I have some I-tech 4000's laying around, and could't find the All-pass filters in the dsp..
Anyone had this problem before?

I couldn’t find them either in my 8000 the other day. But to fair, the last time I accessed them was via a laptop and not via the front menu.

Without the architect software, you almost can't do anything with the dsp..

I generally use my LMS to make any filter adjustments.
My Itech is used for kick duty only.

I-tech series are Class I (BCA, Ballanced Current Amp). Is one very good class amplifier but if precision adjustments of underlap/overlap settings bad adjustment occurs, it could fail easy. I have repaired 2 pieces, is a good amp but it's limiter, personally I don't like, it allow for some small period of times HARD CLIPPING until it limits to a clean sinewave, ans as all "burst power amplifiers", cannot sustain declared output power for extended period of times, as "oldschool" amplifiers can do. Some tests here. Crown Macro-Tech5000i: And here another model but the same in most part, Crown I-Tech 5000HD:     Edited by DjLeco - 27 May 2018 at 10:21am |

So I've send an email to technical support from crown, and got a solution (hopefully).
Maybe that I have some time tomorrow to see if it works. I'll keep you updated!

To be honest.. I haven't tried yet, but I can send you the email chain they send me (with the solution ofcourse).

Just informing us in the forum should be suffice.

New question about the I-tech.
I've searched the internet to find more about the available limiting but have one question about the average power limiter. I suspect these are not the same as the powersoft counter part, also looking at the limiting for their JBL products I can't get any confirmation, knowing they rate the transducers differently. Drivers used with current limiting: BMS 18S430V2 126 Vpeak 300 Watt APL B&C 15NW76-8 85 Vpeak 150 Watt APL RCF ND950-8 (1.4") 28 Vpeak 35 Watt APL 12NW76/DE800 with passive filter (8 Ohm nominal) 85 Vpeak 150 Watt APL Calculation for Vpeak = SQRT(R*P) APL = P_AES/4 Impedance plot of all cabinets are planned in two weeks, so that would give any more info. Has anyone more experience with the I-tech limiting? I've found some stuf about the I-tech HD but it's different from the older I-tech.
