The colour of digital noise is different from analog noise. The internal clock range is about 50Hz to 40kHz. For this the "XClk" socket is provided. As soon as a patch cable is inserted into this socket the internal oscillator is turned off and the signal applied to the XClk" socket is used to generate the noise instead of the internal clock signal.

The noise signal is generated 100% analog by amplification of the noise of a transistor. The A-118 gives you the ability to mix the relative amounts of Red (low frequency component) and Blue noise (high frequency component) in the colored noise output.
