Niles GXR2 vs AMX Precis ?

My Understanding is that the Niles has a slow change time and can only work with one zone at a time. ON the other hand it does have meta data. Does the precis change zones or at least react faster to touchscreen commands?

The Precis is just a switcher. It is definitely quicker, but you also need amps, and you need to add device control and controllers for each room that the GXR2 package already provides. I don't really consider the products interchangeable - they each have their own applications and not a lot of overlap.
I don't thinkyou meant a different ni 2100 or whatever per touchpad , but maybe you did?
Thanks, mark
I mean that you assign a Niles RS232 box for each AMX touch panel that will control the GXR2. That way, individual panels can control separate zones at the same time. If you only have one, it can only be active in a single zone - which means two people in different rooms are going to have a conflict. One of them is going to lose control to the other.
We just met with the Niles product developemt manager for the GXR2 a couple weeks ago concerning the control of the product. We showed him how the control architecture was just plain screwy.
It's effectively very slow, does not volunteer feedback on zones that your're not 'looking at', takes an undesireable time for you to change zones and solicite feedback, and even then can send out erroneous feedback messages. Current Volume of a zone seemed to be very unreliable. You'd quite often get 'zero' or the level of the previous zone you were looking at.
It's not slow in and of itself. It's just how they choose to interface with the outside world. Their method is basically that you send it a request to look at zone #X. After that all commands to and feedback from is meant for that zone only. If you were looking at zone 2 and got some feedback and then sent a zone 3 command, it seems to take the thing a while to get used to it. You'll get some zone 2 feedback when you're expecting zone three. There's nothing in the feedback protocal to indicate which zone the feedback pertains to. You're just supposed to know that from you sending the zone request command.
Once you are firmly established within a particular zone, the feedback seems to settle down and work fine. It's when you try to poll all zones or move from one zone control to another that things get pretty sketchy.
He seemed rather interested in how we controlled other devices with similar feature sets. Of course, we left on a very positive note and with promises of better stuff coming soon. The skeptic in me tends not to trust it all.
We'd love to use the GXR2 in our smaller systems. But, for now, we just can't rely on them to perform with other control systems clam-shelling over them.
When it's the only control system in play, it works very well.

I like both the Presis and the Extron. We use them both and have had great results. They both are easy to program and pretty bullet-proof.
I like the fact that the Presis has built-in processing. You can adjust pre-gain and EQ settings for each zone.
The Extron has balanced audio ins/outs and that also is great.
We also deal Elan and have had good results there too with the S12.
Yes, but the way we design these things, the GXR2 is really the main multi-room controller. The AMX system is usually a local theater or TV room that has the GXR2 as an input, so it needs to control it from there. So at most I'll have 2-3 RS-232 boxes on a full install, with Niles Contact panels on the rest of it. If every room were to have an AMX panel, I don't think I'd use the Niles, I'd go with a straight switcher and control the sources directly.
word...
I suppose it's my own bias chiming in since we typically never do systems like that. There's not much middle ground for us. we either go very simply or very expensive.
That's what happens when your designer/sales people are rather impatient...
In this system we have a 3100, 3 x 8400s (if the 5200 comes out by June and we have positive feedback then 1 x 8400s and 2 x 5200s) and 5 x R4s.
Would I need 8 x Niles RS232G to have proper control of the ICS system from the AMX touchscreen and remotes?
I would like to offer the client full control of the ICS system, something similar to the touchscreens examples in the new AMX home brochures, http://www.amx.com/amxhome/mktmaterials.asp .
We have a Precis component and analog audio switch specified as well but I think using it for the ICS audio, things will get very complicated.
Sources would be 4 x analog or digital sources (cd, dvd, tv and sat), ipod and one server which is either request or kaleidescape.
I was also wondering if we can have proper ipod control through the ICS system and the RS232G on the AMX panels and remote or is better to use an iport?
Please note that this is our first AMX installation.
Thank you in advance for your advice.

You might be able to get away with less. The reason for one-per-AMX-panel is because they can only control one zone at a time, and otherwise there may be conflicts. If you can say without a doubt that two panels will never be used at the same time, they could share one. Perhaps not all of the AMX panels (like the R-4's) need to control the Niles. I just don't have an easy answer for your situation; I wouldn't have designed it that way in the first place, though I perfectly understand being stuck with something that changed along the way.
