Introduction
 
EMX3000—Owner’s Manual
 
remove the power plug from the AC outlet. Leaving it 
connected is a potential fire hazard.
• Do not touch the heatsink when this apparatus is in 
use. It can get very hot.

Operating Notes
 
• The digital circuits of this unit may induce a slight 
noise into nearby radios and TVs. If noise occurs, 
relocate the affected equipment.
• Using a mobile telephone near this unit may induce 
noise. If noise occurs, use the telephone away from 
the unit.
• XLR-type connectors are wired as follows: pin 1: 
ground, pin 2: hot (+), and pin 3: cold (–).
• Insert TRS phone jacks are wired as follows: sleeve: 
ground, tip: send, and ring: return.
• Do not set all equalizer controls and faders to maxi-
mum. Doing so may cause oscillation depending on 
the condition of the connected unit and speakers, and 
may damage the speakers.
• The performance of components with moving con-
tacts, such switches, rotary controls, faders, and con-
nectors, deteriorates over time. The rate of 
deterioration depends on the operating environment 
and is unavoidable. Consult your dealer about replac-
ing defective components.
 
Features
 
✦
 
The EMX3000 provides versatile inputs, such as two 
stereo input channels and two stereo sub inputs, as 
well as eight monaural input channels compatible 
with mic/line signals. The mixer also 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 signals out-
put to speakers can be selected as stereo (ST1 L-R), 
monitor+monaural (MONI 1- MONO), or monaural 
(bridge connection).
 
✧ 
 
Stereo
 
The main stereo mix signal is output from speaker 
output jacks L and R of the EMX3000. You can con-
nect one or two speakers to each speaker output jack.
 
✧ 
 
Monitor+monaural
 
The main monaural mix signal is output from speaker 
output jack R, and the monitor signal from speaker 
output jack L. You can connect one or two speakers to 
each speaker output jack.
 
✧ 
 
Monaural (bridge connection)
 
The two-channel power amp is bridge-connected, 
and the main monaural mix signal is output from 
BRIDGE jack. You can connect only one speaker for a 
much louder sound.
 
✦
 
In addition to the speaker output jacks, two stereo 
output channels for line-level signals, two monitor 
output channels, one effect output, and one monaural 
output are provided. You can easily expand the system 
by adding a power amplifier or powered speakers.
 
✦
 
The EMX3000 also has a C-R/PHONES jack, which is 
very useful for checking the sound. You can monitor 
only a specific channel or bus signal through the 
headphones.
 
✦
 
Two limiter circuits are built-in to prevent excessive 
input levels to the amp.
 
✦
 
A digital effect with sixteen selectable effect types is 
built-in. A variety of effects can be applied to add 
reverberation or ambience to vocals or instrumental 
sounds.
 
✦
 
The EMX3000 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.
