CA2600 includes a noise source capable of generating a spectrum of noise tones with a continuously variable control.
White Noise- Random noise containing all frequencies at relatively equal amplitude.
Pink Noise- Random noise with equal energy per octave. This has audibly more low-frequency content than white noise.
Low Frequency Noise- Random noise with an even stronger low-frequency bias than pink noise.
Out jack- The Noise Generator's output is normalled to one of the filter inputs, but the jack can be used to route noise wherever desired. Keep in mind that in addition to audio applications, noise can be used as a modulation source.
