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 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 con-
nected 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 con-
nected 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 multi-
effect 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.
