[. . . ] THIS CLASS B DIGITAL APPARATUS MEETS ALL REQUIREMENTS OF THE CANADIAN INTERFERENCE-CAUSING EQUIPMENT REGULATIONS. 3 FEATURES ÷ Three audio inputs (VCD/LD, TAPE and AUX), two video inputs (VCD/LD and AUX) and two video outputs (MONITOR OUT 1 and 2) allow you to connect various audio/video components. ÷ Combination of three different Echo controls (VOLUME, REPEAT, DELAY) gives various echo effects to voices through the microphones. ÷ Digital Key Control function allows you to select the desired musical pitch. (±2 note, 9 steps) ÷ 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?*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 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. Connecting the AC OUTLETs 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.
