How to adjust anti-feedback digital reverb extremely simple

The sound experience of a karaoke system will often be incomplete, even annoying if the microphone howls. This is also a common problem in karaoke systems today. This problem can actually be handled in many different ways, including by adjusting anti-feedback digital echo Simple can also fix the problem of microphone howling. Not to mention, adjusting the digital echo properly also helps the sound experience become gentle and smooth.

1. Basic parameters in digital echo system

Basic parameters on the digital echo system need to be adjusted to prevent simple feedback

To be able to proceed with the adjustment anti-feedback digital echo First, users need to have a certain understanding of some parameters of the digital reverb. Each different parameter will ensure different adjustment conditions. Based on that, users can customize the sound in the best way. Currently, the parameters in the digital reverb are often divided into different groups, including:

Micro Group

- Mic Echo Level: Mic Echo Level

– Mic Direct Level Direct: Direct sound of the microphone without processing

– Mic Reverb Level: Increase or decrease the microphone echo

– Mic Direct Level: Brightens the Reverb echo

Echo Group

– Echo HPF: Cuts low frequency echo

– Echo LPF: High frequency echo cut

– Echo Pre delay: Echo before delay

– Echo delay time: Echo delay time

– Echo Repeat: Echo repeat

– Echo R CH Pre Delay: Echo of R channel first, delay after

– Echo R CH Pre Delay time: Pre-delay time, post-reverberation

Reverb Group

– Reverb HPF: Cuts low frequency echoes

– Reverb LPF: Cuts high frequency echoes

– Reverb pre delay: Reverb first, delay after

– Reverb time: Reverb time

Some other important parameters:

– Hi EQ: High sound

– Mid EQ: Adjust midrange at +/-15Db

– Mid Freq: Determines the frequency for midrange from 100Hz-5Hz

– Low EQ: Adjust the amount of bass increase or decrease

– Mute: Mute

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.

3. How to adjust digital echo to prevent feedback simply and effectively

There are many different ways to fix the problem of microphone howling, but simply applying a simple digital reverb adjustment will also limit this problem. How to adjust anti-feedback digital reverb It is relatively easy to do and the result is no annoying howling or screeching noises.

Step 1: Point the microphone head straight at the speaker and slowly increase the microphone volume until the speaker makes a howling, screeching sound.

Step 2: Stop increasing the volume and decrease it by 1-2 numbers until the microphone stops howling.

Step 3: Adjust the frequency bands that cause howling noises on the digital reverb, specifically:

– Howling appears at frequencies of 20Hz-200Hz in the bass sound

– Hissing sound appears at frequencies 6kHz-20kHz in treble

Step 4: Identify the howling and hissing sound in the appropriate frequency range and use Equalizer (EQ - audio signal balancing device) to cut the frequency range where the howling and hissing sound appears on the digital echo. Or you can lower the frequency range where the howling and hissing sound appears on the digital echo when checking the microphone.

In fact, current digital reverb lines are integrated with automatic anti-feedback feature. Therefore, users do not need to manually adjust the digital reverb to experience the best sound.

The best way to avoid the hassle of editing anti-feedback digital echo but still have a quality sound experience, users should choose to use professional, genuine karaoke audio equipment at reputable stores.
