EMX62M—Owner’s Manual
Introduction
Thank you for purchasing the Yamaha EMX62M Powered Mixer. In order to take full
advantage of the EMX62M and enjoy long and trouble-free operation, read this owner’s
manual carefully, and keep it in a safe place for future reference.
Features
• The EMX62M’s six input channels support a
wide range of audio sources, including micro-
phones, instruments, and line-level devices.
Input channels 1 through 4 feature low- and
hi-impedance balanced inputs, with +15 V phan-
tom power for use with condenser-type micro-
phones on the low inputs, input channel 5
features two line-level inputs, while input chan-
nel 6 features two hi-impedance inputs for con-
necting instruments such as electric-acoustic
guitar and electric bass directly.
• The built-in power amplifier offers a maximum
output of 200 W with a 4
Ω
speaker system,
135 W with an 8
Ω
speaker system, and a limiter
circuit prevents sounds distortion and speaker
damage.
• The 7-band graphic equalizer on the main output
allows you to tailor the sound for each particular
venue and reduce the risk of feedback by attenu-
ating troublesome frequencies.
• Also built-in is a digital effects processor, offering
three different programs for adding reverbera-
tion or ambiance to vocal or instrument sounds,
and remote on/off control using an optional
footswitch.
• External effects can be patched into the system
via the EFFECT OUT and AUX IN jacks, with
effects return level control.
• Separate outputs are provided for connecting
powered monitor speakers, headphones, or a ste-
reo recorder (cassette, DAT, or MD).
• The EMX62M 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
The channel controls are used to set the EQ,
MONITOR and EFFECT send levels, channel
LEVEL, and PAD for each channel.
1
HIGH & LOW EQ controls
The 2-band equalizer allows you to boost or cut
the low or high frequency range for each channel.
The frequency response is flat when the controls
are in the center (
▼
) position. Rotating clockwise
boosts frequencies, rotating counterclockwise
cuts them.
The center frequencies are as follows:
HIGH: 10 kHz ±15 dB shelving type
LOW: 100 Hz ±15 dB shelving type
B
MONITOR control
The MONITOR control determines the level of
the input signal that is fed to the MONITOR bus
and subsequently the MONITOR OUTPUT jack
(input/output panel
0
).
The MONITOR control is not affected by the
channel’s LEVEL control
4
, since the MONI-
TOR signal is sourced before that control.
C
EFFECT control
The EFFECT control determines the level of the
input signal that is fed to the EFFECT bus and
subsequently the onboard effects processor and
EFFECT OUT jack (input/output panel
4
).
EFFECT bus signals are fed simultaneously to the
onboard effects processor and the EFFECT OUT
jack for use with external effects processors.
The EFFECT bus signals are affected by the chan-
nel’s LEVEL control
4
, since the EFFECT signal
is sourced after the EFFECT control. To send a
channel signal to the EFFECT bus, both the
EFFECT and LEVEL controls must be turned up.
D
LEVEL control
The LEVEL control determines the level of the
input signal that is fed to the MAIN bus and
internal power amplifier.
The MAIN bus signal is routed to the MAIN
OUTPUT jack (input/output panel
9
), SPEAK-
ERS 1 and 2 jacks (rear panel
1
), and PHONES
jack (input/output panel
A
).
E
PAD switch (1–4 only)
The PAD switch attenuates the input signal by
30 dB. When connecting a line-level source to
inputs 1 through 4, or if a microphone signal is
distorted, use the PAD switch to attenuate the
input signal.

also contains the LIMITER indicator and main
output level meter.
H
Graphic equalizer
The 7-band graphic equalizer is used to boost or
cut certain frequencies of the MAIN output sig-
nal by up to ±12 dB. It affects the MAIN OUT-
PUT signal, the speaker outputs, and the
PHONES.
I EFFECT RTN control
The MAIN EFFECT RTN control determines the
level of the signal from the built-in digital effects
processor that is fed to the MAIN bus and subse-
quently the MAIN outputs.
J AUX IN control
The AUX IN control determines the level of the
AUX IN signal that is fed to the MAIN bus and
subsequently the MAIN outputs.
K 2TR IN control
The 2TR IN control determines the level of the

1 Hi-Z, Low-Z (inputs 1–4)
These are the input connectors for input chan-
nels 1 through 4.
Both the Hi-Z and Low-Z input can be used with
microphones and, by using the PAD switch (con-
trol panel 5), can also be used with line-level
sources, such as synthesizers and drum machines.
Switchable +15 V phantom power is available to
the Low-Z XLR-type input for use with con-
denser-type microphones.
Both the Hi-Z and Low-Z inputs are balanced.
Pin connections are as follows.
B LINE 1 & 2 (input 5)
These two phone jacks are the input connectors
for input channel 5. They are unbalanced, can be
used simultaneously, and are appropriate for use
with line-level sources, such as synthesizers and
drum machines.
C Super Hi-Z 1 & 2 (input 6)
These two phone jacks are the input connectors
for input channel 6. They 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.
D EFFECT OUT jack
The EFFECT OUT phone jack outputs the signal
from the EFFECT bus and can be connected to
the input of an external effects processor.
E FOOT SW jack
The FOOT SW jack is used to connect an
optional footswitch, such as the Yamaha FC5,
which can be used to turn the built-in digital
effects processor on and off. The DIGITAL
EFFECT ON switch must be in the ON position
in order to use the footswitch.
F AUX IN—INPUT TO MAIN jack
The AUX IN—INPUT TO MAIN phone jack is
used to feed signals from an external source to
the MAIN bus and can be connected to the out-
put of an external effects processor, for example.
G 2TR IN—INPUT TO MAIN jacks
The 2TR IN—INPUT TO MAIN phono jacks are
used to feed signals from an external source to
the MAIN bus and can be connected to the stereo
outputs of a cassette, DAT, or MD deck.
H REC OUT—OUTPUT jacks
The REC OUT—OUTPUT phono jacks output
the MAIN bus signal prior to the 7-band graphic
equalizer and MASTER level control, and can be
connected to the stereo inputs of a cassette, DAT,
or MD deck for recording.

Basic Operation
Connecting Sources
Before connecting any microphones or instru-
ments, make sure that the EMX62M and any
other applicable equipment is turned off. Also
make sure that the LEVEL control on each
EMX62M input channel, and the MAIN MAS-
TER and MONITOR MASTER controls are
turned down.
1 Connect cables to your mics and instru-
ments, and insert the other end of the
cables firmly into the appropriate Low-Z
or Hi-Z jack (channels 1–4), LINE jack
(channel 5), or Super Hi-Z jack
(channel 6).
B Turn on the power, starting with the
sound sources and finishing with the
EMX62M.
Reverse this order when turning off the power.
C Set the MAIN MASTER control to the “√√
√√

the 0 LED of the MAIN section level meter
lights occasionally.
Repeat this procedure for each channel.
E Use the EQ controls on each input chan-
nel to adjust the tonal characteristics of
each source.
F Use the 7-band graphic equalizer to
adjust the tonal characteristics of the
main output.
G Use the MAIN MASTER control to set the
overall volume level of the main mix.
Monitoring
By connecting a powered monitor speaker to the
MONITOR OUTPUT, you can create a monitor
mix independent of the MAIN mix, since the
input channel MONITOR controls are not
affected by the LEVEL controls.
1 Set the MONITOR MASTER control to the
“√√

EMX62M—Owner’s Manual
Installing an optional rack mount kit
You can rack-mount the EMX62M using an
optional rack mount kit (RK-88).
Rack mount kit RK-88
•Bracket × 2
• Screw × 6
Before you rack-mount the EMX62M, make sure
that sufficient ventilation will be maintained.
(Never install the unit in a sealed rack.)
If you are going to install multiple devices includ-
ing the unit in a rack, keep a 1U space or more
between the devices. Use a blank panel with holes
for ventilation if you wish to insert a panel
between the devices.
You will need a 7U space to install the rack
mount. After installation, the unit will project
62 mm from the front surface of the rack.
Installing the rack mount bracket
1 Remove the carrying handle by loosening and
removing four screws.

18 Troubleshooting
EMX62M—Owner’s Manual
Troubleshooting
The following table describes the possible malfunctions of this demvice, and the appropriate actions to be
taken in each case.
Powered Mixer Q&A
Problem Cause Action
Sound is no
longer out-
put from the
speakers.
The POWER
indicator is lit.
The load on the amplifier of this
device was too great, and
the protec-
tion circuit for the amplifier
has
operated. Possible reasons for the
excessive load are an excessive level
setting in the channel control section
or main section, insufficient ventila-
tion, or insufficient load impedance
of the connected speakers.
Please wait. When the device cools off, normal operation
will resume automatically. However, please check the fol-
lowing three points to prevent the problem from recurring.
• If the level setting is excessive, lower it to the nominal
level. You can refer to the peak level indicators of the
main section when doing so.
• If the device is not ventilated sufficiently, refer to the cau-
tions given at the beginning of this manual and take
appropriate measures to insure adequate ventilation.
• If the load impedance (including a short) is too low, refer
to the section on rear panel (page 14) and change the
connections so that the impedance is correct.
Other
Connections between devices have
come loose.
Inspect the connections, and correct any faulty connec-
tions.
Other The device may have malfunctioned. Please contact your
dealer.
Unbalanced
sound out-
put from the
speakers
No high range
is heard from
the speakers.
The speaker’s protection circuit has
been activated due to excessive input
signals.
Turn off the power to the EMX62M, or lower the volume
level. The EMX62M will return to its normal operation in
several seconds. Then, turn on the power to the unit or
raise the volume level and check to see if the high range is
audible. Maintain the level so that the protection circuit
will not be activated.
Q:
The built-in effect is not effective.
A:
The ON switch in the DIGITAL EFFECT section may not be
turned on. Or, you have adjusted the EFFECT control in the
Channel section or the MAIN EFFECT RTN control.
Q:
The monitoring sound from the speakers is not powerful
enough relative to the level of the input sound.
A:
The equalizer LOW control for each channel may be set to
negative values.
Q:
The stereo output from the synthesizer has been routed
to the Super Hi-Z jack of channel 6, but the monitoring
sound is not stereo.
A:
You can use Super Hi-Z (or LINE) 1 and 2 jacks at the same
time.
However, they are internally routed into a mono channel, and
therefore the signals from 1 and 2 jacks are output as mono
signal.
Q:
The signal is sent from the EFFECT OUT jack to the
connected effect processor. Then the effect sound is
returned to the AUX IN jack. However, no signal is input
to the mixer.
A:
The AUX IN control in the MAIN section may not be rotated to
right.
Q:
An external powered speaker is connected to the MON-
ITOR-OUTPUT jack.
However, the signal is not sent to the speaker even
when the MASTER control in the MONITOR section is
turned.
A:
The MONITOR controls for input channels may not have been
adjusted.
Q:
Can the Low-Z jack and the Hi-Z jack be used at the
same time?
A:
You cannot use the Low-Z jack and the Hi-Z jack for the same
channel at the same time.
Q:
Can a single speaker be connected to the mixer?
A:
Yes. Use a speaker with an impedance of 4-8 ohms.
