Frequently Asked Questions - DK7921N LG

How do I set up the DK7921N karaoke system?

Connect the system to your TV using the supplied audio/video cables. Plug in the power cord, insert a karaoke disc, and press PLAY. For microphone use, connect your mics to the front panel jacks.

How can I adjust the echo effect for my voice?

Use the ECHO control on the front panel or remote control. Increase the level for more reverb, decrease for a dry sound.

Can I play music from a USB flash drive?

Yes, insert a USB drive with MP3 or WMA files into the USB port. Use the remote to select USB mode and browse your files.

How do I connect the system to my TV?

Use the composite video (yellow) and audio (white/red) cables to the corresponding inputs on your TV. For better quality, use the component video output if available.

What should I do if the disc does not play smoothly?

Clean the disc with a soft cloth and ensure it is not scratched. Also check that the disc is placed correctly with the label facing up. If the issue persists, clean the lens with a suitable lens cleaner.

Is it possible to reduce the original singer's voice on a DVD?

Yes, press the VOCAL REDUCTION button on the remote. This works best with stereo tracks that have centered vocals.

How do I perform a factory reset?

Turn off the unit, then press and hold the STOP button on the front panel for 5 seconds until the display shows 'RESET'. Release the button, and the system will restore default settings.

Can I use any microphone with this system?

Most dynamic microphones with a 6.3mm jack will work. Ensure the mic has an impedance between 200 and 600 ohms for optimal performance.

How should I clean and maintain the unit?

Unplug the unit before cleaning. Wipe the outer surface with a soft, dry cloth. For the disc tray and lens, use compressed air or a recommended lens cleaner. Avoid using solvents or water.

What are the spare parts available for the DK7921N?
