Klark Teknik U.S.A. Network Hardware DN9652 User Manual

9

• Supports up to 64 bi-directional channels of 24-bit, 96kHz audio per network or 

AES50 port (DN9650 only) with 1:1 channel mapping.

• Supports operation at 48kHz and 96kHz sampling frequencies.  Bi-directional ASRC 

on every channel with bypass facility to isolate network domains.

• High channel count asynchronous sample rate conversion (ASRC).

• Platform-independent web browser configuration interface software hosted on 

integrated Linux web server.

• Ethernet port for remote computer connection (unit configuration and software 

updating).

• Ultra-high stability reference - grade 1 part per million (1 ppm) temperature-

controlled clock oscillator.

• User-selectable stop output clock facility if input clock fails to function, to propagate 

network failure across ASRC for automatic or manual redundancy switchover.

• Flexible third party interface clock synchronisation options:

• Network module incoming and outgoing clocks.

• Word clock input.

• Word clock output.

• Video black burst in (PAL/SECAM/NTSC formats in standard definition (SD) and 

high definition (HD) resolutions).

• Clock Synchronisation:

• Clock synchronisation scheme divided into two network domains, separated by 

the ASRC, and either domain can be selected as clock master;

• AES50 clock source (DN9650 only) may be internal or external (incoming AES50 

clock, word clock and video black burst);

• Network clock source may be incoming network module clock, word clock in or 

video black burst in.

• 100V-240V universal power supply, 50Hz to 60Hz.

• Upgradeability.

This manual is for DN9650 and DN9652 units running host software version 1.00 and 
later.

An Ethernet Control port is provided on the rear panel to facilitate software updates.

Both CM-1 and CM-2 network modules must only be changed by qualified service 
personnel.  Contact Midas Klark Teknik Limited for details.
