Input Connections

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.

Loudspeaker Output Connections

MMA81502 (120V)

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;

8 Ohm, 25V, and 70V via Output Transformer

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.
