What's Included

  • FIFINE K040 receiver (NO built-in amplifier, external speaker is NECESSARY! 
  • 2 antennas
  • 2 wireless handheld microphones 
  • 2 foam caps
  • 2 anti-rolling rings
  • Power adapter 
  • 1/4" to 1/4" audio cables 


Derives from long-standing K036 wireless system, but outshines it

  • Combing ruggedness & reliability, clarity and multiple-channel in an easy to use system. Compact receiver is pre-paired with 2 handheld mics.  
  • Independent controls do not sound close to fancy feature? How about the party piece - level meter, providing a visual way to stay off distortion.   
  • Putting the unit with two antennas on a rack mount or limited space is going to be a problem? Not at all. You can angled the detachable & fully adjustable antennas at any position to fit in.
  • Balanced XLR jacks output channel A and channel B separately for upper-level connection. While 1/4" out makes the whole unit serve as a small mixer for quick karaoke night setup.  

Absolute workhorse, please show no mercy to it 

  • Plug and play device, do not have to make any change whatsoever. Hook the system up and turn the mics on, it is just going to work amazingly.  
  • Survives the rigorous drop & beat test; comes with 2-year warranty to assure you of the best durability.    
  • If you are a MC or DJ who often passes microphone to people between tables for their speech, an expensive Shure could be overkill while K040 could just do this job well.   

It is never enough to emphasize the importance of frequency

  • People usually do not take frequency restriction seriously. But the reality is that if a system got just a few channels, once they experience interference, your show is going to be ruined.
  • What is nice about K040 wireless is the 50 frequency channels for each mic. If you are a DJ who travels a lot to different cities (therefore different wireless limitation), it is the gear that can offer you peace in mind!
  • Up to 116 feet of ultra high frequency transmission allows outdoor use without worries of dropout or cutout.  
  • What's more, UHF (Ultra High Frequency) is a more penetrable and powerful signal, therefore a better choice for using in built-up areas. 

Do not make sound quality the showstopper 

  • Audio is important on presentation, live performance so it is for small gigs or just a Saturday karaoke night at home.    
  • Sound quality of K040 may not work all the way up to a concert, but because of flat and wide frequency response, it does make the projected audio sounds more like you than any other budget system can do.
  • The highs-favor calibration helps for a bit of clarity for those who have low voice like a broadcast host or a DJ.
  • Thanks to a customized capsule, it is going to pick up a lot more sound from the source, being more user-friendly to those inexperience in talking into a mic. Because they may not always keep in mind pointing a mic directly to their mouth to get the full sound.
