A piece of equipment that changes the audio in some way. Example: Reverb, Compressor, Limiter, Delay, etc.
A device used to change the character of an audio signal. Compressors, limiters, expanders, effects devices.
1. A signal processor 2. A device matched to a specific loud speaker (or group) to make the speaker(s) sound as good as possible and/or protect the speaker(s) from audio signal not suitable (i.e., too loud) for the speaker.
A device which modifies an electrical signal, usually in a dynamic manner. In wireless, sometimes used to refer to companding.
A device which affects the whole of the signal passing through it, e.g. gate, compressor or equaliser.
In CATV, a headend channel control device that receives a TV channel at RF, cleans up the signal at IF then converts the channel to a desired frequency and outputs the signal at a controlled level to a combining network and into the cable system.
A device in headend which downconverts an input signal to an intermediate frequency (IF) for processing, then upconverts that signal to a desired output frequency.
Device designed to treat an audio signal by changing its dynamics or frequency content. Examples of processors include compressors, gates and equalizers.
