KEY Active systems
D) PROTECTION LED: This led lights up when the amplifier is in a protection
situation (such as temperature excess, overcurrent, or other situations that can
compromise the amplifier's integrity).
It will also light up when the amplifier is in standby mode. This happens for a couple of
seconds at startup.
The Protection led will light off when the amplifier recovers from the abnormal
situation. Shall the Protection led keep up lighted on even after a system restart,
please contact an authorized service.
E) LIMITER LED: The limiter led lights up to indicate that the amplifier is delivering
the maximum power set by the limiter circuit. In two-way bi-amplified systems, this
LED will light when either of the amplifiers is limiting. The limiter prevents the
loudspeaker from receiving excessive or distorted signal. Continuous lightning of this
led indicates that the signal is being massively compressed. In this case, the input
level should be reduced in order to get a proper dynamic headroom.

- Model reference
