    I put the voltmeter on the anti-thump connector and yup, I get 12v almost immediately after power up. Grrrrr.

    This time I fired up the utility that mini-box provides. It still shows 18v coming into the unit even tho I know it's 12. But I started playing with the other portion, where you can "Send Message" to the unit. You select a parameter and it shows what it is. If you want to change it, type in the new value and hit the "Send Message" button to update. This is, of course if you have the USB cable made up and connected. Amazingly enough there is a setting for anti-thump and the default is 3000 ms(3 seconds). I changed it to 15 seconds and "sent" it. It accepted the command. I then powered off.

    Guess what? It works.....well, sort of. It still puts out 12v a few seconds after the ignition on signal, drops to zero, then waits the 15 seconds and puts out 12v again. I don't know if the initial power on would cause any amplifier thumps or not. When you remove the ignition signal, the computer shuts off/hibernates, waits another 15 seconds and then kills the 12v to the amp. I don't think this is right because when Windows shuts down, it generates some thumps at power off.....while the amp is still on. Anyone else want to verify what I'm seeing? There are a whole bunch of other settings you can change, but most I'm currently not that interested in. The anti-thump setting affects both startup/shutdown. I'd like to see those broken out separately. When shutting down, I think I'd like the amp to die right away, long before Windows starts doing its thing.

    Maybe 1.2 or later versions can resolve these anomalies. I'll try to fiddle more later in the week and see what kind of results I get.

    I've been wanting to take a voltmeter to mine, but I've been too busy. I'll try and do some testing tonight...it's looking like mine isn't faulty after all, rather they all are. >.<

    I've done some testing with mine now, I have about the same results as you, jimmler. Even though I told the utility to change the anti-thump delay to 10sec, the amps came on at about 16sec, so you may want to try changing your timing to something else to see if it's actually working or you just happened to pick the number that the supply always uses.

    Here's my startup breakdown

    Ign on - 0

    Amps on - 3

    Computer on - 5 Thump

    Amps off - 7

    Amps on - 16

    It just occurred to me that may not be 100% true, the "amps on/off" is actually the sense signal on/off, the amps may stay on the whole time, i'm not sure if they've got they hold themselves in the on position for a set amount of time after receiving a signal, I'll have to check that.

    Well, we've verified on our respective units that it's not working as advertised. How do we get mini-box to do anything about it? As mentioned in other posts, their tech support has been completely unresponsive as far as any of MY requests have been concerned. I'm getting really tired of being a beta tester.

    I'll try sending them a few e-mails, but I doubt I'll get a response either. The problems are disappointing, but not enough to make me go through the hassle of an rma and getting a different supply.

    I hope they fix this as i'm looking at buying 1 to replace my M2,i don't use the amp remote function so i'm not too worried about that,just need it to work correctly as a psu.

    Does it?

    It seems to be "luck of the draw."

    I bought one, and have been testing and using it.

    It took about a dozen starts (power-on, disconnect power completely, repeat) before it actually worked, and the timing functions took quite a few more.
    Since then, it seems to work properly 98% of the time.
    The other 2% it either won't start or won't shut down.

    Some good news. I got a email from Turos Laszlo. So I set the amp thump to 30000...which is 30sec...by this time i'm in windows then the amps turns on. But I still get the thump when windows shutdown. They need to make a setting for windows shutdown. This is my only problem with the M4. Befor I got this new (Intel D201GLY2A) I had a ITX MB and use this app call (Volume_Amp_Control) on the com port...but if I hookup the com port and have the Volume_Amp_Control load...The Intel D201GLY2A reboots. This is why i'm using the amp thump on the M4.


    Soloxp)
    The problem is every time I boot or shutdown the pc...I get this loud thump sound. I try using jumper J8 pin 8 and jumper J6 the inside pin. The wire harness that I got from you guys...when you sent me this M4-ATX PS. How do I connect it to my amps remote? If I just need 1 wire...then I already have that done. Is there a way to delay the time on the amp thump so it does not start to after windows boot?


    Turos)

    There is a parameter in M4ATX utility software called "THUMP Timeout" which is now 3 sec default value.
    You can download the software from the website.
    Try to adjust this value to a higher value which you need.
    For this you have to make an USB connection with the M4.
    Follow the steps described in the manual.
