Sharing a Power Supply with an Extron Controller
The MLA VC10 Plus can share a power supply with any Extron MLC or IP Link control
processor.
NOTES: • Power cables must be at least 18 AWG.
• If the cable has a drain wire, it should be grounded at both ends. To avoid
introducing noise and static into audio channels, the chassis of the control
processor (if used), the power supply, the MLA VC10 Plus, and the amplifier
or mixer should all share a common ground.
• The 12 VDC power supply that ships with the MediaLink or IP Link control
processor can provide power for both the MLA VC10 Plus and the Extron
control processor. It is not included with the MLA VC10 Plus.
To connect the MLA VC10 Plus to the power supply and an Extron control processor
follow these instructions and see figure 7, below.
ATTENTION: Read the attention notice on page 11 for important information
about power supplies.
Check the polarity of the wires from the power supply and connect them to the captive
screw power input on the MLA VC10 Plus rear panel. Connect the same captive screw
sockets to the power input on the MLC or IP Link control processor.
NOTE: See the notes on page 11 for important information about wiring captive
screw connectors.
