Hiya,
I'm hoping there is someone here experienced in creating speaker profiles in IRIS-net for importing into SONICUE (Both dynacord / EV software) . I'm trying to use a Dynacord LF1300D to drive my compression drivers and wanted to set the limiters.
Before purchasing I learned that it had adjustable limiters and was the only class AB amp I could find with them. But, today when trying to get it working I realise it isnt exactly "adjustable" as one would hope. The limiters have the ability to be changed but only by creating a speaker profile in IRIS-net software to generate a .sps speaker profile file. This then gets imported into SONICUE when setting up the amplifier and it applies all those settings from the file. In theory!
After a lot of faffing about and some help from google AI and a youtube video I basically know how to do this. However. What I dont know is how to calculate the threshold. There is a limiter threshold calculator inbuilt into IRIS-net which allows setting the speaker impedance, target watts, "amplifier type", and this calculates the target voltage and crucially the required DBu threshold. However, this calculation is based on the selected "amplifier type". It doesn't list the LF1300D, and if I click through the various listed types it changes the target threshold and by quite a bit, which basically means I'd be guessing = pointless.
Hoping someone can maybe assist here, or know of a better way, before this bloody amplifier gets thrown out of the window 🙄 I have to say though it is a nice sounding amp. I cant really tell any obvious difference when comparing it to my cambridge audio hifi power amp.

You should be able to find specifications for a listed amp with the same or similar voltage gain and swing as yours (32dB/55.3?) and get in the ballpark.
You should still verify when the peak and RMS target thresholds are exceeded the amplifier's output voltage and current is within the range you have decided is correct for your compression driver/horn impedance curve and target SPL.
