Signal Processors

Audio signal processors are devices used for changing the quality of a signal, or to simply alter impedance's and levels to suit subsequent equipment in the signal chain. Dynamic processors such as compressors and noise gates help to control variation in volumes, while equalisers effect the tone. Processors such as DI boxes and signal converters will act as interfaces between the 3 main analog audio signal types - microphone level, line level and high impedance (instrument) level. Other processors include devices that split or combine audio signals, for sending a single output to multiple inputs, or summing multiple outputs, for connection to a single input.
