(±2 note, 9 steps) ACCESSORY After unpacking, check that the following accessories are supplied. Remote control transmitter KARAOKE VCD/LD TAPE AUX MPX/ STEREO ONE TOUCH KARAOKE VOCAL AID KARAOKE DSS I BALLAD POPS JAZZ ROCK È – i + VOLUME ÷ With Sound Multiplex sources, the volume of the original vocals and the music can be adjusted by using the MPX BALANCE control. ÷ MUSIC VOL control lets you balance your vocals and the music by adjusting the music volume level. ÷ VOCAL AID replaces the original vocals with your voice when you sing. ÷ The built in KARAOKE DSS sound field processor has four different settings (BALLAD, POPS, JAZZ, and ROCK) to let you obtain the desired atmosphere according to the music type. ÷ ONE TOUCH KARAOKE lets you cut the original vocals from general stereo sources so they can be used as karaoke sources. ÷ Your karaoke play can be recorded with a cassette deck connected to this unit. ÷ High-power built-in amplifier What are the Sound multiplex sources? With a Sound Multiplex tape designed for karaoke use or a sound multiplex disc (laser karaoke disc, etc.), generally, the right channel contains both background music and original vocals, and the left channel contains only background music. Thus, these sources allow you to select only the background music, or to adjust the volume between original vocals and music by rotating the MPX BALANCE control. Note: There are also other types of karaoke sources, with which the sound adjustments of this unit may not function properly. Please confirm the type is the karaoke source you have purchased, before reproducing it with this unit. 4 Batteries (size AA, R6, UM-3)  CONNECTIONS ÷ Be sure to disconnect power cords of all the audio and video components from the AC outlets. Do not turn the power on until all connections are completed. ÷ When making connections between this unit and other components, make sure that all connections are correct, L (left) to L, R (right) to R.

For powerful sound To reproduce a more powerful sound, connect a power amplifier (instead of a subwoofer) to the PRE OUT jacks to drive high-power speakers. *1 GND terminal Usually, it is not necessary to make a connection to this terminal. However, when excessive noise exists, connect the GND terminals of this unit and other components to minimize the noise. 5  Connecting speakers Connecting the AC OUTLETs Connect the SPEAKERS terminals to your speakers with wire of the proper gauge cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity (+ and – markings) of the speaker wires are correct. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers. ÷ Use speakers with an impedance of 6 ohms or more. Using speakers with an impedance of less than 6 ohms may result in malfunction or damage to this amplifier. ÷ Do not connect more than one pair in parallel to this amplifier. This unit is equipped with two UNSWITCHED AC OUTLETs for connecting the power cords of other components to this unit. The power to these outlets is not controlled with this unit’s POWER switch. They will continuously supply power to any component connected to them. The total maximum power consumption of components connected to these outlets must not exceed 100 watts. 1 2 3 Press down the tab. Insert the bare wire. [Remove approx. 5mm insulation from the speaker wires.] Raise the tab to secure the wire.
