Volume Control, providing volume control in
local-zone systems (see above).
4-Pin Screw Connector: Connects to the
Aux Power

in installations where the Wallplate is locat-
ed more than 250 feet from the iPort.
Note: The 4-Pin connector has two parallel
sets of Supplemental Power connections.
You can use either set.
In addition to the above connections, the
rear panel also has two RotoLock
