Maximum short-term output level is limited by the PoE technology being used and the
crest factor of the audio signal. The stated values are typical for music and speech
signals.
Maximum long-term output level can be further limited by loudspeaker system protection.
Genelec recommends using PoE+ whenever possible. Using lower-power PoE can limit
short-term maximum and long-term maximum, depending on the characteristics of the
signal being reproduced.
User selectable filters can be set to positive gain. Positive gain must be used with care as
it is possible to cause premature overload of the loudspeaker at specific frequencies.
