We are frequently asked how to protect loudspeakers effectively via limiter. Most common loudspeaker controllers (like Omnitronic’s DXO-series) have an integrated limiter which is mostly not used or not used correctly.

In the following tutorial, we would like to show you how to adjust the limiter based on speaker-system and power amplifier.

For doing so, we need the following data:

– Speaker-system RMS-power and impedance

– Power amplifier voltage gain

As an example, we use several Omnitronic PAS-speaker-systems and the Omnitronic SMA-2000 power amplifier.

The popular Omnitronic PAS-212 has an RMS-power of 300 watts and an impedance of 8 ohms. By using the ohm’s law we can calculate which voltage is sent to the speaker-system at full output.

The formula is power P = Voltage U squared / Resistance R. By converting we get: Power P x Resistance R = Voltage U squared.

With values: 300 x 8 = 2400 Read more »

In the audio world more and more beats a digital heart – as in many OMNITRONIC products. Here is a small selection – if you have questions you can always contact our sales team.

OMNITRONIC EX-820 Digital-Effects-Mixer
