Make sure the source on the channels is set to analog, and not digital.

The console was turned off for a few hours.
I turned it on and the channels are back to normal.

Good to keep in mind... but a kind of a "windows" solution.

They are little computers essentially. Reboot isn't just for modems.

Good luck.

I agree of course.
Facts is I did several on/off. I even unplug and turn on to be sure no more juice in the circuits.

Seems more time than 1 to 30 helped.
Thanks to share those terrible moments with me.

The story is not over.

I'm using the mixer 4 times the week and it happen that only 2 channel (13/14 and 15/16) only work.
Not only with RCA input but also XLR input (Microphone).

I take care to turn on the main power switch, then last of everything the console, but still...
This evening I can't use it.

Does anyone have a suggestion ?

Is this with a computer connected to the mixer? Sounds to me like a Tech ticket is in order they will get you up and running again!

Hello,

No computer is connected.
I wonder what is the difference between channel 1 to 12 and 13 to 16...

May be some pros can help me with a few question related to my issue.

I'm trying to figure the difference between channel 1 to 12 and 13 to 16.
I understand there is in the console a 12 input class A XMAX microphone preamp.
Is it assigned on input 1 to 12 ?

I also checked the Block Diagram of the console and re-tested using XLR input, TRS left and TRS right and it is the same.

Input meters are not moving when the problem occurs so the issue seems to be from the XLR/TRS input to the A/D Input Buffer. (Studiolive 16.0.2 Block Diagram)

Seems like a hardware problem.

keymcgee, thanks for your reply.

I bought my device in the US and now I'm in a different country (Israel) and it seems it is a kind of complicate to apply the international warranty and I'm trying to figure how we can solve this with Presonus.

I'm confident a solution will be found, but in the meantime, do you have any details about the problem you had and the solution that was applied ?

What was the technical issue ? Is part has being changed ? What did they told you ?

It will certainly help me to progress with Presonus if we have a precise idea of my issue.
It may also be important for Presonus to fix this issue if it is not an isolated case.

Many thanks for helping me with this.

Bernard

Yes, You need to contact Tech support and they will get you back up and going again.

Cheers

Same exact thing happen to my 1602. Only last 2 channels worked. Had to send it in to be serviced.

It took a bit of time before I get my StudioLive back into his place but...

Hopefully, Presonus team took the time to understand the issue and helped to get it sorted for the same price I would have paid in US.
I got even a little bonus with accessories.

Happy Presonus Customer.

Same thing with my 16.0.2
I turned it on, only ch 13-16 works.
Have not done anything since I last used it
and then every channel worked.

It doesn't look like a factory reset can help, so get the board repaired in your service center. You will have to describe what the problem is. They will respond to it. Luthman Scandinavia KB in Hägersten is your distributor and probably also takes care for repairs.

Good day;

I'm repairing a studiolive 16.0.2 mixer with precisely the same fault, when turning it on it works fine, but when you turn it off and turn it on again they stop sounding channels 1 to 12, they only work 13/14 and 15/16, I would like to know how have solved, for what I see is a common and recurring failure in these mixers so it must have a simple solution (maybe some factory defect) , the analog inputs work with the DAC PCM4204, all the reset inputs of the DAC (pin 10) they go in parallel so I do not think that's the problem, since I update the firmware and the problem continues, if I connect the mixer by firewire to universal control and I select channel 1 as a digital input if it gives sound, so the fault is DAC back, tomorrow I will review with oscilloscope to see if the analogous signal reaches to reach the DAC input, if so I imagine that the failure will be the DAC .... the three DAC at the same time !!!. .. Any suggestions?

...

Mine was repaired and worked fine for about a year.
One day they were a power outage while the mixer was on and since then problem is partially back.

If I plug the mixer to the computer it loss all output.

I have to physically unplug the mixer, plug the computer (MBP OSX), wait for about 3mn, plug back and turn it on.

One thing I noticed, if I hear weird noise from the monitor (kind of "tack, tack, tack...") I know it will be ok.
If there is no sound I just redo the all operation.

Once working, it work for good.

Well I tell you that I could solve the problem of the mixer.

The damage was in the 5V regulator that feeds the first 3 ADC and therefore stopped working the first 12 channels, the 5V did not reach the measurement point, only 3.3V arrived, the other regulator fed the output DACs and the ADC of the input channels 13/14 and 15/16.

The two regulators are on the left side of the main board, next to the connector of the power supply.
