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
Active ABY in either direction
Volume level setter
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.
