Common Amplifier Issues: Troubleshooting Guide

When using any electronic device, there are inevitably times when various issues arise, and amplifiers are no exception. During the use of amplifiers, certain errors or malfunctions may occur due to various reasons. Therefore, we must identify the causes in order to provide effective and appropriate solutions.

Uneven Sound in Amplifiers

Amplifiers producing uneven or imbalanced sound, particularly when only one side is affected, is a common occurrence. This phenomenon results in the amplifier's sound output from the speakers being uneven, with one side louder than the other.

Amplifier Produces Popping Noise When Powering On or Off

Amplifiers emitting popping noises, particularly when turning them on or off, is a common occurrence with various causes, such as: Faulty amplifier power source; Malfunctioning music player causing sound distortion; Amplifier internal malfunction affecting sound quality.

Amplifier Experiencing Echo Burnout

Echo burnout in amplifiers refers to the loss of echo control capability. The cause of this issue includes:

• The first issue arises from excessively adjusting the buttons in the echo area, causing the buttons to deviate from their previous position.
• The second issue may stem from IC burning because your amplifier is out of warranty. 

How to adjust Bass – Mid – Treble sound in amplifier

After understanding and knowing some common issues when using amplifiers, we also need to know how to adjust bass, mid, and treble sound standards in our own amplifiers. Let's go through some methods below with Mytour Blog!

Adjusting bass sound in amplifier

To adjust the bass sound, gently tap the microphone head or try blowing strongly into the microphone head. Next, you will feel the sound coming from the microphone is deep and solid enough or not. If not, turn the LOW knob on the amplifier to adjust the bass sound.

One tip to note: People with thin high voices should increase the bass to ensure the sound from the microphone is not harsh and clear. In case you have a deep voice tone, you should lower the bass sound to create a balance between the amplifier and your voice. 

Adjusting mid sound in amplifier

Adjusting mid sound is similar to adjusting bass sound. When trying, speak into the microphone with the word “HI” to ensure the sound is clear. For mid sound, you will use the mid knob on the amplifier to adjust. One note is that you should not adjust this knob too high as it will create unpleasant sound. If you have a warm and thick bass voice, reduce the mid sound. If you have a high tone voice, increase the mid sound slightly.

Adjusting treble sound

The most accurate way to adjust Treble sound is to try singing through the microphone so that it is clear and crisp. If there is excess sound, it will be distorted and very harsh, while if there is insufficient sound, the output will be weak and not vibrant. If you have a high-pitched voice, lower the treble sound to balance the sound. For thick and bass voices, increase the treble sound to blend your voice better with the music. When you notice high notes in the music, adjust the treble sound clockwise. One tip for you is to set the treble knob at the 11 o'clock position when adjusting.

How to adjust amplifier for standard karaoke singing

Adjusting sound

First, to sing karaoke, you need to plug the microphone cable into the amplifier. Next, adjust the LO, MID, HI knobs to the 12 o'clock position. When adjusting the volume, turn the VOLUME knob. The most suitable range for this knob is from 11 o'clock to 1 o'clock.

Adjust Microphone knobs

To adjust accurately, you should turn on both microphones. Adjusting the knobs in the microphone area is done in the following sequence of steps:

Step 1: 

VOL knob: Test by speaking into both microphones to ensure the sound is just right for your audience. This adjustment is crucial because setting the volume too low will require you to sing loudly, causing fatigue. Conversely, setting the volume too high will result in distorted sound and annoying feedback.

Step 2:

PAN (or BAL) knob: This knob balances the sound between the left and right speakers. Keep this knob at the 12 o'clock position.

Step 3: 

LO knob: Try speaking the numbers '1', '4', '7' into the microphone until the bass sounds just right. Insufficient bass can cause the sound to be muffled. In this case, adjust the bass clockwise; if the sound is distorted or broken, adjust it counterclockwise.

Step 4:

Adjust Treble: Speak the numbers '6', '9' into the microphone until the treble sounds balanced. Excess treble can make the sound seem broken, while insufficient treble creates a lack of sparkle. Adjust clockwise until the treble sounds shrill, then turn counterclockwise.

Step 5:

Finally, adjust the midrange. Similarly, speak the sounds '2', '3', '5', '8' into the microphone to test, ensuring that '2' and '8' do not sound too muted or dull, and '3' and '5' do not sound distorted.

Adjust Echo Controls - Reverb Level

Adjusting the echo controls on the amplifier is straightforward. Begin by following these steps:

Step 1: Adjust the LO knob. This aims to increase/decrease the bass reverb of the microphone.

Step 2: Adjust the HI knob. You'll adjust this knob to increase/decrease the treble reverb of the microphone.

Step 3: Adjust the RPT knob (Repeat – this is the repeat adjustment knob): You should turn the RPT knob to the middle position at 12 o'clock and repeat about 6 times. This is a reasonable position to adjust the repetition of the microphone. For those who sing well, you can adjust it at 11 o'clock.

Step 4: Adjust the DYL knob (Delay – this is the delay adjustment knob): This knob adjusts the speed of the voice. This knob should be adjusted at 12 o'clock, or you can also increase it to 12:30 or 1 o'clock when you feel that your voice is slower than the music.

Adjusting Music knobs

VOL knob: This is the knob for adjusting the volume of the music. You can adjust the microphone volume slightly louder than the music to sing louder without straining.

LO knob: Sing into the microphone and listen to the sound output to adjust it accordingly, to avoid discomfort caused by feedback, balance the bass and treble levels.

MID knob: This knob helps to make the music sound clear, to avoid overpowering the microphone sound, you should adjust the MID knob between 10-2 o'clock.

HI knob: Used to adjust the treble, if the sound output is distorted or too piercing, you should turn the HI knob counterclockwise until the sound output is suitable. However, you should also adjust it moderately because if it's too low, the music will lack vibrancy and appeal.

Adjusting Master knobs – Total volume

VOL knob: Used to adjust the background music volume and microphone sound, the sound output from the speaker depends on this control knob.

LO, MID, and HI knobs: These are the knobs used to adjust the tone of the microphone. You only adjust these knobs when all the knobs in the MICRO section have been adjusted.

How to adjust the amplifier for the best music experience

To adjust the amplifier for better music listening, you need to adjust the LOW, MID, and HI knobs as follows:

LOW knob: Set it between 10 o'clock and 1 o'clock (depending on the type of music).

MID knob: Turn this knob to the 10 o'clock to 12 o'clock position.

What to know about adjusting the amplifier

• The HI knob in the micro adjustment area is essential as it prevents the amplifier from buzzing during karaoke. In case of buzzing, you should reduce the VOL volume knob or the ECHO reverb knob in the micro adjustment section.
• When adjusting the knobs, do it slowly and gently. If you turn them too fast and abruptly, it will create a buzzing sound that can damage the speakers.
• When connecting devices to the amplifier, make sure the devices are turned off to ensure safety. Additionally, to avoid overheating or magnetic interference that can degrade sound quality, do not stack devices on top of each other. Keep the devices at least 5-10cm apart to allow for proper heat dissipation and increase the longevity of the products.
• Poor-quality microphones are also a common cause of speaker buzzing or whistling. Therefore, you can choose wired or wireless microphones that are suitable to ensure the best experience.
