The Signal Blender provides a number of parallel routing solutions through its use of a pair of send/returns, primary input and output, switching, and volume control. Signal Blender can be used as a parallel effect blender, 3-to-1 mixer, 1-to-3 splitter, active ABY in either direction, volume level-setter and more. A courtesy 9V power outlet and phase correction switches for both Sends add further versatility to this box. Clever switching allows for latching or momentary on/off action with trails.
