PRECAUTIONS
PLEASE READ CAREFULLY
BEFORE PROCEEDING
Please keep this manual in a safe place for
future reference.
WARNING
Always follow the basic precautions listed below to
avoid the possibility of serious injury or even death
from electrical shock, short-circuiting, damages, fire or
other hazards. These precautions include, but are not
limited to, the following:
Power supply/AC power adaptor
Do not place the power cord near heat sources such as
heaters or radiators, and do not excessively bend or
otherwise damage the cord, place heavy objects on it, or
place it in a position where anyone could walk on, trip over,
or roll anything over it.
Only use the voltage specified as correct for the device. The
required voltage is printed on the name plate of the device.
Use the specified adaptor only. Using the wrong adaptor
can result in damage to the device or overheating.
Check the electric plug periodically and remove any dirt or
dust which may have accumulated on it.
When setting up the device, make sure that the AC outlet
you are using is easily accessible. If some trouble or
malfunction occurs, immediately turn off the power switch
and disconnect the plug from the outlet. Even when the
power switch is turned off, as long as the power cord is not
unplugged from the wall AC outlet, the device will not be
disconnected from the power source.
Remove the electric plug from the outlet when the device is
not to be used for extended periods of time, or during
electrical storms.
Do not open
This device contains no user-serviceable parts. Do not open
the device or attempt to disassemble the internal parts or
modify them in any way. If it should appear to be
malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
Water warning
Do not expose the device to rain, use it near water or in
damp or wet conditions, or place on it any containers (such
as vases, bottles or glasses) containing liquids which might
spill into any openings. If any liquid such as water seeps
into the device, turn off the power immediately and unplug
the power cord from the AC outlet. Then have the device
inspected by qualified Yamaha service personnel.
Never insert or remove an electric plug with wet hands.
Hearing loss
Avoid setting all equalizer controls and faders to their
maximum. Depending on the condition of the connected
devices, doing so may result in feedback that can cause
hearing loss and damage the speakers.
Do not use headphones for a long period of time at a high or
uncomfortable volume level, since this can cause
permanent hearing loss. If you experience any hearing loss
or ringing in the ears, consult a physician.
Before connecting the device to other devices, turn off the
power for all devices. Also, before turning the power of all
devices on or off, make sure that all volume levels are set to
the minimum. Failing to do so may result in hearing loss,
electric shock, or device damage.
When turning on the AC power in your audio system, always
turn on the power amplifier LAST, to avoid hearing loss and
speaker damage. When turning the power off, the power
amplifier should be turned off FIRST for the same reason.
Fire warning
Do not place any burning items or open flames near the
device, since they may cause a fire.
If you notice any abnormality
If any of the following problems occur, immediately turn off
the power switch and disconnect the electric plug from the
outlet.
- The power cord or plug becomes frayed or damaged.
- Unusual smells or smoke are emitted.
- Some object has been dropped into the device.
- There is a sudden loss of sound during use of the device.
- Cracks or other visible damage appear on the device.
Then have the device inspected or repaired by qualified
Yamaha service personnel.
If this device or the AC power adaptor should be dropped
or damaged, immediately turn off the power switch,
disconnect the electric plug from the outlet, and have the
device inspected by qualified Yamaha service personnel.
CAUTION
Always follow the basic precautions listed below to
avoid the possibility of physical injury to you or others,
or damage to the device or other property. These
precautions include, but are not limited to, the
following:
Power supply/AC power adaptor
Do not cover or wrap the AC power adaptor with a cloth or
blanket.
When removing the electric plug from the device or an
outlet, always hold the plug itself and not the cord. Pulling
by the cord can damage it.
Location
Do not place the device in an unstable position where it
might accidentally fall over and cause injuries.
Do not place the device in a location where it may come into
contact with corrosive gases or salt air. Doing so may result
in malfunction.

Handling caution
Do not rest your weight on the device or place heavy
objects on it. Avoid applying excessive force to the buttons,
switches or connectors to prevent injuries.
Avoid pulling the connected cables to prevent injuries or
damage to the device.
NOTICE
To avoid the possibility of malfunction/damage to the product, damage to data, or damage to other property, follow the notices
below.
Handling and maintenance
Do not use the device in the vicinity of a TV, radio, AV equipment, mobile phone, or other electric devices. Otherwise, the
device, TV, or radio may generate noise.
Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or
in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the inter-
nal components.
Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel.
When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impreg-
nated wiping cloths.
Condensation can occur in the device due to rapid, drastic changes in ambient temperature—when the device is moved
from one location to another, or air conditioning is turned on or off, for example. Using the device while condensation is
present can cause damage. If there is reason to believe that condensation might have occurred, leave the device for several
hours without turning on the power until the condensation has completely dried out.
To avoid generating unwanted noise, make sure there is adequate distance (50cm or more) between the AC adaptor and
the device.
Do not apply oil, grease, or contact cleaner to the knobs. Doing so may cause problems with electrical contact or knob
motion.
Always turn the power off when the device is not in use.
Even when the power switch is in standby status, electricity is still flowing to the device at the minimum level. When you are
not using the device for a long time, make sure you unplug the power cord from the wall AC outlet.

Main Features
D-PRE and High-Quality Operational Amplifiers
Mono input channels are equipped with “D-PRE” Class-A discrete microphone preamplifiers. The D-PRE head ampli-
fier features an inverted Darlington circuit used in high-end audio devices. This circuit uses multi-stage amplifying ele-
ments to ensure high current and low impedance, for an audio texture with crispness and richness in the low and mid
frequencies. Combined with the specially-designed “MG01” operational amp, the overall result is full-bodied reproduc-
tion of low frequencies as well as sustained high frequencies. Input channels feature combo jacks, which can accept
both XLR and TRS connectors. In addition, PAD circuitry allows line level input, to accommodate a wide variety of
instruments.
24 High-Quality Digital Effects

Other
If any specific problem should persist, please contact your Yamaha dealer.
The power does not come on. Is the mixer connected to an independent power source (generator, etc.) or a power strip
with switches?
Check that the power of that device is turned on.
No sound is output. Are external instruments (including microphones) and speakers connected correctly?
Are your cables shorted?
Are the [GAIN] knobs for each channel, [LEVEL] knobs, [STEREO LEVEL] knob adjusted to
appropriate levels?
Are the[LINE /USB ] switch set appropriately?
The sound is low, distorted, or
noisy.
Is the microphone connected to a [MIC/LINE] jack?
When using a condenser microphone, is the [PHANTOM +48V] switch turned on?
Is the [PAD] switch on?
Turn this switch off for sources with low output levels, such as microphones.
Is the output signal level for the instrument connected to the mixer appropriate?
When connecting an instrument with an output level of +4 dBu, either turn on the [PAD]
switch on a mono input channel or use a stereo input channel.
Where an input channel provides both a XLR input jack and a phone input jack, or a phone
input jack and an RCA pin jack, are there connections made at both jacks?
Use only one of these jacks.
Are the [GAIN] knobs for each channel, [LEVEL] knobs, [STEREO LEVEL] knob adjusted to
appropriate levels?
Are effect or compressor levels too high?
Use the [FX] knobs, [FX RTN LEVEL] knob, and [COMP] knobs to lower their levels.
Effects are not applied. Are the [FX] knobs for each channel adjusted to appropriate levels?
Is the [FX ON] button for [FX RTN] turned on?
Are the [PARAMETER] knob and [FX RTN LEVEL] knob adjusted to appropriate levels?
Speaking voices are not clear. Is the [HPF] switch turned on?
Is the equalizer ([HIGH]/[MID]/[LOW]) adjusted appropriately?
No mixer monitor signal is output. Are powered speakers connected to the [MONITOR OUT] jacks?
Use the [MONITOR/PHONES] knob to adjust the signal output from the [MONITOR OUT]
jacks.
Left and right levels are different
for a stereo signal input.
Is [PAN] set to the center?
If panned to the center, try reversing the left and right input connections. If, after switching
the left and right connections, the side with the low volume level also switches, check the
instrument or device that is the source of the signal.
Are you using the same type of cable to connect both the left and right input signals?
Cables with built-in resistors will attenuate the signal.
The sound level is unstable and
inconsistent.
Is the compressor level set too high?
Use the [COMP] knob to lower the level.
The volume of audio play-back
from a computer need to be
