HeyDakos!

Very interesting thread going on at PSW. The device file for the preset is linked to the 2nd post in this thread and over at PSW also.

Thanks as always!

For those interested, the Device file. ITech amplification, 4K. Preset number 9.

Thanks again!

Yes,

The X32 is a surprisingly capable mixer, and if we go with the 2 x HD12K's, instead of 4x MAi's, we have sorted our DSP problem also.

So it would start looking like this :

1. 4 x STX835. 2400w Programme per box.
2. 4 x STX828. 4000w programme per box.
3. 2 x IT12K HD. Each channel driving 3750watts into 2ohms.

Not ideal, but should get the job done atleast to Xti6K levels ?
With a future upgrade to add 2 x IT5000 or 9000 HD amps for the 835 boxes.

Avi, thank you, as always!

Hey Avi!

My Bad. We are looking at a total of 8 boxes. 4 x 835 and 4x828.

Now, possible, for a start. To run these boxes at 2ohms, using the IT12K HD. And then at a later date get a couple if IT5/9K for the tops. Then running the whole rig at 4ohms.

Ill be happy giving these boxes programme power over Peak power.

Thanks as always.

Hey Avi,

2nd hand gear is an option, but very avoidable. China is next door, and most 725's aren't really 725's anymore.
However, used DR260's could probably be found. Im not very sure of the 260 sound. It is a very dated product.

My immediate alternative. The X32 mixer has filters available on all its Matrices that go up LR24db slopes. So that is an intermediate solution.

Then I would like to essentially have something which JBL develops presets for. And currently there is no standalone DSP unit they are doing that for. Only Xti's and the IT HD's. The Xti's are not powerful enough, and the HD's quite expensive. Still, my impression is that the presets are essentially eq curves, as the boxes run passive. And should not be hard to replicate.

If I manage to get a system voicing sounding similar to the v4 presets developed for the STX range, then I will run this rig and do an AB comparison using analog crossovers and outboard eq vs. Itech HD with the presets.

Im very surprised that you consider the SRX to be sonically close to the STX. That is not what I heard. I did a STX825 vs. SRX725, and the difference was quite a bit. Granted, was running the JBL preset through an IT HD driving the STX, the SRX was running without any DSP.

I think ill hold out the DSP purchase for a bit.

JBL is the dominant brand around here, where D&B making strides into the upperend. Everybody has some SRX boxes. But we are so tired of the lack of consistency with the JBL boxes of the same type  (not JBL's fault), that we have now decided to go get our own.

The IT Hd amps are way more expensive than the MA series + a BSS Omni/minidrive combo. And since we are looking at a total of 4 boxes, with 2 MA5K and 2 MA9K's, we still only need to get 1 x 366 or the DR4800. None we can afford right now.

Thanks as always. Ill keep you posted.

Sidhu
