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 Figure 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
on. Cover unoccupied INPUT PORTS with provided blank panels and secure with screws.
The loudspeaker outputs of the mixer/amplifier are 4 Ohms, 8 Ohms, 25V and 70V. Connect the
loudspeaker system to any ONE of these outputs. Class 2 wiring may be used.
There are two types of output: 4 Ohm Direct Output;
The method of connection differs in each case. Refer to Figure 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.
