the cable used is interrupted (defective).
3. Ground loop (hum loop) "generated".
A ground loop can occur if at least two
interconnected devices with safety plugs

special "sheath current filter" (available from specialist
retailers) between the amplifier and the Soundbox 3 to
eliminate the humming. Turn the power plug round to
reduce the so-called hum voltage (particularly important
if the source device is not earthed).
