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 F F i i g g u u r r e e 3 3 . 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

There are two types of output: 4 Ohm Direct Output;
8 Ohm, 25V, and 70V via Output Transformer
The method of connection differs in each case. Refer to F F i i g g u u r r e e 4 4 . If using the transformer
isolated outputs be sure that the Low Cut switch is ON.
Note: Impedance values shown in Figure 4 indicate total loudspeaker system (load) impedance.
