When used with optional PVi4B amplifier, the LL9816 (and it's heavy-duty caged LL916 counterpart) is capable of filling a 25 yard olympic pool with sound for lap swimming, a 50 meter Olympic pool for synchronized swimming, or a 500 meter distance in the open ocean for experiments. No other brand compares! The LL9816 is provided with audio isolation transformer box with cord (see below), ready to connect to optional PVi 4B powered mixer & accessories.
