These plots show the nominal output and maximum output levels of signals received at the SPEAKERS jacks. If the output level is +4dB (Level Meter “0”), the internal power amplifier will deliver 60W into a 4Ω load. If the output level is +11dB (LIMITER indicator lights), the internal amplifier will deliver a maximum of 300W into a 4Ω load. If you are using the BRIDGE jack, the internal power amplifier will deliver 120W into an 8Ω load with a +4dB signal, and a maximum of 600W into an 8Ω load with a +11dB signal.

Precautions

WARNING

Installation

•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 allow water to enter this unit or allow the unit to become wet. Fire or electrical shock may result.

•Do not place a container with liquid or small metal objects on top of this unit. Liquid or metal objects inside this unit are 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.

•The power to this device is not completely shut off even when the power switch is turned off. Locate the device close to the AC outlet so you can easily reach the power plug.

•Use only the included power cord for this unit. Using other types may be a fire and electrical shock hazard.

Operation

•Do not scratch, bend, twist, pull, or heat the power cord. 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.

•If lightning begins to occur, turn off the power switch of the unit as soon as possible, and unplug the power cable plug from the electrical outlet.

•If there is a possibility of lightning, do not touch the power cable plug if it is still connected. Doing so may be an electrical shock hazard.

In case an abnormality occurs during operation

•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.

•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 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.

CAUTION

Installation

•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.

•This unit has ventilation holes at the rear to prevent the internal temperature rising too high. Do not block them. Blocked ventilation holes are a fire hazard.

•When rack-mounting the unit, allow enough free space around the unit for normal ventilation. This should be10 cm at the sides, 15 cm behind, and 25 cm above.

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.

Operation

•Use only speaker cables when connecting speakers to amplifier outputs. Using other types of cables is a fire hazard.

Maintenance

•Clean the contacts of the phone plug before connecting it to the SPEAKERS jack of this unit. Dirty contacts may generate heat.

PRECAUTIONS FOR OPERATION	– FOR CORRECT OPERATION –
Connector pin assignments		Influence on cell phone usage

•XLR-type connectors are wired as follows: pin 1: ground, pin 2: hot (+), and pin 3: cold (-).

Replacing abrasive parts

•Using a cell phone (mobile telephone) near this unit may induce noise. If noise occurs, use the telephone away from the unit.

Volume level setting

•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.

•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.

Introduction

Thank you for purchasing the Yamaha EMX66M Powered Mixer.

In order to take full advantage of the EMX66M 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 EMX66M provides six input channels compatible with mic/line signals, including highimpedance input suitable for an electric-acoustic guitar. The EMX66M has ample power, with a maximum output of 300 W+300 W (600 W with bridge connection), and is suitable for a wide range of applications from installed systems to small-scale PA systems.

•A two-channel power amp is built-in. The input signals for the two channels can be selected as MAIN+MAIN, MAIN+MONITOR, or MAIN (bridge connection).

•Independent 7-band graphic EQ is provided for both the MONITOR section and the MAIN section. This allows the volume and frequency response to be adjusted separately for the main speakers and monitor speakers.

•The power amp section has a limiter circuit to prevent sound distortion and protect the speakers.

•A digital effect with eight selectable effect types is built-in. A variety of effects can be applied to add reverberation or ambiance to vocals or instrumental sounds.

•The EMX66M has implemented “EEEngine”, Yamaha’s epochal amp drive technology to create an unrivaled high-efficiency drive.

The EEEngine’s energy-saver/low-heat-genera- tion design has reduced power consumption to 50% or less, and reduced heat generation to 35% or less (in field applications, compared to Yamaha’s previous models), and has lead to a reduction in energy cost and to less-restrictive installation requirements related to heat generation.
