Professional karaoke machines, as the name suggests are for serious performers. It is not necessary that you purchase a pro system only if you own a pub or bar. Even home users with tenacity to sing day in and day out can enjoy thoroughly with professional systems. In short, these machines are the top of the line offerings that are unmatched in their power output, sound quality, and overall experience.
They usually come as component systems, something like stereo receivers and have to integrate with a home theater system. Many of these karaoke machines actually come with a huge database of tracks and can take on more through expansion slots, CDs or DVDs or even directly from the internet.
Professional units may or may not offer a high degree of connectivity. Those with a huge built-in database usually allow expansion slots only. A few even provide the ability to dock your iPod, use flash drives and more. Similarly, for output, you may get HDMI, Stereo, RCA and other outputs. Having all these connections does help especially if you wish to operate a commercial karaoke outlet.
Professional units come with pitch control, echo, equalizers and more. All of this is usually built into the machine and helps fine tune the singer’s tone to match with that of the song. Voice modulation is a must with professional units.
You don’t have to worry about quality of a pro unit, they are usually expensive for a reason and will offer a mesmerizing experience. What you do need to worry about is the power output. If you plan on using a professional system in a commercial backdrop, ensure that it has the right kind of amplifiers to power your professional speakers, the right playback features for the large screen LCD and so on.
