A POWER (or PWR IN) 2-pin connector enables the use of an auxiliary Power-adapter unit for the BUS to supply the PW1 signal when the selected operation is NT simulation.

For Clarinet Book USB type, the PWR OUT -> PWR IN wiring can also be used if the external Power-adapter unit of the Clarinet-Book is connected.
