)

Typically the sample rate is set by your host application. If you e.g. 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 Studio Konnekt 48

receives information about the sample rate it still provides the actual digital clock.

Prevent from changing sample rate

When any application in your system, operating systems alert sounds, Itunes etc. play a sound it will in most cases try to set the sample rate of your sound card/Konnekt. If you are trying to make music, this is not what you want. To prevent these interruptions we have therefore made the following options available.

WDM:

With this option selected, your DAW project (e.g. Cubase LE4) sets the current sample rate and no Windows alert sounds or media-players will accidentally change the sample rate.

WDM+ASIO:

With this option selected, the sample rate is set solely in the TC Near Control Panel (see previous page).

NONE:

With this option selected, any application, Windows sound, DAW project etc. is allowed to change the current sample rate.

DPC Safety Buffers (PC only)

Numerous things in a computer system may cause DPC spikes. Spikes, that momentarily may cause your application (Itunes, Cubase etc.) to stop playing. Therefore it is possible to set a safety buffer level preventing these spikes.

Select between:

Normal

Level 1

Level 2

Level 3

Use only as high a buffer level as necessary as the system latency increases with the buffer level.
