4-Channel Quiet Switch PUBLIC

Circuit enables / disables separately any of 4 different channels.

This circuit allows a guitarist to enable any of a set of four channels with separate inputs and outputs. For a single signal source, use a 1-In 4-Out signal distribution circuit or simple passive splitters. The outputs go to different effects, effect-lines, amplifiers, or other active electronics. Example: Straight guitar signal in Channel1 constantly on, while the other channels are for effects devices. The four final signals are combined in a mixer with at least four high-impedance inputs, where its output goes to a guitar amplifier. Note that this is an untested experimental circuit, designed based on datasheet application information for the ICs, and should be breadboard tested before committing to soldered build. For exclusive enabling of one channel while all others are automatically disabled, see the project labeled "1 of 4 Exclusive Selector Circuit", also an experimental design. Possibility: For 16 channels, use one of these circuits to control four separate 1 of 4 Exclusive Selector Circuits.
