Important
Read the following before operating the EMX620
Warnings
• Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock
may result.
• 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 scratch, bend, twist, pull, or heat the power cord. A damaged power cord is 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.
Important
3
• If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid
gets inside the unit, turn it off immediately. Remove the power cord from the AC outlet.
Consult your dealer for repair. Using the unit in this condition 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 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.
• 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.
Cautions
• Allow enough free space around the unit for normal ventilation. This should be: 30 cm at the
sides, 30 cm behind, and 40 cm above.
These distances should also be adopted when rack-mounting the unit. 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.
• This unit has ventilation holes at the front, rear and sides to prevent the internal temperature
rising too high. Do not block them. Blocked ventilation holes are a fire hazard.
• Clean phone plugs before plugging them into the speaker jacks of this unit. Dirty contacts
may generate heat.
• Use only designated speaker cables to connect speakers to the amplifier outputs. Using other
types of cable is a fire hazard.
• Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.

Operating Notes
• 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 (–).
• 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.
• 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.
EMX620—Owner’s Manual
Introduction
Thank you for purchasing the Yamaha EMX620 Powered Mixer. In order to take full
advantage of the EMX620 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 EMX620’s six input channels support a wide
range of audio sources, including microphones,
instruments, and line-level devices. Input channels 1 through 4 feature lo- and hi-impedance
balanced inputs, with +15 V phantom powering
for use with condenser-type microphones on the
lo inputs, input channel 5 features two line-level
inputs, while input channel 6 features two
hi-impedance inputs for connecting instruments
such as electric-acoustic guitar and electric bass
directly.
• The built-in power amplifier offers a maximum
output of 200 W with a 4Ω speaker system,
135 W with an 8Ω 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 attenuating troublesome frequencies.

• Also built-in is a digital effects processor, offering
three different programs for adding reverberation 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 stereo recorder (cassette, DAT, or MD).

Channel Section
The channel controls are used to set the EQ,
MONI and EFFECT send levels, channel LEVEL,
and PAD for each channel.

EFFECT control
C
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.
EFFECT bus signals are fed simultaneously to the
onboard effects processor and the EFFECT OUT
jack for use with external effects processors.
The EFFECT control is affected by the channel’s
LEVEL control, since the EFFECT signal is
sourced after that 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, MAIN
output section, and internal power amplifier.
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.
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
MONI control
The MONI control determines the level of the
input signal that is fed to the MONI bus and subsequently the MONITOR OUTPUT jack.
The MONI control is not affected by the channel’s LEVEL control, since the MONI signal is
sourced before that control.
