Klark Teknik DN9650 - AES50-to-CM1 converter, fixed 1:1 routing (3×24ch). Supports 96/48kHz; full 48ch requires using two AES50 ports.
Overview of the DN9650 design
The DN9650 was originally designed for operation at 96 kHz only, as this was the standard clock speed for all Midas consoles. The 48 kHz clocking option was added later through a software update.
Fixed routing structure
The internal routing design of the DN9650 follows a fixed 1:1 structure between AES50 and the CM1 card. This configuration cannot be changed:
- AES50 Port 1: channels 1-24 bidirectionally
- AES50 Port 2: channels 25-48 bidirectionally
- AES50 Port 3: channels 49-72 bidirectionally
Operation at 48 khz
As a result, even though AES50 can technically carry 48 channels per port at 48 kHz, the DN9650 does not support this. To achieve 48 channels of audio, two AES50 ports must be used - Port 1 for channels 1-24 and Port 2 for channels 25-48. On an M32 console, this configuration requires both AES50 ports, leaving only the local I/O available for inputs and outputs.
