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. 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. • 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. 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-1080, set IMPEDANCE SELECTOR on the rear panel before turning on the unit. Refer to “IMPEDANCE SELECTOR” on page 7. 2 En  PREPARATION NAMES OF PARTS AND THEIR FUNCTIONS Front panel PREPARATION The shaded part ( ) is provided for KMA-1080 only. 1 / (power on/off) Turn the power on/off. 9 MIC VOL (1/2/3**) Adjust the microphone input level.* 2 MUSIC BALANCE Adjust the volume balance.* 0 MIC Adjust the overall volume of all microphones. 3 MUSIC TONE (BASS/TREBLE) Adjust the low/high frequency response.* A Remote sensor This sensor receives signals from the remote control. 4 MIC ECHO DELAY Adjust the delay time between echoes.* B ECHO Adjust the amount of echo. 5 MIC ECHO REPEAT Adjust the amount of feedback.* C INPUT/Input source indicators (DVD/AUX**/ TAPE/BGM) INPUT is not available in the default setting.

Pull the lever up to open, then insert the conductor wire into the hole. (–) cord to (–) terminal (+) cord to (+) terminal [For KMA-1080] The shaded part ( OPERATION 2 ) is provided for KMA-1080 only. 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. 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. (Low) 15 mm (9/16”) Switch position 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. Low High Right speaker The shaded part ( Left speaker ) is provided for KMA-1080 only. (High) If your system uses: Speaker impedance level One speaker system 4 Ω or higher Two speaker systems 8 Ω or higher One speaker system 8 Ω or higher Two speaker systems 16 Ω or higher • 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. English 7 En  CONNECTIONS ■ Connecting to the balanced input 1.

Before using the remote control for the very first time, pull out the plastic tab, as shown. Plastic tab For information on replacing the battery, refer to next section. ■ Operation of remote control Within 6 m (20’) OPERATION 1 INPUT INPUT is not available in default setting. To activate INPUT, refer to “Input mode” on page 14. 1. Remote control The distance between the remote control and the remote sensor of this unit should be within 6 m (20’). Be sure to aim the remote control directly at the remote sensor on the front panel. 2 KEY CONTROL ( / / ) Transpose the key of the played music. 3 MIC ( / )* Adjust the overall volume of the microphones. 30° 30° 4 ECHO ( / )* Adjust the amount of echo. 5 MUSIC ( / )* Adjust the music volume. Continued to the next page. * The LED on the corresponding control on the front panel blinks during adjustment. 6 PRESET (1/2/3) Recall saved preset settings for MIC volume/ECHO amount/MUSIC volume/ECHO MODE. To save current settings of the above, press the desired button (PRESET 1, 2, 3 or KEY CONTROL on the front panel) for 3 seconds. Pressing KEY CONTROL saves settings to PRESET 1. When save is completed, “ ” on the KEY CONTROL blinks once. You can save up to 3 presets (PRESET 1/2/3) on this unit. Refer to “Power ON recall” on page 14. English 7 ECHO MODE Select NORMAL, WIDE or SPACIOUS (KMA-1080 only) echo. 11 En  REMOTE CONTROL 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. + side up 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. 12 En  GENERAL OPERATION OPERATION The shaded part ( ) is provided for KMA-1080 only. ■ Notes for the proper use of microphones 1 Connect the required number of microphones. 2 Set the power switches of this unit and 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. Adjust the microphone volume by rotating MIC. When different microphone volumes are not balanced, adjust MIC VOL using a flathead screwdriver. 5 Adjust the ECHO amount by rotating ECHO. 6 Adjust the key by rotating KEY CONTROL. 5 to 10 cm (2 to 3-15/16”) away from your mouth. Grasp the microphone below the head. English 4 • 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. 13 En  SETUP MODE ■ Menus in Setup mode You can set the following menus in Setup mode: 1.
