The signal of the MONI bus is sent to the speakers connected to the MONITOR A/B jacks and to the MONITOR jacks (input/output panel 6). Note: The signal is sent to the MONITOR bus from a location before the level control (5) of each channel. This means that it will not be affected by the setting of the LEVEL control. 1 –15 +15 LOW –15 +15 MONI 2 0 10 EFFECT 3 0 10 PAN 4 L R LEVEL 5 0 10 PAD 6 1 1 Equalizer controls (HIGH, MID, LOW) This is a 3-band equalizer that adjusts the high frequency range, mid frequency range, and low frequency range of each channel. Response is flat when the knobs are in the ▼ position. Rotating it toward the right will boost the corresponding frequency band, and rotating it toward the left will cut it. The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows. HIGH: 10 kHz ±15 dB shelving type MID: 2.5 kHz ±15 dB peaking type LOW: 100 Hz ±15 dB shelving type EMX860ST—Owner’s Manual 3 Effect control (EFFECT) For each channel, this controls the amount of signal that is sent to the EFFECT bus. The signal of the EFFECT bus passes through the EFFECT section and the built-in digital effect, and is sent to the external effect device connected to the EFFECT OUT jacks (input/output panel 3). Note: The signal is sent to the EFFECT bus from a location after the level control (5) of each channel. This means that the amount of signal that is sent to the EFFECT bus will be affected not only by the setting of the effect control, but also by the setting of the level control. 4 PAN control (BAL/PAN control for CH7/8) This knob adjusts the stereo image (L/R) for each channel. Adjust for equal volume on left and right with a sound source input to the CH7 and 8 LINE connectors (L/R). 5 Level control (LEVEL) This adjusts the output level for each channel. 6 Pad switch (PAD) (1–6 only) This switch attenuates the input signal by 30 dB. When connecting a line level device to channels 1–6, or if the mic input is distorted, turn this switch on (the pressed-in position).  Control panel ■ DIGITAL EFFECT section This section allows you to turn the built-in digital effect on/off and to select the effect type. ■ EFFECT section This section allows you to adjust the level of the signal sent from the EFFECT bus to an external effect device. 9 VOCAL L HALL 7 7 0 10 EFFECT OUT EFFECT S HALL ON 8 DIGITAL EFFECT 7 Effect select switch 9 EFFECT OUT control This adjusts the effect send level for an external effect device connected to the EFFECT OUT jack (input/output panel 3).

By using the PAD switches (control panel 6) you can connect any of the jacks to a wide range of sources from mics to line level devices (synthesizers or rhythm boxes etc.). The Lo-Z jacks can provide +48 V phantom power, allowing you to use condenser microphones. Both Hi-Z and Lo-Z are balanced, and are compatible with microphones of output impedance 50–600Ω or line level devices of 600Ω. The nominal input level is from –40 dB to –10 dB for the Hi-Z jacks, and from –50 dB to –20 dB for the Lo-Z jacks. Pin connections for the Hi-Z and Lo-Z jacks are as follows. Lo-Z jacks (XLR type) Hi-Z jacks (TRS phone jacks) Pin 1: ground Sleeve: ground Pin 2: hot (+) Tip: hot (+) Pin 3: cold (–) Ring: cold (–) S + - GND R T GND - + Note: It is not possible to simultaneously use both the Hi-Z and Lo-Z inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source. Phantom power is switched on/off in simultaneously for channels 1–8. For this reason, devices which do not require phantom power must be connected to the Hi-Z or LINE jacks if the PHANTOM +48 V switch (control panel M) is on. EMX860ST—Owner’s Manual 34 5 OUTPUT 6 2 Channel input jacks (MIC/LINE) 7–8 These are the input jacks for channels 7–8. Connect microphones to the MIC jacks. Connect line-level devices, such as synthesizers to LINE L (MONO)/R jacks if the devices are stereo sound sources. Use the LINE L (MONO) jack if the devices are monaural sound sources. The MIC jacks are balanced, and are compatible with microphones of output impedance 50– 600Ω. The LINE jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. Nominal input level is –50 dB for the MIC jacks and –20 dB for the LINE jacks. Note: The MIC and LINE inputs for channel 7 can be used simultaneously but their levels cannot be adjusted separately (Same for channel 8.) 3 Effect output jack (EFFECT OUT) The input of an external effect such as a delay or echo can be connected to this jack. The signal adjusted by the EFFECT control of each channel will be sent to the EFFECT bus, its level adjusted by the EFFECT OUT control, and output from this jack. The nominal output level and impedance are +4 dB/10 kΩ. 4 Foot switch jack (FOOT SW) You can connect a Yamaha FC5 foot switch (sold separately) to this jack and use it to turn the built-in digital effect on and off. The Digital Effect ON switch on the front panel must always be set to ON in order to use the foot switch.  Input/output panel 11 5 AUX IN/TAPE IN jacks These are input jacks that allow the signal from an external device to be added to the MAIN output. • AUX IN jacks: Connect these jacks to the output jacks of an external effects processor.

EMX860ST—Owner’s Manual Synthesizer Note: Set the power amp select switch of the POWER AMP section to the “MAIN MONITOR” position. If you are using an external effect, we recommend that you turn down the EFFECT RTN controls of the MAIN and MONITOR sections. If the external effect has a stereo output, it is possible to connect its output jacks to the LINE jacks of channels 5–6. However in this case, be sure that the EFFECT controls are turned all the way down for the channels into which the effect sound is being input. If the EFFECT controls are raised, feedback will occur, and your speakers may be damaged.  As a band PA 19 Using an external effect 1 Set the EFFECT section EFFECT OUT control to the √ position. 2 Raise the EFFECT controls for the channels to which you want the external effect to be applied. 3 Adjust the input level of the external effect so that the sound is not distorted at the input of the external effect. 4 Use the MAIN section AUX IN control to adjust the level of the sound processed by the effect.

If the device is not ventilated sufficiently, refer to the cautions given at the beginning of this manual and take appropriate measures to insure adequate ventilation. The load on the amplifier of this device was too great, and the protection circuit for the amplifier has operated. Possible reasons for the excessive load are an excessive level setting in the channel control section or main section, insufficient ventilation, or insufficient load impedance of the connected speakers. Please wait. When the device cools off, normal operation will resume automatically. However, please check the following three points to prevent the problem from recurring. If the level setting is excessive, lower it to the nominal level. You can refer to the peak level indicators of the main section when doing so. If the device is not ventilated sufficiently, refer to the cautions given at the beginning of this manual and take appropriate measures to insure adequate ventilation. If the load impedance (including a short) is too low, refer to the chapter on connections (page 13) and change the connections so that the impedance is correct. Connections between devices have come loose. Inspect the connections, and correct any faulty connections. Other The device may have malfunctioned. Please contact your dealer.
