• 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.

1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all instructions.
5 Do not use this apparatus near water.
6 Clean only with dry cloth.
7 Do not block any ventilation openings. Install in accordance

with the manufacturer’s instructions.

8 Do not install near any heat sources such as radiators, heat

registers, stoves, or other apparatus (including amplifiers) that
produce heat.

9 Do not defeat the safety purpose of the polarized or

grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10 Protect the power cord from being walked on or pinched

particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.

11 Only use attachments/accessories specified by the

manufacturer.

12 Use only with the cart, stand, tripod, bracket,

or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use
caution when moving the cart/apparatus
combination to avoid injury from tip-over.

13 Unplug this apparatus during lightning storms or when unused

for long periods of time.

14 Refer all servicing to qualified service personnel. Servicing is

required when the apparatus has been damaged in any way,
such as power cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally,
or has been dropped.

INTRODUCTION

Thank you for your purchase of the Yamaha KMA-700/KMA-500 Digital Karaoke Mixing Amplifier.
This document is the owner’s manual for both KMA-700 and KMA-500. Model names are given where the details of
functions are unique to each model. Illustrations for KMA-700 are mainly used for explanations.
Before using this unit, be sure to read this manual so that you can take full advantage of the features of this unit.
After you finish reading, keep this manual in a safe place in case you need it in the future. The manual should be very
helpful in understanding the Digital Karaoke Mixing Amplifier and solving any difficulties that may arise during use.

HANDLING PRECAUTIONS

■ Do not install the unit in the following
locations:

• In places exposed to direct sunlight or near heat

sources, such as a radiator.

• In places where heat cannot escape due to poor

ventilation, or are very humid or dusty.

• On a sloping surface or exposed to excessive vibration.

BEFORE CONNECTING

■ Connection precautions

• Be sure to switch off the power of the relevant

equipment before making any connection.

• The white input/output jacks of the amplifier are

designed for the left channel, while the red input/output
jacks are for the right channels. Be sure to connect the
cords without making a mistake in the color codes for
the left and right channels.

• Insert the plugs of the connection cords securely into

the jacks. If the connection is incomplete, there may be
no sound produced or noise may be generated.

• When unplugging the power cable from the AC wall

outlet, be sure to hold the plastic molding of the plug
itself and pull.

• For KMA-700, set IMPEDANCE SELECTOR on the

rear panel before turning on the unit. Refer to
“IMPEDANCE SELECTOR” on page 7.

• Except in the case of the U.S.A. model, VOLTAGE

SELECTOR on the rear panel of this unit must be set
for your local main voltage BEFORE plugging the
power cable into the AC wall outlet. Refer to
“VOLTAGE SELECTOR” on page 9.

• In places which may be exposed to rain, such as near a
window.

• In places which may be exposed to soot, vapor or heat,
such as near cooking facilities.

■ Power consumption of AC OUTLETS

(U.S.A. model only)

• Be careful that the total power consumption does not
exceed the wattage marked on the rear panel. Do not
connect appliances other than system components to
the AC OUTLETS of this unit.

• Do not connect a TV set to this unit; even if it indicates
a power consumption value below the permissible
value when the TV power is turned on.

Note

Be careful that the cord conductors projected from a terminal do
not contact with another cord. Contact from the conductors of
different speaker cords may cause damage to the system.

■ Important precautions for speaker
connection

• The maximum outputs of this unit are as follows:

KMA-700..................................................120 W + 120 W

KMA-500..................................................100 W + 100 W

Accordingly, the maximum input power of the speakers
used must exceed the above.

• Use Yamaha speakers to prevent any trouble or

damage caused by mismatching.

Connection examples

The minimum speaker impedance is 4 Ω. If two 6 Ω
speaker systems are connected in parallel, this will exceed
the design value and trigger a safety protector device.
When two speaker systems are used and the protector is
frequently activated, the speaker systems should be
connected serially instead.

other required components to ON.

3 Play the KARAOKE music source

component, and adjust the volume by
rotating MUSIC.

The music source is selected automatically in default
setting. To set the conditions for selection, refer to
“Auto input condition” on page 14. To select the
music source manually, refer to “Input mode” on
page 14.

4 Adjust the microphone volume by rotating

MIC.

When different microphone volumes are not
balanced, adjust MIC VOL using a flathead
screwdriver.

■ Notes for the proper use of microphones

• Sing into the microphone by holding it at a distance of 5 to
10 cm (2 to 3-15/16”) from your mouth.

• To ensure clear sound, grasp the microphone below the mic
head.

• Do not block the lower part of the windscreen. This will disturb
proper voice reproduction with unclear bass. Howling also
tends to occur in such cases.

电源插座中的电源线。

19 电池不能置于高热环境，比如火或直射日光等。
20 当环绕温度突然改变时会形成冷凝。从插座上断开电源

线，然后将本机单独搁置。

21 长时间使用本机时，本机会变热。关闭电源，然后搁置本

机使其冷却。

22 VOLTAGE SELECTOR （美国型号除外）

将电源插头插入交流电源插座之前，必须将本机后面板上
的 VOLTAGE SELECTOR 设定为本地电源电压。

前言

感谢您购买 Yamaha KMA-700/KMA-500 卡拉 OK 数码功放。
KMA-700 和 KMA-500 均适用本使用说明书。各机型独有功能的详细说明处注有型号名称。使用说明中主要使用
KMA-700 作为插图。
在使用本机之前，请务必通读本使用手册，以有效利用本机的所有功能。
阅读之后，请将本手册妥善保管，以备将来查阅。本手册对于理解卡拉 OK 数码功放和解决使用中出现的问题很
有帮助。

使用注意事项

■ 勿将本机设置在下列场所：

• 遭受直射阳光或附近有诸如取暖器之类的热源的地
方。

• 因通风差而不易散热的地方，或是非常潮湿、多尘
的场所。

• 斜面上或受到过多振动之处。

连接前的准备

■ 连接注意事项

• 在进行任何连接之前，确认各有关电器的电源都处
于关闭状态。

• 放大器上白色的输入 / 输出插孔用来连接左声道，
而红色的输入 / 输出插孔用来连接右声道。必须按

照左、右声道的色码正确连接导线。

• 将所要连接的导线的插头完全地插入插孔。如果连
接不牢固，可能没有声音或产生噪音。

• 当从交流电源插座上拔下电源线时，必须握住电源
线插头部分的塑造物拔取。

• 对于 KMA-700，请在打开电源之前设置后面板上的
IMPEDANCE SELECTOR。请参阅第 7 页 “IMPEDANCE

SELECTOR”。

• 除美国型号以外，在将电源线插入交流电源插座之
前，必须将本机后面板上的 VOLTAGE SELECTOR 设定

为适合本地区的电源电压。请参阅第 9 页“VOLTAGE
SELECTOR”。

• 靠近窗边等有雨水的地方。

• 靠近厨房等散发煤烟、蒸汽或热量的地方。
