maintenance to qualified Yamaha service personnel. Opening
the case and/or tampering with the internal circuitry voids
the warranty.
5. Always power off before making connections
Always turn the power OFF before connecting or
disconnecting cables. This is important to prevent damage to
the unit itself as well as other connected equipment.
6. Handle cables carefully
Always plug and unplug cables — including the AC power
cord — by gripping the connector, not the cord.
7. Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the
unit. Wipe clean with a soft, dry cloth.
8. Always use the correct power supply
Make sure that the power supply voltage specified on the rear
panel matches your local AC mains supply. Also make sure
that the AC mains supply can deliver more than enough
current to handle all equipment used in your system.
9. Do not touch the heatsink when the EMX640 is in use.
It can get very hot.
Precautions
1. Avoid excessive heat, humidity, dust and vibration
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity — such as near
radiators, stoves, etc. Also avoid locations which are subject
to excessive dust accumulation or vibration which could
cause mechanical damage.
2. Ventilation
Allow a distance of 30 cm between the unit and the wall so
that heat generated from the unit will be released effectively.
Also, allow enough space between the unit and other devices.
If you mount the unit in an audio rack, keep a space of 40
cm on the top panel, and a space of 15 cm to the side panel.
Remove the rear panel of the rack or open a vent hole. If heat
release is inadequate, the unit will retain heat inside the unit,
which may cause a fire.
3. Avoid physical shocks
Strong physical shocks to the unit can cause damage. Handle
it with care.
4. Do not open the case or attempt repairs or modifications
yourself

Features
• Six input channels compatible with mic/line signals are
provided. The EMX640 has ample power, with a maximum
output of 200 W+200 W (400 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 section. This allows the
volume and frequency response to be adjusted separately for
the main speakers and monitor speakers.
• Two limiter circuits are built-in to prevent excessive input
levels to the amp.
• A digital effect with three selectable effect types is built-in.
A variety of effects can be applied to add reverberation or
ambiance to vocals or instrumental sounds.

■
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 fre-
quency 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
2
Monitor controls (MONI)
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 POWER AMP 2 A/B
jacks (only if the power amp select switch is in the
MAIN+MONITOR position) and to the MONI-
TOR 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 passes through the
EFFECT section and the built-in effect, and is
sent to the external effect device connected to the
EFFECT OUT jacks (input/output panel
3
).
4
Level control (LEVEL)
This adjusts the output level for each channel.
5
Pad switch (PAD) (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 (
4
) of
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.

When this switch is on (pressed), the digital effect
built into the EMX640 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 sec-
tions.

EFFECT section
This section allows you to adjust the level of the
signal sent from the EFFECT bus to an external
effect device.
