Switching Multi-Channel Components

Many components in both home and car audio have more than one set of inputs and/or outputs. When a

multi-channel component position is selected at the MVP Control Panel, a Switching System must have the

potential to switch any of that component’s inputs or outputs simultaneously. Some Matrix System

Switching Modules (the 1310/12 and the 1320/22) have two sets of relays which can handle the inputs

and/or outputs of such components.
