Home Karaoke: Essential Technical Terms You Should Know

All-In-One Karaoke Systems

All-in-one karaoke systems are the most popular type of home karaoke machines available. These systems integrate all essential components, including the amplifier, mixer, player, and speakers, into a single unit. To get started, simply connect the machine to a TV and a power supply, plug in your microphone, and you're ready to sing. Some all-in-one systems even feature a built-in display monitor for lyrics, eliminating the need for a TV.

Key Features:

• Integrated Components: Amplifier, mixer, player, and speakers.
• Easy Setup: Connect to a TV and power supply, then plug in the microphone.
• Built-in Display: Some models include a monitor for lyrics.

CDG or CD+Graphics

CDG, or CD+Graphics, is the most common karaoke media type. These discs are the same size as standard CDs but include graphics or lyrics that appear on a TV screen when played on a CD+G player connected to a monitor. While CDGs are compatible with standard audio players, the graphics will not be displayed.

Key Features:

• Media Type: Same size as standard CDs.
• Graphics Display: Lyrics appear on the TV screen.
• Compatibility: Works with standard audio players (without graphics).

Auto Voice Control (AVC) or Automatic Vocal Cancel

Auto Voice Control (AVC) is a feature that mutes the lead vocals on a multiplex disc when a singer starts singing into the microphone. When the singer stops, the lead vocals return. This feature is particularly useful for learning new songs and is commonly found on most home karaoke machines.

• Lead Vocal Control: Mutes lead vocals when singing.

Multiplex CDGs

Multiplex CDGs are special CDs that include lead vocals, which can be removed. These discs are recorded in a way that allows the vocals to be separated from the music. Typically, each disc contains about eight songs, with each song appearing twice—once with lead vocals and once without. The tracks are usually clearly labeled.

Key Features:

• Lead Vocal Removal: Vocals can be separated from the music.
• Track Duplication: Each song appears twice (with and without vocals).
