• POWER HIFI
A hum is emitted from the
speaker.
The POWER HIFI is connected to
a different power circuit than the
rest of the system.
Connect the POWER HIFI and source device/
preamplifier to the same power circuit.
The hum is due to line distur-
bance.
Buy a line filter and connect all devices to it.
The humming is caused by a
multiple socket strip.
Use a different multiple socket strip or connect
the POWER HIFI directly to the wall socket.
