Karaoke amplifiers are a distinct category — different from standard home stereo amplifiers in ways that matter a lot if you're buying for home entertainment, venue use, or wholesale distribution.
1. Microphone Inputs and Mixing
Number of mic inputs: 2 is standard; 4 is better for group karaoke
XLR vs. 6.35mm: XLR is higher quality; 6.35mm is more common on consumer units
Independent mic volume control: Each mic should have its own level knob
Mic priority / ducking: Automatically lowers music when someone speaks
2. Echo and Reverb Control
Echo depth/delay knob — Controls how long the echo sustains
Echo repeat — Number of echo repeats
Built-in reverb presets — Hall, room, studio settings are a bonus
For venue use (KTV rooms, bars), prioritize units with flexible echo control. Home users are usually satisfied with basic echo + reverb.
3. Power Output for the Room Size
Small room / home use: 100W RMS per channel
Medium room / small venue: 200W RMS per channel
Large KTV room / commercial: 300W+ RMS per channel
4. Tone Controls and EQ
Bass / Mid / Treble — Standard 3-band EQ
Vocal enhancement — Boosts presence frequencies (2kHz–5kHz) for clarity
Key control (pitch shift) — Lets singers match songs to their vocal range without changing tempo
5. Connectivity for Modern Use
Bluetooth input — For wireless streaming
USB / SD card playback — For offline song libraries
HDMI or AV output — To display lyrics on TV
Optical input — For connecting to TV audio
