Removing and Installing the I/O Card and Setting the Audio Gain

NThe I/O cards are hot-swappable. You do not need to power down the switcher to remove an I/O card.

Input and output circuit cards (figure 6-13 through figure 6-15) can be replaced for fault correction. Audio output cards must be removed if you want to change the output audio gain. Beyond those actions, you can increase or decrease the I/O configuration (size) of the Matrix 12800 by adding or removing I/O cards and then rerunning the Virtualization/Control Program (see chapter 3, “Virtualization/ Control software”).

The following table identifies the number of inputs that each input card supports and the number of outputs that each output card supports. Use this table to determine how the size of the matrix changes with the removal or installation of a single card.

BME	Number of inputs	Number of outputs
	per input card	per output card
Sync	32	64
Wideband/video	32	16
Audio	16	16
