Signal Processors

A signal processor is inserted between the power amplifier and loudspeaker and digitally processes the audio signals in real time. With a DSP, numerous equalizer settings can be used for the sound optimization can be made. In addition, a DSP offers extensive setting options for high-pass and low-pass filters. The digital signal processing results in a loss-free listening pleasure. In addition, the frequency separation of individual speakers can be adjusted individually.
Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like “add”, “subtract”, “multiply” and “divide” very quickly.
Signals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be of use. In the real-world, analog products detect signals such as sound, light, temperature or pressure and manipulate them. Converters such as an Analog-to-Digital converter then take the real-world signal and turn it into the digital format of 1’s and 0’s. From here, the DSP takes over by capturing the digitized information and processing it. It then feeds the digitized information back for use in the real world. It does this in one of two ways, either digitally or in an analog format by going through a Digital-to-Analog converter. All of this occurs at very high speeds.
Depending 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. Most DSPs have four to six inputs in the form of RCA or high-level connectors. On the other hand, there are typically six to twelve RCA outputs for a multi-channel loudspeaker system.
