Just recently, During a modeling session. I have come accross a strange thing happening to my speaker models. If I click 'All to Max' on the speaker power selection, It does not select the max power available from the speaker model. I fI use the +1 button, all numbers turn to red and then Check Data says speakers are over powered. This even happens to the Sphere.. Crazy..

I have never had this happen before... This doesn't happen on other model files, only the current one I am working on.



I deleted all my speakers in the model and started over but nothing will power correctly now.

Help...


Thanks,

Brandon

Brandon,
I've also had this 'problem' with v4.3
What I've found is that the loudspeaker manufacturer's data has had some errors.
For example for a max input power of 1000W, the max SPL was approx 30dB with sensitivity values of between 0 and 4dB!
Have a look at the .spk file of the loudspeaker you are using - you might find some values are too low.

In my situation, I e-mailed the loudspeaker manufacturer who prompty amended and reissued their data.

Hope this helps
Regards

Tim, Brandon,

Have you tried opening the Room Data -Settings? EASE v4.3 has a default selection of broadband pink noise calculation, which I found out if this is the cause of this over power problem. Try to switch it to multi tone calculation.

Please see the post here:

If you want weightings to work, you'll want to switch back to the pink noise metaphor.
