All of our amplifiers use custom made transformers and are very quiet mechanically. All models are available in 100v (for Japan), 120v, and 220-240v/50~60hz (Europe, Asia, Australia).
Hum in the audio(heard through the loudspeakers)is usually caused by ground loops, poor shielding, system wiring, etc.
