MS202 II

Thank you for purchasing a Yamaha MS202 II Monitor Speaker. The
MS202 II employs a 4 inch full-range speaker in a compact bass-reflex style
cabinet. Its faithful sound reproduction capabilities make it ideal for home
recording and personal practice. Since a magnetic field-cancelling speaker
is used, the MS202 II can be placed next to a television or video monitor
without causing interference, making it the perfect choice for Audio/Video
system applications.

Explanation of Graphical Symbols

The lightning flash with arrowhead symbol, within an
equilateral triangle is intended to alert you to the presence of
uninsulated “dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to constitute a
risk of electric shock to persons.

The exclamation point within an equilateral triangle is
intended to alert you to the presence of important operating
and maintenance (servicing) instructions in the literature
accompanying the appliance.

supply only of the type described in the operating instructions or as
marked on the appliance.

11. Grounding or Polarization — The precautions that should be taken
so that the grounding or polarization means of an appliance is not
defeated.

12. Power-Cord Protection — Power-supply cords should be routed so
that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the
appliance.

the vicinity of overhead power lines or other electric light or power
circuits, or where it can fall into such power lines or circuits. When
installing an outside antenna system, extreme care should be taken
to keep from touching such power lines or circuits as contact with
them might be fatal.

20. Overloading — Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in a risk of fire or
electric shock.

21. Replacement Parts — When replacement parts are required, be
sure the service technician has used replacement parts specified by
the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric shock, or

three pin plug.

Precautions

■

Warnings

1. Connect this unit’s power cord only to an AC outlet of the
type stated in this Owner’s Manual or as marked on the
unit. Failure to do so is a fire and electrical shock hazard.

2. Do not allow water to enter this unit or allow the unit to
become wet. Fire or electrical shock may result.

3. Do not place heavy objects, including this unit, on top of
the power cord. A damaged power cord is a fire and electri­cal shock hazard. In particular, be careful not to place
heavy objects on a power cord covered by a carpet.

4. Do not place a container with liquid or small metal objects
on top of this unit. Liquid or metal objects inside this unit
are a fire and electrical shock hazard.

5. Do not remove the unit’s cover. You could receive an elec­trical shock. If you think internal inspection, maintenance,
or repair is necessary, contact your dealer.

6. Do not modify the unit. Doing so is a fire and electrical
shock hazard.

7. If lightning begins to occur, turn off the power switch of the
unit as soon as possible, and unplug the power cable plug
from the electrical outlet.
If there is a possibility of lightning, do not touch the power
cable plug if it is still connected. Doing so may be an elec­trical shock hazard.

8. If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the unit
with a damaged power cord is a fire and electrical shock
hazard.

9. If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the unit,
turn it off immediately. Remo ve the power cord from the A C
outlet. Consult your dealer for repair. Using the unit in this
condition is a fire and electrical shock hazard.

10.Should this unit be dropped or the cabinet be damaged,
turn the power switch off, remove the power plug from the
AC outlet, and contact your dealer. If you continue using
the unit without heeding this instruction, fire or electrical
shock may result.

■

Cautions

1. Keep this unit away from the following locations:
Locations exposed to oil splashes or steam, such as near
cooking stoves, humidifiers, etc.
Unstable surfaces, such as a wobbly table or slope.
Locations exposed to e xcessive heat, such as inside a car
with all the windows closed, or places that receive direct
sunlight.
Locations subject to excessiv e humidity or dust accum ula­tion.

2. Do not place the power cord close to a heater. It may melt,

causing fire or electrical shock.

3. Hold the power cord plug when disconnecting it from an AC

outlet. Never pull the cord. A damaged power cord is a
potential fire and electrical shock hazard.
Do not touch the power plug with wet hands. Doing so is a
potential electrical shock hazard.

4. Use extreme caution when using a speaker stand and

speaker bracket.

5. To relocate the unit, turn the power switch off, remove the

power plug from the AC outlet, and remove all connecting
cables. Damaged cables may cause fi re or electrical shock.

6. Turn off all musical instruments, audio equipment, and

speakers when connecting to this unit. Use the correct con­necting cables and connect as specified.
Always low er the volume control to minimum before turning
on the power to this unit. A sudden blast of sound may
damage your hearing.

7. Do not output distorted sounds for long periods of time, as this

will cause the speaker to heat up , leading to a fire hazard.

8. If you know you will not use this unit for a long period of

time, such as when going on vacation, remove the power
plug from the AC outlet. Leaving it connected is a potential
fire hazard.

9. To prevent electrical shock when cleaning the unit, remove

the power plug from the AC outlet.

10.To allow for the efficient release of heat, maintain a gap of
10 cm or more between the rear of the MS202

II

and the
wall in addition to a gap of 20 cm or more between the top
of the MS202

II

and the ceiling. Locate the MS202

II

away
from other equipment. If the release of heat is insufficient,
the heat will remain inside the device, and result in a fire.

Example Set up

After switching the power off for all components in your system, connect the MS202 II ’s power cable to an AC outlet. There are any
number of ways to use the MS202 II , and exact connections will depend on your system and needs. Here is one example set-up.

A pair of MS202 II can be used as amplification for a stereo monitor system. You can sing and play along with the music on mics and
instruments plugged into the front panel LINE INPUTs. In addition, you can use a pair of MS202 II s for recording if you plug elec­tronic keyboards, rhythm boxes, etc, directly into the LINE INPUTs, and connect the LINE OUT jacks to the inputs of a cassette
recorder.

In this example, the monitor outputs of a Yamaha MD recorder Multitrack are connected to the LINE 2 inputs on a pair of MS202 II s
for multitrack monitoring.
