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. L iquid 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.
• Use only the included power cord for this unit. Using other types may be a fire and electrical shock hazard.
• The power to this device is not completely shut off even when the power switch is turned off. L ocate the device cl ose to the AC outlet so you can easily reach the power plug.
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
• XLR-type connectors are wired as f ollows: pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Replacing abrasive parts
• 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.
Influence on cell phone usage
• Using a cel l phone (mobile telephone) near this unit may induce noise. If noise occurs, use the telephone away from the unit.
Volume level setting
• 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.

EMX88S/EMX68S—Owner’s Manual

Introduction

Thank you for purchasing the Yamaha EMX88S/EMX68S Powered Mixer. The EMX88S/EMX68S has the following features. In order to take full advantage of the EMX 88S/EMX68S 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

5
• The EMX88S/EMX68S features eight input channels (EMX88S ), s ix input channels (EMX68 S) that support a wide range of audio sources, from microphones to line-level devices. The microphone input for each channel has +15 V phantom power for use with con­denser-type microphones.
• Two powerful main amps are built-in to deliver 400W + 400W (800W monaural when bridged). According to your needs, the output signal to the power amps can be either stereo [MAIN L-R], [MAIN (L+R)] + monitor [MAIN (L+R) - MON], or [MAIN (L+R)] (bridge connection).
Stereo The stereo-mixed main signal will be output from speaker output jacks A and B of the EMX88S/ EMX68S. Either one or two speakers can be con­nected to each set of speaker jacks.
[MAIN (L+R)] + monitor The monaural-mixed main signal will be output from speaker jacks A of the EMX88S/EMX68S , and the monitor signal will be output from speaker jacks B. Either one or two speakers can be con­nected to each set of speaker jacks.
[MAIN (L+R)] (bridge connection) The two power amps will be bridged, and the mon­aural-mixed main signal will be output from the BRIDGE jack. This allows high-volume output when using only one speaker.
• 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.
• The 16 built-in effe ct types are equivalent in quality to those of the acclaimed Yamaha SPX series of multi­eff e ct units, and allow a variety of effects to be applied to add reverb or ambience to vocals or instruments. The16 types include T AP DELAY, which lets you easily adjust the delay time.
• The EMX88S/EMX68S has implemented “EEEngine”, Yamaha’s epochal amp drive technology to create an unrivaled high-efficiency drive. The EEEngine’s energy-saver/low-heat-generation 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 les s-restrictive i nstallation requirements related to heat generation.

Connecting an electronic musical instrument
To the EMX88S/EMX68S’s LINE jacks, you can connect an electronic musical instrument such as a synthesizer, drum machine, signal processor connected to an electric guitar, etc. Refer to the diagram below to make a stereo connection from the output jacks (such as L/MONO and R) of an electronic musical instrument to the LINE jacks in stereo.
If you wish to connect multiple instruments, make a monaural connection as shown below.
EMX88S (EMX68S)
• You can also use the Hi-Z jacks and Super Hi-Z jacks to connect multiple instruments. You cannot use the Hi-Z jack and the Low-Z jack for the same channel at the same time. If a microphone has already been connected to the Low-Z jack of a chan­nel, you cannot connect an instrument to the Hi-Z jack of the channel.
