System devices, the audio signal processing components are indispensable in a sound system. Currently, in the market, besides the sound signal processing as equalizer, crossover, … but now the manufacturer launched the digital signal processor, also known as DSP (Digital signal processor), with much greater convenience and most especially in audio signal processing more accurate.
Some devices such as equalizer, crossover, limiter … very familiar to those who play audio. There’s also the sound effects generators: delay, echo, reverb … Technology brings growing equipment more modern and easier to use. If before you have to use the device handle analog signals, ie for example want to “cut” the specific frequency, you’ll have to manually adjust the equalizer on the corresponding needs, then now you have can do this through the DSP digital signal processing via software on a computer, can be saved for use when needed easily. In addition, devices such as crossover, limiter, … are integrated in this DSP. Let’s look at an overview of device DSP digital signal processing below.
1. The concept device digital signal processing DSP
Equipment for processing audio signals digitally DSP (Digital signal processor) is the audio signal processing integrated many features, and you can adjust through the software provided by the manufacturer on board computer, phone. These functions and utilities featured devices generally include:
Divide the frequency range for the subwoofer and speakers full (2 way, 3-way, …)
Balancing timbre (equalizer function) to the speaker to suit each space (indoor, outdoor …).
Audible limit, protect your speaker system.
Phase Island Sound to help eliminate or resonant sound.
Delay (delay soup) for the sound of the speaker.
Also depending on the equipment of different manufacturers can come to add some other features to meet certain specific purposes that the manufacturer wants, but taken together, the type DSP (yes some people called a controller) will have the basic features listed above. And say as described by some manufacturers on their product that’s DSP DSP as GPS (navigation systems) for your audio system, always tell you (your sound) is in Where (and how). It will help you improve the sound quality up to a fast and accurate way.

2. Application of the signal processor DSP digital sound
The signal processor DSP digital sound can be applied suitable for most stereo professional performances, from the indoor unit in the hall, restaurant weddings … until the orchestra sound rental, game shows, professional events, karaoke.
DSP devices typically have relatively high trade costs. Therefore, it may be obstacles for some people. Some people choose to buy individual devices by function for your stereo like equalizer, crossover, effect … However, this is not the best choice and the best choice. Some people have knowledge of sound can be adjusted once this device is quite easy. However, in order to coordinate them is not simple. Another obstacle is that each time changing the space, you would have to “set up” the sound quality to match. Especially with cases sometimes there will be users and customize your sound system, and they will also scaled to suit your headset, and then you would have to “start over “the work aligning each signal processing equipment.
When you purchase individual devices such as fins leave, they take up space, space, and need multiple wires, hard to handle when there is a technical malfunction. The cost of buying each device can equal or more leaves at higher DSP processing equipment if you started from the beginning.
When you use the appliance digital signal processing DSP will solve these problems. The functions to be tweaked on the computer should have a very high accuracy behave. You can save the configuration on each case, to change space when you can handle easy.You can also customize directly on the device as the analog signal processor in single cases Simple, no need for a computer.
Devices DSP digital signal processing so many people today use the information. However, depending on the preferences of each person, you can still use the device handle analog signals earlier if it is consistent, effective, and use DSP as a way for you to overcome any convenience and increased efficiency and quality for your audio system.
