14.Fuse

The fuse is located within the cap of the fuse holder. If the fuse fails, THE FUSE MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatedly blows fuse, it should be taken to a qualified service center for repair.

WARNING: The fuse should only be replaced when the power cord has been disconnected from its power source!

15.AC Outlet (Unswitched)

Provides AC power for auxiliary equipment with power consumption less than 300 Watts. This outlet is not controlled by the power switch (#13).

16.Outputs

A direct output and transformer isolated outputs are provided to allow proper interface between the amplifier and the loudspeaker system. The direct output allows connection to a 4 Ohm speaker system. To use this output, remove the jumper between the 4 Ohm terminal and the XFMR LINK terminal. Connect the loudspeaker system to the 4 Ohm and GND terminals.

For transformer isolated outputs, ensure the jumper is inserted between the XFMR LINK terminal and the 4 Ohm terminal, then connect load between the desired output and COM. The Low Cut switch (#19) should be ON. See LOUDSPEAKER OUTPUT CONNECTIONS below for details.

17.Module Input Ports 1–6

Accepts optional PLUG-IN MODULES. The modules should be selected by installation requirements. These ports accept and support PLUG-IN MODULES that do not require a +5V power supply. For 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.

NOTE: No more than two of the optional OPMOutput Power Modules may be used in each MMA mainframe.

18.Module Input Ports 7–8

Accepts optional PLUG-IN MODULES. The modules should be selected by installation requirements. These ports accept and support specific PLUG-IN MODULES that do require a +5V power supply, however any PLUG-IN MODULE may be utilized. For 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.

NOTE: No more than two of the optional OPMOutput Power Modules may be used in each MMA mainframe.

19.Low cut switch

Provides a 6 dB/octave low frequency roll-off at 60 Hz. To be used when the transformer isolated power outputs are connected to the loudspeaker system.

20.Preamplifier Out

Provides a line level output of Master Level mix output to drive external devices such as signal processors, hearing assistance systems, or recording equipment. The input impedance of the equipment should be greater than 600 Ohms.
