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
• 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
• Do not open the instrument or attempt to
disassemble the internal parts or modify them
in any way. The instrument contains no userserviceable parts. If it should appear to be
malfunctioning, discontinue use immediately
and have it inspected by qualified Yamaha
service personnel.

• Unplug the AC power adaptor when not using
the instrument, or during electrical storms.

Water warning
• 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.

• 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.

• Never insert or remove an electric plug with wet
hands.

Location
• 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.

Fire warning
• Do not put burning items, such as candles, on
the unit.
A burning item may fall over and cause a fire.

If you notice any abnormality

• 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.

• 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.

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

Maintenance
• When cleaning the instrument, use a soft, dry
cloth. Do not use paint thinners, solvents,
cleaning fluids, or chemical-impregnated
wiping cloths.

Handling caution
• 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.

• 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.

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:

Connections
• 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.

Power supply/AC power adaptor
• When removing the electric plug from the
instrument or an outlet, always hold the plug
itself and not the cord.
(3)-9

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.

Operating Instructions
Turning On the
MLC-100 System
To protect the external speaker system
from possible damage (and to avoid an
annoying “pop” in any connected headphones), always set the volume controls
of all equipment to 0 or minimum and turn
on the power of the system components
in the following order:
1) the MLC-100 console
2) all connected instruments
3) any connected source (CD player,
cassette deck, etc.)
4) the external speaker system
CAUTION: Even when the instrument is turned off, electricity is still
flowing to the instrument at the minimum level. When you are not using the
MLC-100 for a long time, make sure
you unplug the AC power adaptor from
the wall AC outlet.

Setting the Levels
Before conducting a class with the MLC100, always make sure the three level
controls – INPUT, OUTPUT and
T.PHONES – are set to the proper levels.
Have the students listen on their headphones while you listen on yours, play
your instrument and/or any other audio
source you will be using, talk into your
microphone, and make sure that you and
all students can hear everything properly.
Also, be sure to first set the T.PHONES
control to a position around 2 or 3 o’clock
before adjusting other levels (such as
that of a compact disc player or the
teacher’s instrument). When the control is
set to this position, the teacher will hear
the sources at roughly the same level as
what the students hear, making it easy to
set the proper levels of those sources.

Setting Up the Console – Enabling
specific Student Stations
Before conducting a class, set the MLC100 for the number of students in the
class. This is important when using the
Automatic Scan function, If fewer than
sixteen students are in the class yet all
student stations are enabled on the MLC100, the Automatic Scan function would
needlessly select empty student stations
for monitoring. Enabling specific stations
here lets you avoid Automatic Scanning
of empty student stations. (When the
MLC-100 is turned on, all sixteen stations
are automatically enabled.)
To enable specific student stations:

Press and hold down the
[INSTRUCT] SELECT button for approximately three seconds. (All enabled Individual Student selectors light.)

While holding down the
[INSTRUCT] SELECT button, press those
Individual Student selectors that correspond to the unused student stations. For
example, if student stations 11 and 15 are
empty, press Individual Student selectors
11 and 15.

It is best to have students fill up the lower
numbered stations, if fewer than sixteen
students are present. This not only facilitates pair work, but it also lets you use the
following alternate method of enabling
specific empty student stations:
While holding down the [INSTRUCT]
SELECT button, press the STUDENT
GROUP COMMUNICATION SELECTORS in the D row corresponding to the
last occupied student station. All buttons
from station 1 to the station selected light.
Note: In either of the above methods,
you can hold down the [INSTRUCT]
SELECT button and immediately use
the Individual Student selectors or D
row of STUDENT GROUP COMMUNICATION SELECTORS. All enabled
Individual Student selectors light. Set
them in the same way as described in
step #2 above.

MLC-100.book Page 7 Monday, October 17, 2005 7:03 PM

Assigning Students
to Groups

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 button again.

Note: When using Pair mode, make
sure that the students fill up adjacent
numbered stations as much as possible, to ensure that each student has a
partner.

Note: If you wish to make nonstandard pair assignments (such as student 2 with student 10), use the group
functions to assign the two students to
a group.

To have students play together in groups:
Press the [GROUP] GROUP button. (The
button lights.)

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 student 10 to group C, press the third STUDENT GROUP COMMUNICATION
SELECTORS from the top in the row
labeled “10.”

Selecting the
Teacher’s Monitor –
Teacher’s Instrument
or Input
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 students, or to run through a part before performing 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.)

This sets up the system so that the members 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, students cannot be assigned to any other
group.
To turn off this mode and return to the previous Group assignment, press the
[GROUP] GROUP button again.

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.
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 cancelled and the default setting – that of
individual or solo instruction – is
recalled.

The selected sound source is now output
to the teacher’s headphones. Press the
appropriate button again to turn off monitoring of the source. The teacher’s instrument monitor is automatically set to on as
a default when the unit is turned on.

(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
on the master also affect the slave instrument as well. Other controls and functions must be executed from each unit.

* Specifications and descriptions in this owner’s manual are
for information purposes only. Yamaha Corp. reserves the
right to change or modify products or specifications at any
time without prior notice. Since specifications, equipment
or options may not be the same in every locale, please
check with your Yamaha dealer.

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 instrument 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 system, 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 instrument.
• 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 instrument (vinyl can stick to and discolor the surface).
■ 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.
