Important
Read the Following Before operating the EMX860ST
Warnings
•Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock may result.
•Connect this unit’s power cord only to an AC outlet of the type stated in this Owner's Manual or as marked on the unit. Failure to do so is a fire and electrical shock hazard.
•Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a fire and electrical shock hazard.
•Do not place heavy objects, including this unit, on top of the power cord. A damaged power cord is a fire and electrical shock hazard. In particular, be careful not to place heavy objects on a power cord covered by a carpet.
•If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit, turn it off immediately. Remove the power cord from the AC outlet. Consult your dealer for repair. Using the unit in this condition is a fire and electrical shock hazard.
•Should this unit be dropped or the cabinet be damaged, turn the power switch off, remove the power plug from the AC outlet, and contact your dealer. If you continue using the unit without heeding this instruction, fire or electrical shock may result.
•If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a replacement. Using the unit with a damaged power cord is a fire and electrical shock hazard.
•Do not remove the unit's cover. You could receive an electrical shock. If you think internal inspection, maintenance, or repair is necessary, contact your dealer.
•Do not modify the unit. Doing so is a fire and electrical shock hazard.
Cautions
•Allow enough free space around the unit for normal ventilation. This should be: 20 cm at the sides, 40 cm behind, and 40 cm above.
These distances should also be adopted when rack-mounting the unit. For normal ventilation during use, remove the rear of the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up inside and may cause a fire.
•This unit has ventilation holes at the front, rear and sides to prevent the internal temperature rising too high. Do not block them. Blocked ventilation holes are a fire hazard.
•Clean the contacts of the phone plug before connecting it to the SPEAKERS jack of this unit. Dirty contacts may generate heat.
•Use only speaker cables when connecting speakers to amplifier outputs. Using other types of cables is a fire hazard.
•Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A damaged power cord is a potential fire and electrical shock hazard.
•Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.

4 Important
Operating Notes
•The digital circuits of this unit may induce a slight noise into nearby radios and TVs. If noise occurs, relocate the affected equipment.
•Using a mobile telephone near this unit may induce noise. If noise occurs, use the telephone away from the unit.
•XLR-type connectors are wired as follows:
pin 1: ground, pin 2: hot (+), and pin 3: cold (–).
•Do not set all equalizer controls and faders to maximum. Doing so may cause oscillation depending on the condition of the connected unit and speakers, and may damage the speakers.
•The performance of components with moving contacts, such switches, rotary controls, faders, and connectors, deteriorates over time. The rate of deterioration depends on the operating environment and is unavoidable. Consult your dealer about replacing defective components.
EMX860ST—Owner’s Manual
Introduction 5
Introduction
Thank you for purchasing the Yamaha EMX860ST Powered Mixer. The EMX860ST has the following features.
In order to take full advantage of the EMX860ST and enjoy long and trouble-free performance, please read this owner’s manual carefully, and keep it in a safe place for future reference.
Features
•The EMX860ST features eight input channels that support a wide range of audio sources, from microphones to line-level devices. The microphone input for each channel has a +48 V phantom powering for use with condenser-type microphones.
•A built-in independent monitoring power amplifier rated at 200 W, in addition to two powerful main power amplifiers (200 W + 200 W — total 400 W monaural in bridge connection), is capable of driving stereo main speakers and monitoring speakers on stage simultaneously in a sophisticated PA system environment.
•Individual seven-band graphic equalizers are provided to the main and the monitor sections. In this way, you can individually adjust the volume level and frequency response of the main speakers and monitor speakers.
•Two limiter circuits are built-in to prevent excessive input levels to the amp.
•A digital effect with three selectable effect types is built-in. A variety of effects can be applied to add reverberation or ambiance to vocals or instrumental sounds.

1Equalizer 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 |

MID: |
2.5 kHz |

LOW: |
100 Hz |

2Monitor controls (MONI)
For each channel, this controls the amount of signal that is sent to the MONI bus.
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.
3Effect 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.
4PAN 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).
5Level control (LEVEL)
This adjusts the output level for each channel.
6Pad 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).

0Graphic equalizer
The EMX860ST has a 7-band graphic equalizer for adjusting the frequency response of the
MONI bus signal. This allows you to cut or boost each frequency band by a maximum of ± 12dB. You can use these sliders to reduce the level of frequency bands at which feedback easily occurs. Frequency response is flat when a slider is in the center position. Moving a slider in the positive direction will boost, and in the negative direction will cut.
These graphic equalizer settings affect both the MONI bus signal output to the speakers and the line level signal sent from MONITOR jack signal (input/output panel 6).

This control adjusts the effect signal level sent to the MONI bus from the built-in digital effect.
BMASTER control
This control adjusts the MONI bus signal output level.
This setting is output to both the front and rear panel MONITOR jacks and appears in the MONI bus signal.

DGraphic equalizer
The EMX860ST has a 7-band graphic equalizer for adjusting the frequency response of the ST
bus signal. This allows you to cut or boost each frequency band by a maximum of ± 12dB.
These graphic equalizer settings affect both the ST bus signal output to the speakers and the line level signal output from the MAIN (STEREO) jack (input/output panel 6).
EEFFECT RTN control
Use this control to adjust the effect signal sent to the ST bus from the built-in digital effect.
FAUX IN control
This adjusts the amount of signal that is sent from the AUX IN jack to the ST bus.
GTAPE IN
This adjusts the amount of signal that is sent from the TAPE IN jacks to the ST bus.
HMASTER control
This control adjusts the ST bus signal output level. This setting is output to the SPEAKERS L/ R/L+R, BRIDGE jacks and the MAIN (STEREO) jack on the rear panel and appears in the ST bus signal.
IPeak level indicator
This indicator allows you to monitor the level of the signal which is output from the MAIN (STEREO) jack (input/output panel 6).
Note: To avoid distortion, adjust the MASTER control (H) so that the 0 indicator lights occasionally.
