EMX66M—Owner’s Manual
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 perfor-
mance, please read this owner’s manual carefully, and keep it in a safe place for future
reference.
Features
• The EMX66M provides six input channels com-
patible with mic/line signals, including high-
impedance 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 sec-
tion. 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 speak-
ers.
• 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 instru-
mental 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 genera-
tion.
