  1. What devices are used for KTV sytem?
  • Karaoke Player – is a device that contains karaoke songs files in hard drive. You are able to toggle between vocal and non vocal, using remote control to select songs, app to search song, or connect to external monitor for Touch Monitor functions.
  • Amplifier – collects the music source from Karaoke Player and amplify it into louder, better quality sound to the speakers.
  • Mixer – transfer sound from microphone to Amplifier. You can also adjust sound effect such as echo, tremble with Mixer.
  • Mixing Amplifier = (Amplifier + Mixer) is specifically used for Karaoke, but you can also use this system for home theater purpose as well.
  • Speakers – is final destination of sound outcome.
  • Microphone – bring your voice (raw source) from the mic handheld to Amplifier or Mixer.
 

2. What is the difference of Amplifier, Mixer and Mixing Amplifier?

  • Amplifier = by definition, this device is to increase the amplitude of electrical signal in sound reproduction. It is similar to Receiver (Home theater device), but with bigger wattages (power). You need speakers to output the sound.
    • Noted that Amplifier has volume control for music, but no microphone ports.
  • Mixer = an electronic device to mix audio inputs that coming from different sources, such as Microphone.
    • Mixer is used to control your microphone outcome sounds. There are echo, delay, tremble, base, key control on the mixer for you to manually adjust according to your needs.
    • Mixer has microphone ports, microphone volume control, and effects control such as delay, base, etc.
  • Mixing Amplifier = Amplifier + Mixer.
    •  Mixing amplifier can deliver the depth and dynamic of your voice to the system, so you can have nearly full control of your outcome voice.  Indeed, basic amplifier can let you control echo, key, lower sound feedback for each individual microphone input. With mixing amplifier, you can control the volume of the music, and give the bass more power if you have a good pair of speakers.
    • Mixing Amplifier has both Music control volume, Mic control volume, Mic ports, all mixer effect knobs.
 

3. Can I set up KTV system without Amplifier and Speakers?

  • Yes, you can hook up a karaoke player directly to your TV with RCA cable (Red, White, and Yellow). However, the quality of sound outcome is very limited, and you will realize there is delay of microphone sound.
    • Red & White: for left and right audio output
    • Yellow: for image
  • Pros: save money
  • Cons: limited sound outcome, delayed microphone sound output

4. What is the role of Mixer, and why do I need it?

  • Mixer is used to control your microphone outcome sounds. There are echo, delay, tremble, base, key control on the mixer for you to manually adjust according to your needs. Mixer will mix your voice with your adjusted effect and deliver your sound outcome to Amplifier.
  • You will need a mixer if you have a receiver (or Amplifier without any microphone port).
  • If you have Mixing Amplifier, you don’t need a mixer.
 

5. Why there is no sound from my microphone when using HDMI output?

  • Noted that microphone uses Analog to transfer sound. Because AV Component/ RCA are Analog, so RCA is able to deliver your microphone sound.
  • HDMI is using digital to transfer sound, therefore, no microphone sound is delivered if you are using HDMI for audio output.

6. Can I use my home theater speakers for KTV setup?

  • Yes, but we do not suggest you to use your home theater speakers for KTV setup. These speakers are mainly made for watching movie and listening to music. They are not made for karaoke use, so they cannot handle loud noise from microphone.
  • Without professional handling and carefully use, your home theater speakers can be damaged when there is sudden high pitch voice, or loud noise.
 

7. Why do I need karaoke speaker?

  • We suggest to use Karaoke speakers instead of using home theater speakers (such as Bose, sound bar). Karaoke speakers or power amplifier speakers are made to handle higher power and more tolerate for loud sound input, or high pitched voice.
  • Investing a good pair of speakers not only bringing out excellent sound quality and better performance to your parties, they will save you money in a long run because these speakers are very durable and long-lasting if you take good care of them.

8. How many speakers do I need for KTV setup?

  • For KTV setup, we suggest to have 1 pair of speakers placing in the front, next to the TV and higher than your ears. You can hang or place the speakers on top of the shelves. If your speaker is floor stand version, simply place it on both sides of the TV.
  • This arrangement will deliver better sound quality for singing. Do not add additional speakers on the back of the room because this will create mic feedback when you sing.
 

9. How to choose compatible Amplifier and Speakers?

  • When choosing Amplifier and Speakers, the best way is looking for similar wattage output. This will deliver the best outcome from that set of Amplifier and Speaker. It is ok if wattages is 50-100 difference, but be caution when the wattage is more than 100w difference.
  • It is also ok to choose a bigger wattage Speakers than Amplifier.
    • wattage: Amplifier < Speakers –> OK
    • If your Speakers has larger wattages than Amplifier, it will not damage any of your device. But Amplifier doesn’t have enough power for Speaker to give the best sound outcome.
  • We do not suggest to pair Amplifier has larger wattages than Speakers.
    • wattage: Amplifier > Speakers –> handle with caution
    • If you accidently turn volume to max or there is loud voice from microphone, amplifier will push that power and your speakers may be blown up. You speakers will end up not working or sound really bad.
  • For example:
    • Amp (150w + 150w) pair with Speakers (150w + 150w) is the best combination
    • Amp (200w + 200w) pair with Speakers (250w + 250w) is ok
    • Amp (150w + 150w) pair with Speakers (300w + 300w) is still ok. But the speakers will not perform to its best result because Amplifier doesn’t have enough power to push it.
    • Amp (450w + 450w) pair with Speakers (250w + 250w). You need to handle with caution. A loud voice or loud background music can destroy your speakers.

10. Wired Microphone v.s Wireless Microphone

Wired MicWireless Mic
– only comes with Mic and Mic cable– comes with Mic handheld, Mic receiver, and Mic cables
– cheaper– expensive (depends on brands and categories)
– No frequency needed
– No power needed
– arranged of frequencies (for best signal to receive)
– required power source
– not convienience
– be caution with cable length
– you can walk any where within range
– no wired tripping
 

11. What is UHF and VHF Microphones?

  • UHF = Ultra High Frequency Microphone
    • UHF mics transmit between 450Mhz and 952Mhz (nearly 10 times wider range frequencies than VHF).
    • UHF wireless mic cost more than VHF mic.
    • You may consider to use UHF microphones: If you live in area with lots of TV broadcasting, or radio, there will be higher chance that your microphone’s frequencies will be interfered. Or if microphones are being used in events (not 1 location), for business. You don’t want to end up having bad signal or no signal for an event.
    • With UHF mic, you can switch to different frequency (within the range) if there is noise or no signal.
  • VHF = Very High Frequency Microphone
    • VHF mics transmit at around 170Mhz to 216Mhz.
    • VHF wireless mic is recommended for those live in fixed location and in area with less radio or TV broadcast channel, so it will less likely to compete with local signal.
    • It is also cheaper than UHF mic.
    • With stable signal, VHF Mic still deliver quality sound outcomes. Noted that some VHF Mic usually has fixed frequencies, so you cannot switch to other frequencies.
    • If you already have 1 set of VHF, before adding another set of VHF Mic, make sure the frequency is not repeating, or else it will compete for each other.
