Power handling
Each amplifier or receiver used at high power over a long
period of time can produce distortion which may seriously
damage your speakers.
Your ears will warn you, since the speakers will indicate
overloading by giving distortion.
If this happens reduce the volume and tone controls to a
level where the sound is acceptable again.
When using microphones, avoid microphone feedback
which occurs when microphones may pick up sound from
the speakers, resulting in a dangerous howling sound.
Keep the microphones away from the speakers of reduce
the volume.
Note:
– Speakers are most often damaged when they are
overdriven by under-powered amplifiers. The clipping of
the amplifiers will damage the tweeters.
