Hello,
The timing settings you asked are different for every speaker and also if you biamp them or not, so could you please describe your rig in more detail.

Doesn't matter for which i-Tech the settings are for, just the speakers, so for the JBL SRX725:
Peak Limiting voltage = (SQ Root (2)) X SQ Root (Peak speaker rating * speaker impedance)/2= SQ Root (4800X4) X 0.707=98V

Continuous/RMS limiter setting for the 725:
1200W/4 (to get 12dB)= 300W

Dear dakos,

may i revive this thread asking how to adapt the mentioned JBL SRX 725 to the LevelMax Funktion of the I-Tech HD's?

The values known&given for the 725s are RMS/Program/Peak 1200/2400/4800 on 4 ohms.

The values needed for feeding the LevelMax are AES Power/WRMS 2h and 100h. Is there a way to translate the RMS/Program etc wattage into the values in question?

thanks for any support :-)
Carsten

Deat Carsten,
Not that I know of. You would need to contact JBL directly for those figures.
Another option would be to load the presets for the srx to the itech HD and see what JBL put there if they did ake presets for the SRX for the HD amps.

Let us know what you find out.
