Instructions on how to adjust karaoke amplifier quickly and simply

Nowadays, karaoke systems are not only popular in service businesses, but also in many families. However, not everyone needs to master how to adjust karaoke amplifier standard. This is an important issue, for good sound quality, and the singer feels more enjoyable.

When to adjust the amplifier?

When the karaoke system is designed and installed, of course the technician will support the standard amplifier adjustment. But after a period of use, or during the singing process, the user still needs to adjust it. That is when:

– The voice is torn, broken, or distorted; the singer no longer recognizes his or her voice through the microphone.

– The singer feels very tired because he has to increase his strength when the microphone sound is weak.

– The sound is significantly reduced due to lack of high pitched vocals, low pitched vocals or music.

– Listeners feel tired due to unbalanced treble and bass.

– The singing voice is exposed due to too much resonance or the singer is tired, difficult to sing due to lack of resonance.

– The singer has no rhythm because the music and microphone sound do not blend together, making the singing sound disjointed.

How to adjust karaoke amplifier

Step 1: Leave the karaoke devices and amplifier in off state, connect the devices together and turn the volume to the lowest level before karaoke amplifier adjustment.

Step 2: Slowly adjust the total volume, microphone volume, and music volume knobs, stopping at the 12 o'clock position.

Step 3: Turn on the amplifier and test the karaoke microphone first. In this step, you need to pay attention to the area and soundproofing of the singing room, then turn the volume of Echo, Dly, Rpt to the right or left about 10 - 15 degrees and test, the voice is not too loud and does not repeat many times.

Note that for those who like bass, a lot of Bass, turn the LO knob of the microphone from 12 o'clock to 1 o'clock, for those with treble voices, turn HI similarly. But for those with weak voices, you need to turn the Mid volume of the Microphone from 10 o'clock to 1 o'clock to avoid tiring yourself out when singing. Do not increase the Mid and Hi to the maximum, because it will cause annoying screeching and howling.

Step 4: Adjust Echo, the reverberation of the singing voice

– Button number 16 RPT: Set at 12 o'clock position for 6 repetitions, should be set at this position for all voices and normal songs, if the singer has a good voice, can adjust to 5 repetitions, then turn the clock hands counterclockwise to 11 o'clock position.

– Button number 17 DLY is used to adjust the speed of the singing voice: normally this button is also set to 12 o'clock, when you need to increase the speed of the singing voice, turn this button to 12:30 or 13 o'clock and vice versa.

– Button number 14 LO: Used to increase or decrease the echo of the bass microphone sound.

– Button number 15 HI: Used to increase or decrease the echo of the high-pitched Mic sound.

Step 5: Adjust Music

– Adjust the 18 volume knob so that the music is as loud as the microphone or a little quieter than the microphone.

– Adjust the 21 treble knob to make it louder, when you hear the high notes breaking and tearing, turn it back, but don't adjust it too low to make the music sad and lifeless.

– Adjust the 19 bass knob to balance the treble, adjust and try to hear a strong bass that is not too rumbling.

– Adjust the 20 MID button (midrange adjustment button) of the music, set it to 9-10 o'clock position, do not adjust it too high, because the high midrange will override the microphone sound.

Step 6: Adjust Master (master knob set)

The total volume (Vol) should not be set too low, it should be kept at the 11-12 o'clock position. Adjusting the volume in music will help adjust the volume of the music and adjusting the mic to adjust the mic volume. With LO, MID, HI (bass, mid, high) should be set at around 11-1 o'clock.

Tips for adjusting mechanical and digital amplifiers

Tips for adjusting mechanical amplifiers

1. Learn about your amp: Before you tune it, learn about the features and how your amp works. Amps may have gates, EQs, filters, and other features. Understanding these will help you get the most out of your amp.
2. Frequency Equalization: Use your amplifier's EQ to balance the frequencies. Change the EQ settings to boost or cut different frequencies and check their effect on the sound.
3. Adjust the volume: Adjust the volume to suit your speakers and room. If the volume is too low, you won't be able to hear the sound clearly, while if the volume is too high, it will damage your hearing.
4. Test the sound before and after adjustment: Test the sound before and after adjustment to determine the best sound settings. You may need to make several adjustments to achieve the best sound.
5. Optimize speaker placement: The placement of the speakers also affects the sound. The speakers should be placed at the correct location and distance to optimize the sound.
6. Use high-quality signals: If you use high-quality audio signals, such as uncompressed music files or lossless audio formats, the audio will be played back in better quality.

2. Why does the microphone sound howl?

Want to edit anti-feedback digital echo effective, finding out the cause of the phenomenon of microphone howling also becomes very important. There are many different reasons explaining why karaoke microphones howl and hiss.

Firstly, due to the appearance of sound resonance. This is a common cause of howling microphones because the karaoke room reflects the sound emitted by the speakers, causing a resonance frequency phenomenon. This will cause the microphone to pick up a lot of noise, leading to unpleasant howling and hissing sounds.

Second, the microphone vent hole is blocked, which also causes the microphone to howl during karaoke use. When the microphone vent hole is blocked, the sound will often resonate inside the microphone body. This phenomenon will cause howling and hissing sounds to appear outside the speaker.

Third, holding the microphone incorrectly also often causes the microphone to make a whistling sound. Specifically, for wireless microphones, many users often have the habit of holding their hands to cover the antenna, as well as placing the microphone close to their mouth. These habits are the main causes of howling when the microphone is operating.

There are also many other reasons that lead to the phenomenon of howling sound in the microphone such as: lack of power in the microphone, lack of power in the amplifier, incorrect amplifier adjustment, etc. anti-feedback digital echo not correct, etc.
