[. . . ] C) The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. Unplug this apparatus during lightning storms or when unused for long periods of time. [. . . ] AC Outlet (Unswitched) Provides AC power for auxiliary equipment with power consumption less than 300 Watts. Outputs A direct output and transformer isolated outputs are provided to allow proper interface between the amplifier and the loudspeaker system. To use this output, remove the jumper between the 4 Ohm terminal and the XFMR LINK terminal. 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. 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 OPMTM Output Power Modules may be used in each MMA mainframe. 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 OPMTM Output Power Modules may be used in each MMA mainframe. 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. 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. 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. 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. [. . . ] If using the transformer isolated outputs be sure that the Low Cut switch is ON. There are two types of output: 4 Ohm Direct Output; 8 Ohm/25V, 70V, and 100V via Output Transformer The method of connection differs in each case.
