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.
The Signal Blender uses standard 9V center negative power, and has a current draw of 31 mA.
