XLR connector panels
XLR connectors are used for output of the balanced signal channels of the changeover. These channels are only
available when the MCO-OPT-8618 option has been installed.
Each channel has two connectors:
• IN 1/2 9-pin D-sub carrying the inputs from the two MSG-5300 Master Sync Generators
Note: the MSG outputs are on XLR connectors. A special “Y” cable is provided to connect those
outputs to this connector.
• OUT XLR balanced output.
