control input on a relay is a high impedance input, perfect for the trigger functionalityThe 12v trigger from my Denon 4400 is on all the time, as it opens a relay allowing 240v to my inline fans.

The 12v trigger form the PJ ?
Agreed. Not sure I'd trust running the cheap fet they use as a driver at half it's rated current for any extended length of time . It might be capable of 100ma peak but sustained? Relay a better option.JVC trigger out is 12V DC and 100mA. Could drive a couple of Noctua fans wired in parallel in theory as only 0.025A each but not really designed for this.
Better used connected to a trigger relay switch or alternatively downrate the fans by running them at 5V from the USB service connector (presume 500mA).
Yup, similar to what I linked to above, you need to turn it on/off though so one of those multi socket adapters where one of the sockets turns on/off the other when used would workCould you use something like this 12v power supply connected to the fan molex connector?

Mark you should brand and sell these as PJ noise solution boxes!@Triggaaar does this help?
Notice the fan fitted? Although after testing last night I don’t think it’s needed at all.

Yes, thank you Simple and effective.@Triggaaar does this help?
Well I like the way the foam on the front is in the direction the air wants to go, which may make the air move more easily. It's not on the top and bottom, but it's obviously working well enough.Notice the fan fitted? Although after testing last night I don’t think it’s needed at all.
This is very similar to what I’ve done, I’ve just added some steroids to the mixMy Z1 came with these clip on diverters, made quite a difference.
Do they do something similar for the NX9?
Same lensIs there no limit to your ingenuity Mark
I hope you’ve made it big enough for the NZ9 to fit in and be adequately cooled and silenced ready for the next bout of upgraditis
Oo that's good to see, they're basically saying that what we (well, Mark so far) are doing is sensibleMy Z1 came with these clip on diverters, made quite a difference.

Yes, in the case of these plastic ones it just changes the direction of the exhaust, reducing the noise heard.Oo that's good to see, they're basically saying that what we (well, Mark so far) are doing is sensible
@Topmetom 2 Not sure who's worse, @mb3195 for producing the video ( talk about niche ) or us for watching... I'm guessing the latter !Not a bad idea though tbh! Nice little sideline…hehe
Yeah I’d thought I’d taken a photo of it, but turns out it was a video. Suppose I could have screen shot the video and posted as a picture.@Topmetom 2 Not sure who's worse, @mb3195 for producing the video ( talk about niche ) or us for watching... I'm guessing the latter !
Question is, has @The Dreamer now budgeting for a trinnov?
Not yet. The major difference I heard was that Mark's Top Front Atmos were quite a bit more noticeable than mine.
I know the positioning of mine are compromised somewhat, in that they are set too far into the recess in the ceiling, and they are pointing straight down, rather than being angled towards MLP, or the seating in general. Indeed Audyssey has, on occasion, told me there's a problem with the Top Fronts when calibrating - the microphone simply isn't getting a line of sight to them, and the Volts apparently are a little limited off-axis.
The original plan was to have them angled by mounting them on a sloped bracket - but in the end I CBA'd to build them and just screwed straight through the back of the speaker cabinet into the ceiling. I think I'm going to revisit that decision. Same goes for my rear Atmos!
Sound aside, the major things I noticed in Mark's room vs mine, was firstly the all-encompassing blackness. And having got the Sony up and running last night, I can see why - in comparison to my Epson, this thing's a light cannon!
Admittedly, I've always run the Epson in 'Eco', low lamp, mode, and I've yet to do a side by side comparison (just waiting on an HDMI extension lead so I can go back and forth from one to the other - I'm not getting rid of the Sony - I just want to do this so I can write up a fair comparison)!
But the brightness of the Sony's image means that the reflection from the screen lights up a lot more of the room than the Epson ever did. I already have some black Camira fabric on order, so the first two panels closest to the screen on either side will be changed. And I also have some self adhesive velvet flock arriving tomorrow to cover the first bit of my 'dropped' ceiling. Without it, the lighting up of the front portion of the room is a little distracting. I totally get why Mark has gone 'all black'!
And then there was the Quake attached to the seats. It certainly adds something, but not sure if it's for me. It's been incorporated really well, and Mark said he had gone to a lot of trouble getting the timing and cut-off just right - certainly watching the demo clip of Fury was great fun. I'm going to have to watch that again on my system to see what I'm missing - but I think my twin 18's move enough air themselves to make the room shake, and I've yet to build and install the subs for the rear of the room (still on the to-do list). But it's nice to know that even after I've filled the room with subs, there are still things to play with.
My next major project is to play with JRiver, and see what I can do with that and MADVR (or possibly JRivers own video processing, which is being actively developed).
I can see Mark struggling to find 'upgrades' for his room going forward - it's about as 'reference' as it could be. Maybe the NZ9? But honestly, having spent an hour or so in there, I'm struggling to see how it could be improved (and we were watching the Sony)!
If he wants something to do, moving forwards, I'd suggest extending the 'Shed' and sticking another row of seating in there! Then he'd have an excuse for a Trinnov 32 and more speakers! He knows where to find me, if he ever lets go of his current processor!
