6.4Installation

The audio expander is suitable for either table-top or 19-inch rack installation. Four feet (for table-top use) and two brackets (for rack installation) are supplied.

Note

The center bracket positions can be used to secure the unit on a table or shelf. They can also be used to install the unit vertically to a wall.

The common (C) pin of the control output should always be connected. Whether the other pin that is connected is the normally closed (NC) or normally open (NO) depends on which action that take place when the control output is active (see table 6.4).
