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
Accepts optional
CAUTION:
NOTE: No more than two of the optional OPM™ Output Power Modules may be used in each MMA mainframe.
18.Module Input Ports
Accepts optional
CAUTION:
NOTE: No more than two of the optional OPM™ Output Power Modules may be used in each MMA mainframe.
19.Low cut switch
Provides a 6 dB/octave low frequency
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.
