- Unpacking and Placement: Carefully remove the amplifier from its packaging. Place it on a flat, stable surface with adequate ventilation around all sides.
- Voltage Selection: Before connecting the power cord, ensure the VOLTAGE SELECT switch on the rear panel is set to match your local power supply (110V or 220V). Incorrect voltage selection can damage the unit.
- Speaker Connection: Connect your speakers to the SPEAKER SYSTEM terminals on the rear panel. Ensure correct polarity (+ to + and - to -). The amplifier supports 8 Ohm speakers.
- Audio Source Connection: Connect your audio sources (e.g., DVD player, karaoke machine, computer) to the desired RCA INPUTs (DVD, VCR, AUX, MUSIC INPUT) on the rear panel using appropriate RCA cables.
- Microphone Connection: Plug your microphones into the 1/4" MIC 1, MIC 2, or MIC 3 inputs on the front panel.
- Power Connection: Once all connections are secure, plug the power cord into the AC INPUT on the rear panel and then into a wall outlet.
Operating Instructions
- Power On: Press the POWER button on the front panel. The power indicator light will illuminate.
- Select Input Source: Use the INPUT selector buttons (DVD, VCR, AUX) on the front panel or remote control to choose your desired music source.
- Adjust Music Volume: Slowly turn the MUSIC MASTER VOL knob clockwise to increase the music volume to a comfortable listening level. Use the individual MUSIC tone controls (LO, MID, HI) to adjust bass, midrange, and treble.
- Adjust Microphone Volume: Ensure the individual VOL knobs for each connected microphone are at a low setting. Speak into the microphone and slowly increase the MIC MASTER VOL and the individual microphone VOL knobs until your voice is audible and balanced with the music.
- Apply Echo and Tone: Use the individual ECHO knob for each microphone to add reverberation. Adjust the individual LO, MID, HI knobs for each microphone to fine-tune your vocal tone. The main ECHO section controls the overall echo characteristics.
- Key Control: For karaoke, use the 16 BIT DIGITAL KEY CONTROL buttons (# for sharp, b for flat) on the front panel or remote to adjust the musical key of the song to suit your vocal range.
- Multiplex Functions: If using multiplex karaoke media, the AUT/S (Auto Singing-mate) and V.C. (Vocal Cancellation) buttons on the front panel or remote can be used to activate these features.
