Troubleshooting

Troubleshooting

Power does not turn on

• Is the included power cord correctly connected to a power outlet?

Power shuts down suddenly

• Is the volume set at high for an extended period of time?

If the mixer is used at a volume beyond the permissible level, the protection circuit automatically turns the

power off. Turn on the power again only after the mixer cools, since it cannot be turned on until the internal

temperature goes down. Reduce the volume with the MASTER LEVEL control so that the LIMITER indicator

flashes only briefly in response to the highest transient peaks.

• Is the vent on the top panel of the mixer blocked?

Since inadequate ventilation can result in overheating the mixer, the protection circuit may come on

automatically and the power may be turned off. Turn on the power again only after the mixer cools, since it

cannot be turned on until the internal temperature goes down.

No sound is heard

• Are external instruments (including a microphone) or speakers correctly connected to the mixer?

• Are the LEVEL controls of all relevant channels and/or the MASTER LEVEL control set to appropriate levels?

• Is the SPEAKER jack connected to the included speaker (300S)?

• Is the POWER indicator flashing? There may be a short in the speaker cable or the connection may be

faulty. Check that the speaker cable is correctly connected to the mixer and reapply the power.

• Is the CLICK switch (for headphones) set to OFF?

• If sound is not still output, contact your Yamaha dealer.

Sound is distorted or noise is produced

• Are the LEVEL controls of all relevant channels and/or the MASTER LEVEL control set to appropriate levels?

• Are the MIC/LINE switches of each channels set appropriately?

• Are both XLR type and phone type jacks on channels 1–2 being used (connected) at the same time?

Please connect to only one of these jacks on each channel.

• Is the input signal from the connected device set to an appropriate level?

Sound is not loud enough

• Are the LEVEL controls of all relevant channels and/or the MASTER LEVEL control set to appropriate levels?

• Are the MIC/LINE switches of each channels set appropriately?

• Are both XLR type and phone type jacks on channels 1–2 being used (connected) at the same time?

Please connect to only one of these jacks on each channel.

• Is the input signal from the connected device set to an appropriate level?

Reverb is not applied to the sound

• Are the REVERB switches of each channels set to ON ( )?

• Is the REVERB control set to an appropriate level?

Getting a more powerful sound from the speakers

• Is the SPEECH/MUSIC switch set to MUSIC ( )?

• Are the Equalizer controls (HIGH/LOW) set to appropriate levels?

Getting a clearer sound for announcements

• Is the SPEECH/MUSIC switch set to SPEECH ( )?

• Are the Equalizer controls (HIGH/LOW) set to appropriate levels?

Outputting the signal to a main mixer

• Connect a main mixer to the ST SUB OUT jack. The ST SUB OUT jack outputs the signal prior to routing

through the MASTER LEVEL control. Adjust the level of output signal from the ST SUB OUT jack with the ST

SUB OUT control. The ST SUB OUT control does not affect the MASTER LEVEL control. If only the L (left)

ST SUB OUT jack is used, the mixer mixes the left and right signals and sends them to the jack.

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/Power cord

• Only use the voltage specified as correct for the device. The required
voltage is printed on the name plate of the device.

• Use only the included power cord.

• 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.

• Be sure to connect to an appropriate outlet with a protective grounding
connection. Improper grounding can result in electrical shock.

Do not open

• Do not open the device or attempt to disassemble the internal parts or
modify them in any way. The device contains no user-serviceable parts.
If it should appear to be malfunctioning, discontinue use immediately and
have it 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/Power cord

• Remove the electric plug from the outlet when the device is not to be used
for extended periods of time, or during electrical storms.

• 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

• Before moving the device, remove all connected cables.

• 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, electricity is still flowing to the product at
the minimum level. When you are not using the product for a long time,
make sure to unplug the power cord from the wall AC outlet.

• Do not use the device in a confined, poorly-ventilated location. Make sure
that there is adequate space between the mixer and surrounding walls or
other devices: at least 30 cm at the sides, 30 cm behind and 30 cm
above. If the mixer is to be used installed into the speaker cabinet, make
sure to allow adequate space between the speaker and the surrounding
walls or other devices: at least 30 cm at the sides, 30 cm behind and 30
cm above. Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even fire.

• Do not use the speaker's handles for suspended installation. Doing so
can result in damage or injury.

• Avoid setting all equalizer controls and faders to their maximum.
Depending on the condition of the connected devices, doing so may
cause feedback and may damage the speakers.

• Do not expose the device to excessive dust or vibrations, or extreme cold
or heat (such as in direct sunlight, near a heater, or in a car during the
day) to prevent the possibility of panel disfiguration or damage to the
internal components.

• Do not place the device in an unstable position where it might
accidentally fall over.

• Do not block the vents. This mixer has ventilation holes at the top to
prevent the internal temperature from becoming too high. In particular, do
not place the device on its side or upside down. Inadequate ventilation
can result in overheating, possibly causing damage to the device(s), or
even fire.

• Do not use the device in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Doing so may result in noise,
both in the device itself and in the TV or radio next to it.

Connections

• Before connecting the device to other devices, turn off the power for all
devices. Before turning the power on or off for all devices, set all volume
levels to minimum.

• For the SPEAKER jack, use only the included speaker (300S) and speaker

conditions, or place containers on it 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.

If you notice any abnormality

• If the power cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the device, or if any unusual smells
or smoke should appear to be caused by it, immediately turn off the
power switch, disconnect the electric plug from the outlet, and have the
device inspected by qualified Yamaha service personnel.

• If this device 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.

Handling caution

• When turning on the AC power in your audio system, always turn on the
device LAST, to avoid speaker damage. When turning the power off, the
device should be turned off FIRST for the same reason.

• Do not insert your fingers or hands in any gaps or openings on the device
(vents,, ports, etc.).

• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.)
into any gaps or openings on the device (vents, ports, etc.) If this
happens, turn off the power immediately and unplug the power cord from
the AC outlet. Then have the device inspected by qualified Yamaha
service personnel.

• Do not use the device or 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.

• Do not operate the device if the sound is distorting. Prolonged use in this
condition could cause overheating and result in fire.

• Do not rest your weight on the device or place heavy objects on it, and
avoid use excessive force on the buttons, switches or connectors.

Interference From Cell Phones

Using a cell phone near the speaker system can induce noise. If this occurs,
move the cell phone further away from the speaker system.

Air blowing out of the bass reflex ports is normal, and often occurs when the
speaker is handling program material with heavy bass content.

Yamaha cannot be held responsible for damage caused by improper use
or modifications to the device.

Always turn the power off when the device is not in use.

The performance of components with moving contacts, such as switches,
volume controls, and connectors, deteriorates over time. Consult qualified
Yamaha service personnel about replacing defective components.

This outputs the mixed signal channels from 1 to

7/8, and the level is adjusted with the PHONES

control. Connect a set of headphones here.

ST SUB OUT L (MONO) / R jacks

These output the mixed signal channels from 1 to

7/8, and the level is adjusted with the ST SUB OUT

control. You can use these jacks, for example, to

connect a main mixer. These impedance balanced

jacks allow a longer cable to be connected with the

use of a balanced cable.

¡ POWER indicator

This lights when the POWER switch

is ON. When the indicator flashes,

the protection circuit is operating.

Check that the speaker cable is

correctly connected to the mixer

and reapply the power.

ST SUB OUT control

Determines the signal level output from the ST SUB

OUT jacks.

NOTE: The MASTER LEVEL control does not affect

the signal via the ST SUB OUT control.

8

PHONES control

Determines the signal level output from the

PHONES jack.

NOTE: The MASTER LEVEL control does not affect

the signal via the PHONES control.

9 Channel input jacks (CH 1, 2)

For connecting a guitar, microphone, keyboard or other instrument/device. Set the MIC/LINE switch to MIC

or LINE for channels 1, 2, depending on the level of the input signal.

XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).

NOTE: On any given channel, you may use either XLR or phone jack, but not both. Please connect to only one of

these jacks on each channel.

) Stereo channel input jacks (CH 3/4, 5/6, 7/8)

Input the left and right channels of a stereo signal into the respective odd and even channels of the mixer.

These inputs are intended mainly for use with instruments and equipment having stereo outputs, such as a

synthesizer or CD player.

NOTE: The channel 7/8 input provides two sets of jacks—both phone jacks and RCA-pin jacks. Either one of these

jacks may be used, but not both at the same time. Please connect to only one of these jacks on each
channel.

! MIC/LINE switch

Set this switch to MIC or LINE for channels 1, 2, depending on the level of the input signal. For low-level

signals (such as that of microphones), set the switch to the MIC ( ) position. For high-level signals (such

as keyboard instruments and audio equipment), set the switch to the LINE ( ) position.

To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before setting

Caution

this switch to MIC or LINE. We also recommend that you turn the MASTER LEVEL control to the

minimum setting before operating the switch, to avoid excessively loud noises that could cause

hearing loss or device damage.

@ Equalizer

HIGH:

Determines the level of the high frequency band for each channel. Rotating the knob

clockwise boosts the high frequencies and produces a clearer, crisper sound. If you start getting

feedback (a high-pitched squealing sound) or you want to make the sound softer and less harsh,

turn the knob counterclockwise slightly.

LOW:

Determines the level of the low frequency band for each channel. Rotating the knob

clockwise boosts the low frequencies and produces a deeper, warmer sound. If you start getting

feedback or you want to make the sound less boomy, turn the knob counterclockwise slightly.

While playing your instrument or singing into the microphone, adjust the

6

LEVEL control of the corresponding channel.

Adjust the LEVEL Control of the corresponding channel so that the “0” LED lights up momentarily.

Use the MASTER LEVEL control to adjust the overall volume.

7

If the LIMITER indicator flashes continuously, the internal power amplifier section is being

excessively overloaded and may malfunction.

Caution

Applying reverb or echo to the sound

Reverb recreates the warm ambience of an actual performance space, such as a concert hall or a
night club.

For each channel you want to apply reverb, set the corresponding REVERB

1

switch to ON ( ).

Use the REVERB control to adjust the overall reverb.

& MASTER LEVEL Control

Determines the volume of the signal output

from the SPEAKER jack. This allows you to

adjust the overall volume without changing

the relative volume balance among the

various channels (made with the LEVEL

controls) or the tone settings (made with the

Equalizer).

% CLICK switch

(for headphones/speaker)

Set this switch to ON to assign the

click (metronome) sounds that sent

to the channel 5/6 to the PHONES

jack, SPEAKER jack, and ST LINK

OUT R jack, but not to the ST SUB

OUT jacks.

Setting this switch to ON lets the

player monitor the click (metronome)

sounds of a sequencer or a

synthesizer.

# REVERB switch

Set this switch to ON to recreate the rich ambience

of various performance environments, such as a

concert hall or a night club. The switch lights up in

green when REVERB is ON ( ).

$ REVERB control

Determines the overall level of the reverb or echo

that is applied to the output signal. For best results,

this level should not be set very high, to avoid

possible feedback and to prevent the sound from

becoming “muddy” with too much reverb.
