So, mine seems to not be starting with sound at all.

Presonus say it is a hardware issue and that i should take the mixer to get fixed......in London, 400 miles away :(

Hi everybody!
I have been using my 16.0.2 for almost 5 years now, take it out to the outside world 3-4 times/year, it works as a stand-alone most of the time, very rarely do I connect it to my MacBook. Power comes from a UPS (which also powers everything else in my living-room-studio, keyboards, drum machines, amps, rack stuff etc). The board and the rest of the equipment stay powered 24/7 (except the exceptional exception), because I would have to switch on and of half a dozen times per day, which isn't that good for PSUs and other electronics.

Yesterday night, I switched on the phantom power to a pair of mics, I noticed some disturbing hum. Unplugging, replugging the mics, switching phantom on and off didn't change a thing (well, with phantom off, I didn't have the hum anymore, of course)
I decided to switch off the mixer, waited for 5 minutes, powered up again... And no output whatsoever (I use phones and monitor out as a general rule, my little PA is barely used). I could see input signals and output levels, but no sound from phones, monitor or main. I also noticed the two last strips (13/14 and 15/16) were unresponsive. I connected the Mac, performed a factory reset, to no avail. I also switched from 48 to 44.1 and back a few times, no change.
Considering the hum, I suspected a power supply issue, so I opened the mixer and checked the PSU for obvious damage. The only thing I found was capacitor C47 (3300mF/10V) with a slightly bulging top. I measured all the voltages (no other boards connected), they seem OK. With the other circuits (except the ones in the to half of the mixer) connected, the heatsink with the Voltage regulators was quite hot. I will replace that capacitor on monday.
Is there something I should investigate further? No output at all (no computer involved), and two dead inputs (strips 11 and 12), plus a humming Phantom.
Thanks for your reply
Regards

Michel

Almost 50,000 hours? Amazing, that your 16.0.2 made it. Give it a repair or replace it. There is a USB version available and many other mixers from PreSonus. It's time for a change...

4.5 years @ 8.760hrs/yr, that's around 39.000 hrs. Some 11.000 to go, then.

Seriously, I'm quite happy with this board. It's the first time it has let me down, and it seems to be a PSU problem.
I found a broken wire on a connector to the converter board, I will replace the connector tomorrow. These things cost less than a euro, just like the capacitor. Worth a try.
If this doesn't work, I will send it to a repair centre, get a quotation and decide. It's wrong to replace equipment that satisfies my needs. If I were to replace it, I think I would go for a larger model, 24 inputs or more. But the 12 strips are adequate for my current use, and I can't afford to spend 2.000+ euro for the moment.

Did you repair the wire or capacitor? Did you solve the problem?

I did replace the capacitor and hardwired the cable (couldn't find the connector, 7 poles at 1/20"). But this didn't solve the problem. The board powers up, but stalls at "waiting". Possibly my soldering work wasn't well done, my eyesight isn't what it used to be.
I will reopen the mixer or I might have it repaired at some point, I'm a little short on cash now.
I did buy a 24.4.2 in mint condition, paid 900 euro including an unused flight case.

“Waiting” means that it awaits the dsp to boot up. Check the connections to the dsp pcb. If your flash memory is worn out you’ll get the same condition since it then can’t download the dsp code.

After such problem, which could occur on live perfomance, you bought Presonus products again???

Any electronic (or other) device will eventually break down. This can happen at any time. I have used lots of other equipment (audio and other), and it has happened. So what?
Would you never buy a brand of car again because yours broke down?

The "best" equipment is not a guarantee for 100% reliability. Note that devices will only break down when you use them. This mixer has been used in my home studio, hardly ever on other locations, power was almost permanently on, meaning it ran for approximately 40.000 hours. That's quite reliable, I would say.

Thanks for this very useful information. When I will have the time to reopen the board, I will investigate this. Or I will have someone do it for me ;)

I meant that problem with sound out is seen on much mixers. And I will see if they repair it for free. Because it is known problem... Also, I'm from Russian Federation, I'm not sure I could get reliable service and mostly not reasonable price...
As for me I used it on one live show and it disturbes me from the first show!

From what I've read the. 5v resistors go bad. I just started messing with my 16.0 2 today.channels 1-12 are not working. Ipluged itin and they work. I then updated firmware and once board turned of and back on they didnot work. I'm confused and pissed off as presonus is real slow returning my email messages. All i needro know is what their bench fee is to fix my board. :thumbdown:
