7 About the Protective Circuit
This unit incorporates a protective circuit that
protects the amplifier circuits and speaker
system against damage.
As soon as the protective circuit works, the unit
goes into standby mode and the STANDBY
indicator flashes at the same time.
¶
For power-on
For 3 or 4 seconds after the power of the unit
is turned on the protective circuit works and
the sound is muted. Once the amplifier circuits
are stabilized, the protective circuit is released
and the sound is restored.
¶
For heat-up of the power amplifier
When the power amplifier of the unit heats up
under the following conditions, the protective
circuit works and the unit goes into the standby
mode.
•
The unit is kept used with excessive signal
input, and the temperature of the main
amplifier section exceeds the set operating
temperature.
•
Since the ventilation holes at the rear of the
unit are blocked or the unit is installed in a
narrow rack, the internal temperature of the
unit exceeds the set operating temperature.
In this case, wait until the temperature is
sufficiently lowered, then turn on the unit and
operate it at a lower volume.
