About the input over-voltage
protection circuitry
The speaker system has a built-in input
over-voltage protection circuitry for the
tweeters. If an excessive input signal is
applied to the speaker, the protection
circuitry works to cut off the signal input
to the tweeters.
A sudden drop of the volume level in
high frequencies during speaker
operation indicates that the over-
voltage protection circuitry has been
activated. In such a case, reduce the
amplifier volume and wait.
The protection circuitry is automatically
reset in approximately 10 seconds.
After the situation returns to normal, set
the volume at a level lower than before.
