You often need to send one signal to multiple destinations. Options for doing this include using dedicated multiples, free-floating widgets with multiple jacks wired together, or fancy cables that allow you plug one or two extra cables into them. The IV cable is one the latter: Made by Erthenvar, it has an extra 3.5mm jack molded into the mid-point of the cable (loosely resembling an intravenous or “IV” drip), in addition to having 3.5mm plugs at either end. It’s an alternative to the more expensive stackable cable made by TipTop.
