To make simpler the limiter threshold setting the following table can be used:
SOME TIPS
• To protect the high frequency drivers from dangerous feedbacks in live environments we suggest to set the limiter
3 dB under the calculated value.
• When you push up the volume of your system you can notice that the low-mid content of the program is usually limited
before the high-mid content. This is due to the fact that low frequencies activate the limiter before high frequencies,
with the result that the system can sound very harsh. In order to restore the original sound balance you can set the HF
driver limiter threshold a few dBs (usually 3 - 6) below the calculated value.
