1. Continue to use the PA speaker
after it is damaged
If the speaker system is damaged because you overuse it, but you don't know and you're still using it, please use your ears as a guide. If you hear distortion in the clean inputting, the speaker may be damaged.
2. Signal clipping occurs before the signal reaches the power amplifier
This is caused by improper mixer gain distortion or too hot level signal.
3. Speaker transient heating
Transient heat is caused by power outages and microphones input/output or other reasons.
4. No enough power margin
If your PA power is too low (not enough free space), the clipping will occur. So, your speaker will be damaged.
5. Incorrectly using compressor/limiter
Your music life and speaker life will be reduced by excessively compress and limit!
6. Excessive EQ
The outstanding "smile" curve is actually the devil's laugh at for your speakers! Remember that EQs are best used for clipping, not for strengthening signals. Do you need higher sound? Then please reduce bass…… Do you need bass? It is OK to just lower the pitch.
7. It is best to install an outdoor device matching your indoor system
Outdoor device requires at least 12db (16x power), more volume outputting is needed than that for indoor device, preferably 20db (100x power!).
8. Speaker systems that SPL requires are not enough or the coverage is incorrect
Instead of using relatively high voltages on the same speaker device to meet the required SPL, we need to add speakers to get more amplifying channels.
9.Improper dual speakers: the crossfader is too low or the high pitch amplifier is too high
When conducting two-way amplification, you should always check the specifications of your speakers and adjust to the most appropriate crossover frequency.
10.Frequent bad feedback
If there's a long, sharp sound in the feedback after you say "ouch," your speakers may be broken! If you're using the broken speaker, it will be even worse.
