KETRON 9V 40W is the original mains power supply for the Ketron Lounge, MIDJPRO, SD9, SD40, SD90 and Event arrangers and modules. The 9 V output and 40 W rating are matched to the current draw of these instruments, ensuring stable operation of the digital section with no resets, audio dropouts or interference carried into the audio path.
Stability for stage use
A mismatched supply is the most common cause of sudden arranger restarts while playing. The factory Ketron unit delivers power that matches the instrument's requirements exactly, so the device runs confidently even under full polyphony load with active effects. Clean, filtered voltage reduces mains hum audible on the line outputs, which matters when connecting to a mixer or PA.
Assured compatibility
Cheaper underrated replacements run hot and stress the instrument's power section, shortening its lifespan. This supply has correct polarity and a plug matched to the DC socket of the listed models, so it works immediately on connection with no risk of damaging the electronics. It is the choice for a musician who values reliability over saving on random hardware.
