There are eight INPUT PORTS for PLUG-IN MODULES. Select the appropriate modules for each
application. Plug the modules into the INPUT PORTS. Slide them between the card-edge guide
rails and secure them with the provided screws as shown in

. Ensure screws are
sufficiently tightened for proper grounding. For connection details, refer to the individual PLUG-
IN MODULE Instruction Guide.
CAUTION: Plug-in Modules should not be inserted or removed while the mixer/amplifier is turned
on. Cover unoccupied INPUT PORTS with provided blank panels and secure with screws.
