Block and Level diagram
Power Amplifier output section level diagram (bottom right)
These plots show the nominal output and maximum output
levels of signals received at the SPEAKERS jacks. If the output
level is +4dB (Level Meter “0”), the internal power amplifier
will deliver 60W into a 4
Ω
load. If the output level is +11dB
(LIMITER indicator lights), the internal amplifier will deliver
a maximum of 300W into a 4
Ω
load. If you are using the
BRIDGE jack, the internal power amplifier will deliver 120W
into an 8
Ω
load with a +4dB signal, and a maximum of 600W
into an 8
Ω
load with a +11dB signal.
E
Note:
The SPEAKERS 1 & 2 jacks (rear panel
1
) out-
put the signals received at the MAIN OUT jack via the
internal power amplifier. Check the output signal level
via the LIMITER indicator (
I
).
Note:
The SPEAKERS 1 & 2 jacks (rear panel
1
) out-
put the signals received at the MONITOR OUT jack via
the internal power amplifier. Check the output signal
level via the LIMITER indicator (
I
).
Caution:
If the LIMITER indicator flashes continuous-
ly, the internal power amplifier section is being exces-
sively overloaded and may malfunction. Reduce the
output level at the Master control (
BG
) below the level
that the indicator flashes only briefly on the highest
transient peaks.

EMX66M—Owner’s Manual
Precautions
WARNING
• 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. Liquid 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.
• The power to this device is not completely shut off even when
the power switch is turned off. Locate the device close to the AC
outlet so you can easily reach the power plug.
• Use only the included power cord for this unit. Using other
types may be a fire and electrical shock hazard.
• 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.
• 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

tial 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 venti-
lation 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.
• Use only speaker cables when connecting speakers to amplifier
outputs. Using other types of cables is a fire hazard.
• Clean the contacts of the phone plug before connecting it to the
SPEAKERS jack of this unit. Dirty contacts may generate heat.
• XLR-type connectors are wired as follows: pin 1: ground, pin 2:
hot (+), and pin 3: cold (-).
• 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.
• Using a cell phone (mobile telephone) near this unit may induce
noise. If noise occurs, use the telephone away from the unit.
• 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.

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.

■
Channel section
In this section, you can adjust equalization (fre-
quency response), volume level, effect and moni-
tor output levels for the input signal of each
channel.
1
Equalizer controls (HIGH, MID, LOW)
This is a 3-band equalizer that adjusts the high
frequency range, mid frequency range, and low
frequency range of each channel. Response is flat
when the knobs are in the “
▼
” position. Rotating
it toward the right will boost the corresponding
frequency band, and rotating it toward the left
will cut it.
The base frequency (or center frequency), range
of boost or cut, and equalizer type of each band
are as follows.
HIGH: 10 kHz ±15 dB shelving type
MID: 2.5 kHz ±15 dB peaking type
LOW: 100 Hz ±15 dB shelving type
2
Monitor control (MONITOR)
For each channel, this controls the amount of sig-
nal that is sent to the MONITOR bus.
The signal of the MONITOR bus is sent to the
speakers connected to the SPEAKERS B 1/2 jacks
(only if the power amp select switch is in the
MAIN-MON position) and to the MONITOR
jacks (input/output panel
6
).
3
Effect control (EFFECT)
For each channel, this controls the amount of sig-
nal that is sent to the EFFECT bus.
The signal of the EFFECT bus is sent to the built-
in effect and to the EFFECT OUT jacks (input/
output panel
3
).
4
Level control (LEVEL)
This control adjusts the level of signals routed
from each channel to the MAIN bus and to the
built-in power amplifier.
The MAIN bus signal is sent to the MAIN jacks
(input/output panel
6
) and the SPEAKERS jacks
on the rear panel
1
.
5
Pad switch (PAD) (Channel 1–4 only)
This switch attenuates the input signal by 30 dB.
When connecting a line level device to channels
1–4, or if the mic input is distorted, turn this
switch on (the pressed-in position).

Note:
The signal is sent to the MONITOR bus
from a location before the level control (

each channel. This means that it will not be af-
fected by the setting of the LEVEL control.
Note:
The signal is sent to the EFFECT bus
from a location after the level control (
4
) of
each channel. This means that the amount of
signal that is sent to the EFFECT bus will be af-
fected not only by the setting of the effect con-
trol, but also by the setting of the level control.

■ MONITOR section
This section allows you to adjust the tone and
volume of the MONITOR bus, and specify the
mix level of the built-in effect and the external
input signals.
D Graphic equalizer
This is a 7-band graphic equalizer that allows you
to adjust the frequency response of the MONI-
TOR bus signal, providing a maximum of ±12 dB
of cut/boost for each frequency band.
You can use these sliders to reduce the level of fre-
quency bands at which feedback easily occurs. Fre-
quency response is flat when a slider is in the center
position. Moving a slider in the positive direction
will boost, and in the negative direction will cut.
This graphic equalizer affects both the MONI-
TOR bus signal that is output to the speakers and
the line level signal which is output from the
MONITOR jack (input/output panel 6).
E EFFECT RTN control
This controls the level of the effect sound which
is returned from the built-in digital effect to the
MONITOR bus.
F 2TR IN control
This controls the level of the signal routed from
the 2TR IN jack (input/output panel 5) to the
MONITOR bus.
G MASTER control
This adjusts the final level of the MONITOR bus.
It affects both the MONITOR bus signal which is
output to the speakers and the line level signal
which is output to the MONITOR jack (input/
output panel 6).
H Peak level indicator
This indicator allows you to monitor the level of
the signal which is output from the MONITOR
jack (input/output panel 6).
■ POWER AMP section
This section allows you to select the signals that
will be input to the built-in two-channel power
amplifier.
I LIMITER indicator
This indicator lights up when the level of the sig-
nal output from the power amp section reaches
the maximum and the limiter is activated. Adjust
appropriate control so that the indicator lights up
for only a short while when the signal reaches the
maximum level.
J Power amp select switch
Select one of the following three settings to route
the signals to the appropriate jacks, depending on
the speaker connection at the SPEAKERS jacks
(rear panel 1).
• MAIN-MON
With this setting, the MAIN bus signal will be
output from the SPEAKERS A 1/2 jacks and the
MONITOR bus signal is output from the
SPEAKERS B 1/2 jacks. The MASTER controls
(B, G) in the MAIN and MONITOR sections
are both effective.
• MAIN-MAIN
With this setting, the MAIN bus signal will be
output from the SPEAKERS A 1/2 jacks and
from the SPEAKERS B 1/2 jacks. Only the MAS-
TER control B in the MAIN section becomes
effective.
• MAIN BRIDGE
With this setting, the MAIN bus signal will be
output from the BRIDGE jack. The two power
amp channels will be bridge connected. Only the

1 Hi-Z, Low-Z input jacks
These are the input jacks for channels 1–4.
By using the PAD switches (control panel 5) you
can connect any of the jacks to a wide range of
sources from mics to line level devices (synthesiz-
ers or rhythm boxes etc.). The Low-Z jacks can
provide +15 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Low-Z are balanced, and are com-
patible with microphones of output impedance
50–600Ω or line level devices of 600Ω. The nom-
inal input level is –40 dB – –10 dB for the Hi-Z
jacks, and –50 dB – –20 dB for the Low-Z jacks.
Pin connections for the Hi-Z and Low-Z jacks are
as follows.
2 MIC, LINE, Super Hi-Z input jacks
These are the input jacks for channels 5–6.
Microphones can be connected to the MIC jacks,
and stereo line level devices (such as synthesizers
or rhythm boxes) can be connected to the LINE
jacks.
The MIC jacks are balanced, and are compatible
with microphones of output impedance 50–
600Ω.
The LINE 1 & 2 jacks are unbalanced, and are
compatible with line level devices of 600Ω output
impedance. These two input jacks can be used
simultaneously.
Nominal input level is –50 dB for the MIC jacks
and –10 dB for the LINE jacks.
Super Hi-Z 1 & 2 jacks are unbalanced, can be
used simultaneously, and their high input imped-
ance makes them ideal for use with instruments
such as electric-acoustic guitar and electric bass.
They can also be used with line-level sources,
such as synthesizers and drum machines. Nomi-
nal input level is –30 dB.
3 Effect output jack (EFFECT OUT)
The input of an external effect such as a delay or
echo can be connected to this jack.
The signal adjusted by the EFFECT control (con-
trol panel 3
)
of each channel will be sent to the
EFFECT bus, and output from this jack.
The nominal output level and conforming
impedance are +4 dB/10 kΩ.

switch the built-in digital effect on/off.
5 AUX IN/2TR IN—INPUT TO MAIN jacks
These are input jacks that allow the signal from
an external device to be added to the MAIN out-
put. Monaural output devices such as external
effects can be connected to the AUX IN jack, and
stereo output devices such as cassette recorder or
CD players can be connected to the 2TR IN jacks.
The nominal input level and impedance are –10 dB/
600Ω for the AUX IN jack, and –10 dBV/600Ω for
the 2TR IN jacks.
6 REC OUT/MAIN/MONITOR—OUTPUT jacks
These are output jacks which send line level sig-
nals from the EMX66M to external devices.
A stereo recording device such as a cassette deck,
DAT or MD recorder can be connected to the
REC OUT jacks, and a playback device such a
power amp can be connected to the MONITOR
and MAIN jacks. The signals sent from each jack
are as follows.
• REC OUT jacks: The MAIN bus signal before it
has passed through the MASTER control and
graphic equalizer
• MAIN jack: The MAIN bus signal which has
passed through the Main MASTER control and
graphic equalizer
• MONITOR jack: The MONITOR bus signal
which has passed through the Monitor MAS-
TER control and graphic equalizer
The nominal output level and impedance are
–10 dBV/10 kΩ for the REC OUT jacks, and
+4 dB/10 kΩ for the MONITOR/MAIN jacks.

top of the rear panel to avoid blocking the heated air flow.
Connection
When connecting various devices, be sure to use cables and plugs of the appropriate standard.
Use dedicated speaker cables to connect the speakers to the speaker jacks.
Speaker connection
There are three ways in which speakers can be connected to the EMX66M.
The speaker impedance requirement varies depending on how you connect the speakers. Refer to the dia-
grams below to make sure the speaker impedance will not be lower than the specified value.
■ When the power amp select switch is set to MAIN-MON or MAIN-MAIN:
• Two-channel connection
Two 4-8Ω speakers can be connected to either SPEAKERS jack 1 or jack 2 of channels A and B. If you are
using speakers rated at 4Ω, the maximum output would be 300W + 300W.
• Two-channel parallel connection
Two 8-16Ω speakers can be connected to both SPEAKERS jack 1 and jack 2 of channels A and B. If you are
