Heco Aleva GT Center 32 - Manual (Page 9)

If the output of your amplifier is significantly higher than the rated power handling capacity of your
speakers extremely high volumes can physically destroy your speakers. This doesn’t actually happen
often but you should be aware that it is possible.
Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium
volumes because weak amplifiers may overload much faster than powerful ones and this causes
measurable and audible distortion, which is extremely dangerous to your loudspeakers.
Always turn the volume down immediately as soon as you hear distortion! If you like listening to loud music
make sure that your amplifier can deliver at least as much power as the speakers’ power-handling rating.
THE SoUND YoU CAN’T HEAR...
Amplifiers, tuners and CD players can all produce inaudible high-frequency signals – and this doesn’t
only apply to cheap products. If your tweeters fail at low or medium volumes you should have a qualified
technician check your system components for dangerous inaudible signals.
MAINTENANCE
The surface is best cleaned with a mild household cleaner. On no account use furniture polish or similar
products.
