A DSP is already integrated in some amplifier models, otherwise they have to be purchased separately in the form of an external box.ĭepending on how complex the sound system is, it is important to ensure that it has sufficient number of inputs and outputs to pay attention to.

With the high-performance processors, it is possible to make runtime configurations and assign each speaker to a specific volume value. In addition, the frequency separation of individual speakers can be adjusted individually.Ī DSP is often used for complex sound systems and is used for acoustic fine tuning intended. The digital signal processing results in a loss-free listening pleasure. In addition, a DSP offers extensive setting options for high-pass and low-pass filters. With a DSP, numerous equalizer settings can be used for the sound optimization can be made. If you want to jump straight to the most popular brands, we recommend you take a look at: ESX, Ground Zero, DD Audio.Ī signal processor is inserted between the power amplifier and loudspeaker and digitally processes the audio signals in real time. By the way, the top sellers in this category are: DD Audio DSI-3, ESX DIRECTION D68SP, Ground Zero GZDSP 4-8XII. If the sound system in the car is to be tuned for maximum listening pleasure based on personal sound requirements, a DSP is exactly the right component to adjust the music reproduction to high-end level.
