INTRODUCTION
Thank you for your purchase of the Yamaha KMA-1080/KMA-980 Digital Karaoke Mixing Amplifier.
This document is the owner’s manual for both KMA-1080 and KMA-980. Model names are given where the details of
functions are unique to each model. Illustrations for KMA-1080 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.
■ 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.
• 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.
■ 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-1080, set IMPEDANCE SELECTOR on the
rear panel before turning on the unit. Refer to
“IMPEDANCE SELECTOR” on page 7.

OPERATION
English
■ Connecting speaker cords
1 Pull the lever up to open, then insert the
conductor wire into the hole.
2 Close the lever to secure the conductor wire.
Before connection, strip a section of coating 15 mm
(9/16”) in length from the end of each cord using a
tool such as pliers.
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-1080................................................200 W + 200 W
KMA-980..................................................150 W + 150 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.
[For KMA-1080]
IMPEDANCE SELECTOR
• Before turning on this unit, be sure to set
IMPEDANCE SELECTOR on the rear panel to the
position whose requirements your speaker system
meets.
• Do not change IMPEDANCE SELECTOR setting
while the power to this unit is on, otherwise this unit
may be damaged.
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.

2. Loading a battery
The life of the battery used in the remote control is about
half a year under normal use. Remove the battery if the
remote control is not used for an extended period. When
the battery becomes weak, replace with a new CR2025
battery.
To replace the battery:
1. Using a small screwdriver, carefully slide out the
battery holder.
2. Remove the expired battery, and place the new
CR2025 battery onto the battery holder with the + side
facing up.
3. Slide the battery holder into the remote control, and
push it so that it clicks shut.
Improper use of batteries may cause a risk of battery
leakage and explosion.
Adhere to the following guidelines:
• Do not attempt to recharge the old battery.
• Insert a battery so that the positive (+) and negative (–)
poles are positioned as shown.
• Even if the shapes are the same, the voltage of batteries
may vary depending on the models. Be careful not to
use different model of battery.
• Dispose of the old battery in accordance with local
regulations.
