That link you provided can't even provide a secure connection (no recent cipher) that it can be browed with a modern browser so that speaks volumes to the lack of attention to detail the company has.   I can't imagine they are capable of designing an audio system. 
You seem very married to QSC.  It's decent stuff but can't you get Yamaha or JBL?  The Yamaha tops are worlds ahead of the QSC for the same price.  I run Yamaha DSR112 over QSC subs.  I moved all my K and KW inventory to monitor duty.
As far as the Touchmix it is ok, it runs sluggish.  So many better mixers on market.  Can you get Allen and Heath or Midas?
The PA2 processor completely sucks.  They don't begin to unsuck until you get to the Venue 360 model.  The Zilica you mentioned is light years ahead.
You spoke of taps.  Taps only matter if it supports FIR filters.  If this feature is important you need to check closely.  Also speakers like the QSC have built in DSP not sure what you need a processor for.

This seems like they have a new website however I can't find that model perhaps its old stock. LA122 but thats the only model he can get anyway, so no point in looking in through the new website for decent options.

QSC seems like the only normal brand in the country that is floating around for rental. There is JBL, but he only has VRX but I can check what else he has in the JBL range, the actual venue has one of the PRX series but there awful, subjective i know but i mean you can hear the dsitortion. I don't think he can get Yamaha but it must be available in the country, I can check and I will look into your mention. As you can see there isn't many options however, if I can, I will perhaps try and work with another sound engineer/renter with other models if better models exist that is.

Venue360 or Silica better bet, thanks so much.

Great to know the QSC has DSP but not sure if the K118 subs do. Would the QSC touchpro manage filters for the dual sub? If the QSC touchpro is okay for this one time rent, then I can or the owner can pay for a proper sound system designer if he wants to purchase a proper sound system.

Coiming from small room acoustics and sound sysstems I thought it goes without saying that DSP needs FIR filters, I thought anything less would be obselete.

Regarding the other mixers you menioned, I doubt I can find those brands in the country so for now perhaps I go with the QSC touch mix pro. But in saying that I will look for other brands that are available outside of what this particular guy can organize. And if its better than for this one off rental it might be beter to go with something a touch better to prove that decent soud can be attianable.

One big advantage of a passive system, is the room (permanent) DSP can be in the amps and not available for adjustment by the engineer du jour.
BTW, where are you located?  For high quality pattern control Danley Sound Labs is hard to beat.  There may be a dealer or provider nearby.

As Brian pointed out, much of the same processing found in a system processor or DSP in the power amp is also available in the mixer's outputs. Even though you have the system processor or amp's DSP locked down, one can still wreak havoc with the processing available in the mixer outputs, but now you are adding EQ on top of  EQ, compression on top of compression, etc.

Masis, All QSC K Series have the processing needed to maximize the performance of that loudspeaker.  They do not have accessible DSP for room equalization.  The Touchmix series does have some DSP available for room equalization and to tune the system to your taste.
 
The technique I suggested was for a "throw and go" event.  This is not a substitute for equalization that can be done using systems like Smaart Live and the advanced DSP processers other have suggested in this discussion.  As has already been stated:  Equalization and DSP used the wrong way can really screw things up.  Just be aware.

The feedback filters I mentioned are found in the "Feedback Wizard" section of Touchmix mixers.  Good luck!

FYI,  it’s Zilica not Silica.  You are in EU why can’t the gear you want simply be shipped?

I think you are over complicating this.  The DSP in the speakers (including the sub) is there to get the most out of the drivers and enclosure. 

Any room tuning can be done in the board.  You don’t need FIR at this level.  If the speakers need it then it will be utilized to best tune the speaker.  It is not accessible to the end user.

I do not endorse recommending this level of processing to Masis and expense at this point in the learning curve.

[Masis Ingilizian]

Firstly thank you everyone for there effort and responses, I have synthezised all the posts and my understandng is the following.

1. An outboard DSP is necessary for a proper sound system rig in future.
2. However, for this one off rent, "throw and go event" the QSC mixer with the speaker DSP is enough to get the job done.

This is enough for me, but I have learnt a lot and will use this thread for future.

What I will do is start another thread to ask a few questions about equalization, nothing too complicated just to get my the basics that I think I know and ensure that the sound check guy on that day is going about it correctly, like i said best case scenario is that he knows what he is doing.

My last question for this thread is simply, if in future the owner is ready to purchase a sound system, how much more would a sound system designer offer considering that the venue needs a simple point source and that there is sound engineer setting up most of the stuff? Can Ease Focus be enough to simulate and ascertain the basics or does a sound system designer of course with the calibre of experts such as the one on this forum provide a hell of a lot more? I only ask this becuase I dont want to recommend it to the owner if I can't gaaruantee it will be better than the sound engineer who organizes his equipment. If you know what I mean....

^^^  Masis, this can be summed up very easily.  "You will get the results that you pay for".

Generally speaking, external DSPs are well in the camp of «buy once, cry once».
I still have and use the first Lake I bought back in 2009. Various other cheaper dsp’s came and went over the years before I finally bit the bullet and bought more Lakes.
Could have saved some cash right there…

I've done that same dance many times as have most.  Buy the good stuff - in the end it's an investment - even if you take another path, it holds resale value.

There are times when you simply have to arrive at the doorstep of "The Good Stuff" as one learns.  I'm on my 6th, 7th or 8th air compressor in the shop - lost count.  Now it's a 10Hp EMAX Silent Air.  Plenty of air, great startup and recovery time.
