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 EMX88S/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

•The EMX88S/EMX68S features eight input channels (EMX88S), six input channels (EMX68S) 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 con- denser-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 mon- aural-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 effect types are equivalent in quality to those of the acclaimed Yamaha SPX series of multieffect units, and allow a variety of effects to be applied to add reverb or ambience to vocals or instruments. The16 types include TAP 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 less-restrictive installation requirements related to heat generation.
