System Connections

Power

Make sure the power switch is off before connecting the external power supply.

Power should be turned off of every MCS-3000X Expander.

There is a strain relief clip on the back of the unit, to prevent accidental unplugging.

Pass the small plug end of the power supply through this clip. Loop it around and pass it through again..

Then plug it in.

Time Code

The MCS-3400 and MCS-3800 have a built in time code reader and display.

If you wish to display time code, connect a source of SMPTE ("LTC") to the Sync In jack.

The input jack is 1/4”, unbalanced, that is, tip and sleeve.

While the time code reader responds to a fairly wide range of input levels, -10 dBm is the recommended nominal level.
