Precautions
• 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.
• 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.
• This unit has ventilation holes at the rear to prevent the internal temperature rising too high. Do
not block them. Blocked ventilation holes are 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.
• Use only speaker cables when connecting speakers to amplifier outputs. Using other types of
cables 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.
• 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 (-).
• 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.
• Do not modify the unit. Doing so is a fire and
electrical shock hazard.
• When rack-mounting the unit, 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.
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 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: 12 kHz ±15 dB shelving type
MID:
2.5 kHz ±15 dB peaking type
LOW:
80 Hz ±15 dB shelving type
EMX660—Owner’s Manual
For each channel, this controls the amount of signal that is sent to the MONITOR bus.
The signal of the MONITOR bus is sent to the
speakers connected to the POWER AMP 2 A/B
jacks (only if the power amp select switch is in the
MAIN-MONITOR position) and to the MONITOR jacks (input/output panel 6).

2 Monitor controls (MONI)
Note: The signal is sent to the MONITOR bus
from a location before the level control (4) of
each channel. This means that it will not be affected by the setting of the LEVEL control.
3 Effect control (EFFECT)
For each channel, this controls the amount of signal that is sent to the EFFECT bus.
The signal of the EFFECT bus is sent to the builtin effect and to the EFFECT OUT jacks (input/
output panel 3).
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 affected not only by the setting of the effect control, but also by the setting of the level control.
4 Level control (LEVEL)
This adjusts the output level for each channel.
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).

7 DIGITAL EFFECT ON switch and indicator
When this switch is on (pressed), the indicator
lights up and the built-in digital effect can be
used. In that case, the signal processed by the digital effect will be sent to the MAIN/MONITOR
bus. The mix level of the effect sound is adjusted
by the EFFECT RTN control of the MAIN and
MONITOR sections.
This is a 7-band graphic equalizer that allows you
to adjust the frequency response of the MONITOR 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 frequency
bands at which feedback easily occurs. Frequency
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 MONITOR bus signal that is output to the speakers and
the line level signal which is output from the
MONITOR jack (input/output panel 6).

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.
INST 1 & 2 jacks are unbalanced, can be used
simultaneously, and their high input impedance
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. Nominal input
level is –30 dB.
Note: It is possible to simultaneously use both
the MIC and LINE inputs for channel 5, and the
MIC and INST inputs for channel 6.
+
Note: It is not possible to simultaneously use
both the Hi-Z and Lo-Z inputs of a given channel. For each channel, use only one of the inputs
as appropriate for the input source.
Phantom power is switched on/off in simultaneously for the Lo-Z jacks of channels 1–4 and
the MIC jacks of channels 5–6. For this reason,
any devices other than condenser microphones
must be connected to the Hi-Z or LINE jacks if
the PHANTOM switch (control panel L) is on.
EMX660—Owner’s Manual

2 MIC, LINE, INST 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 (synthesizers or rhythm boxes etc.). The Lo-Z jacks can
provide +15 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Lo-Z are balanced, and are compatible with microphones of output impedance
50–600Ω or line level devices of 600Ω. The nominal input level is –40 dB – –10 dB for the Hi-Z
jacks, and –50 dB – –20 dB for the Lo-Z jacks.
Pin connections for the Hi-Z and Lo-Z jacks are
as follows.

make sure that the power of all equipment (where applicable) is turned off.
Also make sure that the level controls of
each channel of the EMX660 and the
MASTER control of the MAIN section are
turned down.
2 Connect cables to your mics and instruments, and insert the other end of the
cable firmly into the appropriate Lo-Z/HiZ jack (channels 1–4) or the MIC jack
(channels 5–6), LINE jack (channels 5),
INST jack (channels 6).
Note: When connecting a line level device to
channels 1–4, turn on the PAD switch.
You cannot use a channel’s Lo-Z and Hi-Z jacks
at the same time. The MIC and LINE jacks, or
the MIC and INST jacks, however, can be used
at the same time.
3 Turn the power on in the order of peripheral devices ➞ EMX660.
Note: When turning the power off, reverse this
sequence.
4 Set the MAIN section MASTER control to
the √ position.
5 While speaking into the mic (while playing the instrument), adjust the channel
LEVEL control so that the 0 LED of the
MAIN section peak level meter lights
occasionally.
Repeat this step for each channel.
6 If you wish to adjust the tone of each
channel, rotate the equalizer controls as
desired.
7 Use the MAIN section graphic equalizer
to adjust the tone.
8 Use the MAIN MASTER control to adjust
the overall volume.
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 MONI controls are not affected by
the LEVEL controls.
1 Set the MONI MASTER control to the √
position.
2 While speaking into a connected mic, or
playing a connected instrument, adjust
the MONI control of the input channel
that you want to monitor.
Repeat this procedure for each channel.
3 Use the MONI MASTER control to set the
overall level of the monitor mix.
Using the digital effect
The EMX660 has a built-in digital effect, allowing reverberation or ambiance to be added to
vocals or instrumental sounds.
1 Press the DIGITAL EFFECT ON switch of
the DIGITAL EFFECT section.
2 Use the effect select switches of the DIGITAL EFFECT section to select the effect
type.
VO.ECHO 1, 2 .....Echo appropriate for vocals.
VO.REV. 1, 2........Reverb appropriate for vocals.
HALL 1, 2 .............Reverb typical of a hall.
ROOM ..................Reverb typical of a room.
PLATE .................Plate echo-like reverberation
3 Set the MAIN EFFECT RTN control to the
√ position.
4 Raise the EFFECT control of the channels
to which you wish to apply the digital
effect.
5 Use the MAIN/MONITOR section EFFECT
RTN control to adjust the level of the
sound processed by the effect.
Note: If the effect sound is distorted even if the
EFFECT RTN turned all the way down, lower
the EFFECT controls of each channel.

As a band PA
15
As a band PA
Here is an example of using the EMX660 as a small PA for a band. In this example, the monitor speakers are
being sent a mix that is independent of the MAIN speaker mix. An external effect such as delay or reverb is
also being used.
Connections
Note: Set the power amp select switch of the POWER AMP section to the “MAIN MONITOR” position. If you are using an external effect, we
recommend that you turn down the EFFECT RTN
controls of the MAIN and MONITOR sections. If
the external effect has a stereo output, it is possible
to connect its output jacks to the LINE jacks of
channels 5. However in this case, be sure that the
EFFECT controls are turned all the way down for
the channels into which the effect sound is being input. If the EFFECT controls are raised, feedback will
occur, and your speakers may be damaged.
• Connect mics or instruments, such as keyboards,
to the channel input jacks 1–6.
• Connect the main speakers to the POWER AMP
1 A/B jacks, and connect the monitor speakers to
the POWER AMP 2 A/B jacks.
• If you will be using an external effect such as
delay or reverb, connect the EMX660’s EFFECT
OUT jack to the input jack of the external effect,
and connect the output jack of the external effect
to the EMX660’s AUX IN jack.

Example setups
Sending an independent mix to the
monitor speakers
1 Set the MONITOR section MASTER control to the √ position.
2 Raise the MONI controls for the channels
that you wish to hear from the monitor
speakers.
Note: The MONI controls are not affected by
the level settings of each channel. This allows
you to create a mix that is independent of the
MAIN section.
3 Use the graphic equalizers and MASTER
controls of the MAIN/MONITOR sections
to adjust the overall volume and tone.
