Protection circuit
The built-in power amplifier employs a
protection circuit to protect the
speakers if the amplifier malfunctions.
When a protection circuit activates,
there will be an abrupt loss of sound
from the speakers.
Particularly, when a speaker with a low
input impedance (less than 3.2 ohms) is
connected to the unit, the sound will be
discontinued. This, however, is not a
problem. If this happens, turn the
volume down a little.
If you have any question or problem
concerning your unit that is not covered
in this manual, please consult your
nearest Sony dealer.
