4K,6K,8K Switch Mode PSU UPGRADE
« on: September 08, 2012, 10:47:43 PM »
Hello everybody,
good news for whoever is sick of his old PSU packing up, wants to power cycle the console at ease or simply save money on electricity bills...
I've just received an email from Norman Druce who (by kind permission) I am quoting here:

"The prototype will go into service in Nashville oct 10th, the details are being worked now, The unit will power a 72 desk without a change over, via 2 standard cables. I will try to post something soon, or feel free to say something on the forum. Thanks. N"

so we shall soon have more news!

Mattia.

My tech believes that switch mode supplies are quite problematic and actually prefer to be left on.

I have used switch mode for a while (even for serious loads) I think that if the system is designed well it will not have any problem.
the majority of things we use now days are switch mode, from computer to speakers to amplifiers to interfaces and so on..
your Adam S3As have a switch mode PSU (and class D amplifier designed by Bang and Holufsen inside), your digi 192 are switch mode...
beside a normal PSU has an efficency of around 20% while a GOOD switch mode can go up to 90% this means that you can save about 70% on energy bills..
I think it's worth waiting and see..

Cool, I'm REALLY curious about this. And the cost of course.

Stef.

PS Mattia, can't thank you enough for starting this place! Thanks!

Just received an email from Norman Druce, here is the front panel of his SMPS:



72 channels from 1 PSU...seems pretty good  ;)
I guess we'll have to wait for more news...

Very interesting!

I'm really curious about this. I'm also curious about the effects it has on the consoles sound.

Any more news? Got a price yet?

Stef.

not as yet...I am waiting for Norman to do the official statement.
apparently it's even quieter than the original SSL psu... so let's wait and see.
He told me the psu will be in service very soon and it will be beta tested.

Sweet.

Now if we could just get someone to write an emulator of the computer for a PC that would be awesome!

I spoke to someone here in Sydney, he was considering it years ago and said it could be done.

C'mon, we can play space invaders and pac man on a PC.. surely we can get the G auto and recall too?!?!  :-*

Hi everyone,

I worked with some guys up in New York a couple of years ago that were talking about building a Mac that would run the G Series Automation. Last time I heard from them, they dropped the idea because the time, money, and effort that would be put into development would be too much. There isn't enough consoles out there with owners who are willing to buy something like this to even break even with the production costs. And with Pro Tools, it doesn't seem like there is enough engineers out there that use the VCA Automation. I would love to see someone develop this, working on the G Computers is a pain.

The switching PSU's is an interesting idea. I am curious to how they will turn out and sound. I would be concerned about having noise issues. The 9000J uses switching supplies, along with about 600lbs of transformers for filtering and power conditioning. Hope it turns out well and is a success, Good Luck

Update? Dreaming of quite power supply and modern computer replacement (which is on the way as we know...)

received an email recently saying that the prototype is under test, so I am waiting to hear back from him.
I am going to drop him a line again!

Yes I had to completely redesign the unit since last time we talked, the good news is
we now have a working unit and all the modules are available in the states. I was
have problems with the Chinese manufacture and communication. the only difference
is these units have low noise fans that always run. During bench testing we had it
loaded with equivalent of a 56ch desk it barely got warm and was only drawing only about
7 amps @ 120vac! next week we will be testing it on a 4k, then it will go to nashville for critical
testing. if all goes smooth we will be able to ship units at the end of the month.
After critical testing I will be taking pre orders price will be $3200 it will have a
2 year warranty and be user serviceable and is will cut you energy bill by >50%. N
