Euphonix CO-600 Change-Over System For New Core DF66 Redundancy

The CO-600 has two primary functions: 1) a MADI splitter that provides 2 MADI

outputs for each MADI input and 2) a MADI switchover that switches each MADI

output between Primary and Backup MADI sources. Figure 1 provides a conceptual

block diagram of signal ow and behavior. External MADI inputs are distributed to both

the Primary Core and the Secondary Core so that the sources are always available to both

cores. The MADI outputs from each core are connected to the CO-600 and available for

switchover during a technical fault. The unpowered state of the system is connectivity

to the Primary Core.

A conceptual block diagram of a single CO-600 is provided in Figure 2. Features

available include redundant PSU’s with dual IEC AC inlets, GPIO, Fan Tray, CMM,

Chassis Control module, Chassis control linking, environmental sensors, Ethernet, and

up to four Change-over cards.
