The world of Sound is vast, so are the audio processing equipment. In order not to get lost in the matrix of poor quality equipment of unknown origin, choose genuine Midas, Klark Teknik, Behringer, Denon, TC Helicon, TC Electronic sound processors.
Learn about signal processors in sound systems
In large and small music events, the use of audio signal processing equipment is extremely necessary, to help you have a fuller view, we would like to share some information about the instruments. Signal Processing. In order not to get lost in the matrix of poor quality equipment of unclear origin, please choose genuine Compressor/Limiter,Effects, Crossover, Microphone Preamps, Feedback, Equalizer, DSP, Mixer from manufacturers Long-standing names such as
Midas,
Klark Teknik,
Behringer, Denon, TC Helicon, TC Electronic are imported and distributed by Hoang Bao Khoa company with the best price.
1. Mixer (audio signal mixer)
The main feature of the mixer is to connect, mix the input signals, process and transfer them to other devices such as power amplifiers, recording devices, etc. Input sources such as musical instruments, microphones, etc. have very small signals. Therefore they need to be amplified to reach the standard level in the sound, or reduced in case the input signal is too large to cause noise, This input signal adjustment feature is built into the mixer, usually through knobs or faders to perform audio signal processing functions. Midas M32 Live is a Mixer favored by the ProSound brothers.
2. Effects (Effect Generator)
Have you ever wondered why some singers who sing on youtube so well are not born as good as they are? The simple answer is that they used the Effects set to create more vocal effects, of course having a good voice would be better, but the Effects set could not turn a grass duck into a swan within 1 note. Common Effects sets are Behringer FX2000 Effect, M100 - Effects and Signal Processors TC ELECTRONIC M100, PERFORM-VG -- Voice Processors
TC HELICON PERFORM-VG
3. Equalizer (audio signal filter)
EQ has a general function of adjusting the tone of the sound system. EQ allows users to increase and decrease the frequency ranges of the audio signal from the mixer to the equalizer, from 20Hz-20kHz, within the range of the human ear can hear.
In addition, the equalizer is also used to adjust the timbre of the input signals and the speaker's ability to suit the space used, the sound is beautiful, clear, without hissing or howling.
Each sound system usually has 1-2 equalizers to adjust the timbre. However, at present, the actual need to adjust the timbre separately for each input device is different such as: microphones, musical instruments and background music... Therefore, for large sound systems, many people prefer to use the digital mixer type. These types of mixers have built-in equalizers and allow each input signal to be customized with a separate equalizer to create the best sound effect. Pictured below is the Klark Teknik DN370 from the UK, the legendary EQ.
4. Crossover (speaker crossover)
The output signal is only one, but in many cases, the sound system includes many speaker clusters with different functions:
- speaker system for high, mid, and bass
- subwoofer system
- monitor speaker system...
These speaker clusters have their own strengths, divided into a certain frequency range for optimal sound quality. Therefore, it is necessary to have a crossover to divide the frequency for each speaker cluster according to the ability and purpose of use.
Depending on your needs, you can choose from different frequency converters. For bulky, complex analog rigs, you have to divide into 3 separate processors. But modern digital technology makes it possible to integrate all these features in just one device.
5. Feedback (anti-howling kit)
The sound system appears howling due to the position of the microphone close to the position of the speaker. When you sing, the microphone records and emits the speaker, accidentally the sound emitted from the speaker is recorded by the microphone and amplified exponentially. This creates many such cycles, causing the microphone to be howled. An effective way to combat howling is to cut off the howling frequencies by using the Behringer FBQ100, FBQ1000, Klark Teknik DF1000 Feedback Controllers, then the Feedback unit will automatically detect the howling frequency and effectively suppress it.
6. Compressor/Limiter (audio compressor/limiter)
Compressor/Limiter is used for the purpose of limiting the audio signal beyond the allowable level, especially for bass, treble. When an active audio signal is amplified and transmitted to the speaker, it will often be distorted within a certain range, causing unpleasant sounds to the listener's ears. And the compressor/limiter cuts frequencies beyond the user-defined audio threshold to overcome such cases.
Due to the growing technology, now the majority of sound systems use digital signal processors (also known as DSP–Digital Signal Processing) with a wide variety of input and output connections and capabilities. Multi-tasking audio signal processing such as Equalizer, Compressor/Limiter, Effects, Delay, Crossover etc. for separate outputs for you to arrange your sound system professionally and more efficiently. DCX2496 Behringer Signal Processor, Lake LM Series or even a very cheap small digital mixer like Behringer Flow8 also have all the above functions to allow users to adjust the sound in depth and most conveniently through software. .
The above is the function of the signal processing devices in the sound system. For detailed information, you can visit: https://hoangbaokhoa.com/signal-processors.php or call Hotline: 0799030088 - 09094 777 88. Hoang Bao Khoa's technical team will answer all your questions.
