Effects processor

Sound processors are secondary devices, usually connected in series with the main line of the signal, with the ability to switch on or off, and subsequently add a certain effect to the main line feed before main amplification occurs.

Effect processors come by the dozens with a myriad of different effects. Some popular ones include the D-Ser (to remove high frequency S sounds of the voice), voice enhancers, reverb, controlled echo, bass boosters and other forms of modulations. In reality even an equalizer is an effect processor, because of its ability to alter the original signal.

In general, effect processors tend to have a low impedance to the signal and therefore add minimal noise to the line. However, because effect processors are always in series, the noise component of each processor is cumulative to the rest of the line noise, and hence, the more processors you add, the more noise to signal ratio you get. Ironically, there are even effect processors that claim to remove line noise and give a cleaner signal. Such claims are often hard to believe, because by their very nature, processors add noise and indeed if you want a cleaner line signal, add less, and certainly don’t add noise reduction processors.
