EMX860ST—Owner’s Manual
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.

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
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 per-
formance, 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 micro-
phone input for each channel has a +48 V phan-
tom powering for use with condenser-type
microphones.
• A built-in independent monitoring power ampli-
fier rated at 200 W, in addition to two powerful
main power amplifiers (200 W + 200 W — total
400 W monaural in bridge connection), is capa-
ble of driving stereo main speakers and monitor-
ing 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 vol-
ume level and frequency response of the main
speakers and monitor speakers.
• Two limiter circuits are built-in to prevent exces-
sive 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 instru-
mental sounds.
