Is a lock function an anti-theft device?
Most consumer karaoke equipment is designed with smaller gatherings in mind. A typical machine may have an audio output power rating of between 4 and 10 watts per channel, which can get surprisingly loud (maybe louder than you’d like, until you get used to letting it all hang out) but won’t carry a large room filled with party guests and conversation. If you want to break the ice at larger functions, look for a machine that includes auxiliary outputs that will permit connection to a more powerful audio system a larger stereo, for instance, or even a full-blown public address system.
