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:
•Only use the voltage specified as correct for the
instrument. The required voltage is printed on
the name plate of the instrument.
• Use the specified adaptor (PA-6 or an
equivalent recommended by Yamaha) only.
Using the wrong adaptor can result in damage
to the instrument or overheating.
•Check the electric plug periodically and remove
any dirt or dust which may have accumulated
on it.
• Do not place the AC adaptor 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.
• Do not open the instrument or attempt to
disassemble the internal parts or modify them
in any way. The instrument contains no user-
serviceable parts. If it should appear to be
malfunctioning, discontinue use immediately
and have it inspected by qualified Yamaha
service personnel.
• Do not expose the instrument to rain, use it
near water or in damp or wet conditions, or
place containers on it containing liquids which
might spill into any openings.
•Never insert or remove an electric plug with wet
hands.
• Do not put burning items, such as candles, on
the unit.
A burning item may fall over and cause a fire.
• If the AC adaptor cord or plug becomes frayed
or damaged, or if there is a sudden loss of
sound during use of the instrument, or if any
unusual smells or smoke should appear to be
caused by it, immediately turn off the power
switch, disconnect the adaptor plug from the
outlet, and have the instrument 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
instrument or other property.
These precautions include, but are
not limited to, the following:
• When removing the electric plug from the
instrument or an outlet, always hold the plug
itself and not the cord.
• Unplug the AC power adaptor when not using
the instrument, or during electrical storms.
• Do not connect the instrument to an electrical
outlet using a multiple-connector. Doing so can
result in lower sound quality, or possibly cause
overheating in the outlet.
•Do not expose the instrument 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 use the instrument in the vicinity of a
TV, radio, stereo equipment, mobile phone, or
other electric devices. Otherwise, the
instrument, TV, or radio may generate noise.
• Do not place the instrument in an unstable
position where it might accidentally fall over.
• Before moving the instrument, remove all
connected adaptor and other cables.
•When setting up the instrument, 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.
• Before connecting the instrument to other
electronic components, turn off the power for
all components. Before turning the power on or
off for all components, set all volume levels to
minimum. Also, be sure to set the volumes of
all components at their minimum levels and
gradually raise the volume controls while
playing the instrument to set the desired
listening level.
• When cleaning the instrument, use a soft, dry
cloth. Do not use paint thinners, solvents,
cleaning fluids, or chemical-impregnated
wiping cloths.
•Do not place vinyl, plastic or rubber objects on
the instrument, since this might discolor the
panel or keyboard.
• Do not rest your weight on, or place heavy
objects on the instrument, and do not use
excessive force on the buttons, switches or
connectors.
•Do not operate the instrument 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.
Yamaha cannot be held responsible for
damage caused by improper use or
modifications to the instrument, or data
that is lost or destroyed.
Always turn the power off when the instrument is
not in use.
Even when the power switch is in the “STANDBY”
position, electricity is still flowing to the
instrument at the minimum level. When you are
not using the instrument for a long time, make
sure you unplug the AC power adaptor from the
wall AC outlet.

Pair and Group Play
To have students play together in pairs:
Press the [GROUP] PAIR button. (The
button lights.)
This automatically pairs all of the students
– student 1 with student 2, student 3 with
student 4, and so on, up to student 15
with student 16. The paired students can
hear each other’s performances and
communicate with each other.
To turn off pair mode, press the PAIR but-
ton again.
To have students play together in groups:
Press the [GROUP] GROUP button. (The
button lights.)
This sets up the system so that the mem-
bers of the currently assigned groups can
hear each other’s performances and
communicate with each other.
(For information on assigning students to
groups, refer to “Assigning Students to
Groups”.)
To turn off group mode, press the GROUP
switch again.
To have all students play together:
Assigning all active students to one
group (group A) can be done in a single
keystroke. To do this, simultaneously
press [GROUP] GROUP and PAIR. (The
GROUP button and all student buttons in
the A row will light.) In this condition, stu-
dents cannot be assigned to any other
group.
To turn off this mode and return to the pre-
vious Group assignment, press the
[GROUP] GROUP button again.
Assigning Students
to Groups
To assign a student to a particular group:
In the appropriate column of STUDENT
GROUP COMMUNICATION SELECTORS,
press the one corresponding to the group
(A, B, C, D) to which you wish to assign
the student. For example, to assign stu-
dent 10 to group C, press the third STU-
DENT GROUP COMMUNICATION
SELECTORS from the top in the row
labeled “10.”
Up to four groups can be made with any
combination of students.
To re-assign a student from one group
to another:
Press the desired group button for the
student.
These Monitor controls let only the
teacher listen to the sources. This would
come in handy, for example, when the
teacher needs to check a CD music
selection before playing it for the stu-
dents, or to run through a part before per-
forming it for the class.
To select the teacher’s instrument or
INPUT signal for teacher monitoring:
Press the appropriate button, [MONITOR]
T.INST (for teacher’s instrument) or
[MONITOR] INPUT (for the INPUT signal),
or both. (The selected button lights.)
The selected sound source is now output
to the teacher’s headphones. Press the
appropriate button again to turn off moni-
toring of the source. The teacher’s instru-
ment monitor is automatically set to on as
a default when the unit is turned on.
Note:
When using Pair mode, make
sure that the students fill up adjacent
numbered stations as much as possi-
ble, to ensure that each student has a
partner.
Note:
If you wish to make nonstan-
dard pair assignments (such as stu-
dent 2 with student 10), use the group
functions to assign the two students to
a group.
Note:
Group settings are memorized
only for as long as the power is on.
When the power is turned off and back
on again, all group settings are can-
celled and the default setting – that of
individual or solo instruction – is
recalled.

Using Two MLC-100s
Two MLC-100s can be connected
together in daisy-chain fashion, for
classes exceeding 16 students. Teacher
monitoring, as well as input of the
teacher’s instrument and INPUT signal,
can be done from the master MLC-100
(the first unit in the chain; see connection
illustration below). Though the groups on
each unit are separate (for example, the
A group on one units is separate from the
A group on another), the slave unit can
be monitored from the master. Be sure to
use only NB-100A, NB-100B or NB-100C
cables. The [INSTRUCT] ALL, [DEMO]
OUTPUT and [DEMO] PHONES buttons

Note: If there is a humming noise in the system, check the cables and
connections. First make sure that all connections are secure and unwind
any cables that have been coiled. If the cable is too long and needs to be
gathered, bundle and tie it. (Do not wind it in a coil.)
MAINTENANCE
■ Location
Do not expose the instrument to the following
conditions to avoid deformation, discoloration, or
more serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
■ Power Supply
• Use the supplied AC Power Adaptor only. The
use of other adaptors may result in irreparable
damage to both the adaptor and the MLC-100.
•Turn the power switch OFF when the instru-
ment is not in use.
•The power adaptor should be unplugged from
the AC outlet if the instrument is not to be used
for an extended period of time.
• Unplug the power adaptor during electric
storms.
•Avoid plugging the power adaptor into the
same AC outlet as appliances with high power
consumption.
■ Turn Power OFF When Making Connections
•To avoid damage to the instrument and other
devices to which it is connected (a sound sys-
tem, for example), turn the power switches of
all related devices OFF prior to connecting or
disconnecting cables.
■ Handling and Transport
• Never apply excessive force to the controls,
connectors or other parts of the instrument.
• Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
•Disconnect all cables before moving the instru-
ment.
•Physical shocks caused by dropping, bumping,
or placing heavy objects on the instrument can
result in scratches and more serious damage.
■ Cleaning
• Clean the cabinet and panel with a dry soft
cloth.
•A slightly damp cloth may be used to remove
stubborn grime and dirt.
• Never use cleaners such as alcohol or thinner.
•Avoid placing vinyl objects on top of the instru-
ment (vinyl can stick to and discolor the sur-
face).
■ Electrical Interference
• This instrument contains digital circuitry and
may cause interference if placed too close to
radio or television receivers. If this occurs,
move the instrument further away from the
affected equipment.
■ Service and Modification
• The MLC-100 contains no user serviceable
parts. Opening it or tampering with it in anyway
can lead to irreparable damage and possibly
electric shock. Refer all servicing to qualified
YAMAHA personnel.
YAMAHA is not responsible for damage caused by
improper handling or operation.
