Are Genelec speakers damaged when the red light flashes or is on for a long period?
The speaker’s LED becomes red if the input stage is overloaded, the amplifiers overload or the driver protection activates.
No damage occurs in this situation. The protection circuitry protects the speaker very well from accidental overloading. However, when the red light is on, the audio signal has been modified to protect the monitor. Because of this, the speaker should not be operated so that the red light is turning on.
