This receptacle is for the IEC line cord (included) that provides AC power to the unit.

Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire should be grounded properly. To prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are properly grounded.

13. Power Switch

This rocker switch applies mains power to the unit.

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

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 OPM™ Output Power Modules may be used in each MMA mainframe.

19. Low cut switch

Provides a 6 dB/octave low frequency roll-off at 60Hz . 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.

21. Power Amplifier Input

Provides a direct input to the power amplifier with an input sensitivity of 1 Volt. When an RCA phono plug is inserted into this input, the connection between the preamp output and the power amp input is internally disconnected allowing direct access to the power amplifier. Using this input along with the preamplifier output (#9), a signal processor can be inserted between the mixer and the power amplifier.

22. Bridge In/Out

Provides an output signal that is independent of the Master level, Low EQ, and High EQ controls. It also may be used as a mixing output point when the similar terminal of another mixer/amplifier is connected to this terminal. A separate tape recorder output may be taken from this point without interaction of EQ and Master level control. The input impedance of the equipment connected to this terminal should be greater than 10k Ohms.

23. Program Input

Provides an auxiliary input that accepts signals from other sources such as another mixer or mixer/amplifier. The signal level at this input is controlled by the PROGRAM level control on the front panel and is fed to the mix bus. The Program input may be regarded as "Channel 9" without PLUG-IN MODULE capability.

NOTE: This input is muted whenever the Mute 1 bus is activated (#24).

24. Ext Mute 1/2

When either of these terminals is connected to the Shield terminal (SHD), the respective mute bus is activated and fed to any PLUG-IN MODULES utilizing its mating function. For details about the module's mating function, refer to the individual PLUG-IN MODULE Instruction Guide.

25. External Volume Control

These connections allow the use of an external (remote) master volume control. For complete command of the volume from the remote control, the front panel Master Level control (#1) must be set at its maximum (10) position. The remote volume control should be connected as shown in Figure 1, with the clockwise terminal connected to the Shield (SHD); the wiper connected to the Control (C); and the counterclockwise terminal connected to the Voltage (V). Using a 1ok Ohm linear taper potentiometer will provide approximately 30 dB attenuation, while using a 1ook Ohm linear taper potentiometer will provide approximately 60 dB attenuation. See Figure 1.
