I ran a show w/several bands at a small club yesterday using the SL 16.4.2. The board locked up several times and I had to restart in order to use it. It did make it through the show...however, it was very annoying. This has never happened before w/this board. Some observations:

1) 1st time I used SL Remote on an IPad for remote mixing. Once I disconnected the Firewire (Macbook Pro) from the SL, things seemed to work better. (I've previously used only the Macbook/Firewire and Capture and never had an issue)
2) The room was packed and warm (compared to other gigs).
3) I've had the unit since Feb. 2011 and never had a single lockup.
4) When it did lock up, some of the channels might have been clipping.

Any advice?

thanks.

So, maybe if I ask this a different way.

The SL board never locked up w/Macbook Pro running Capture via firewire.

When we used the SL Remote on the IPad, it's locking up. What in the IPad or Router (Netgear N-600) would cause the board to start locking up?

thanks.

The only difference between the two is that you have wireless running. I've never known wireless to lock up a StudioLive, though. I'm not 100% certain that it is the culprit.

Do you have a support ticket in with Presonus yet?

I'm not a mac user so I really can't steer you beyond this. I hope you get what you need though.

I talked w/Presonus support yesterday evening. They had never heard of the SL Remote causing this issue. However, they had no ideas other than could I reproduce the problem.

Without the full band running, how would you excercise all inputs and mix to try to reproduce the problem?

I do have a capture session (recording) I could run from the MacBook Pro...and try to use the SL Remote at the same time. Not sure if this would reproduce the issue...

I did note that on the iPad, I did not have the "Timeout" set to "Never". Also, I had not updated the Router firmware (NetGear N600) that I was running on the 5GHZ side.

It did not seem to occur w/o the Firewire, Router, and iPad connected. However, I was not actively mixing on the SL 16.4.2 (we run sound from the stage and I'm also a guitar player in the band). So, basically, when the board is just processing mic/direct inputs the issue does not occur. It only seemed to happen when I was actively mixing...and/or possibly a clip/overload situation...

Thanks for the input.

The router firmware shouldn't make a difference. And it also eliminates (for the moment) one possible solution.

Is this on a PC or a Mac?

The only thing that comes to mind in this instance is possibly a bad cable or port on either the Mac or the device. At least as far as things you can check yourself.

It could be something internal. Have you tried force flashing the firmware? It could be a faulty firmware install.

Thanks Mono. I've ordered a different, more expensive Firewire Cable (recommended on another thread).

If you have another known working cable for the moment you could try using it to verify. At least til the new one gets here.

New cable should be here by our next show (Friday)...

Also, I should throw in the venue we were playing in had a lot of RFI going on (the guitars were buzzing really bad...had to gate them). So, the Firewire cable I ordered has ferrite magnets on both ends...maybe this will help.

To simulate many analog inputs - Connect an audio source to ch1. Patch from ch1 direct out to ch2 line-in. Continue this way for all channels.

Nice trick

Not sure if this does the same thing, but I simply ran capture (previous recording of the band) back in w/the Firewire inputs on each channel. Then tested mixing w/the iPad. So, far, I have not been able to make it fail again.

So, the question is, can RFI disrupt the Firewire signal can create issues (when it failed, the club we were playing had a lot of RFI interference).

No, not the same thing...

The preamps draw more power depending on the input signal so if there is anything bad in the preamps then the firewire test won't stress the board.

Since there is two stages of preamps (mic --> line --> buffer --> a/d) then given my example above you should use direct out into xlr instead to maximize power consumption.

Also during the live gig you probably had some phantom powered mics and/or DI's connected that would consume additional power.

However do this only if you intend to stress test the mixer....

The ferrites on the cable is only to reduce/eliminate RFI FROM the cable - Not into it.

Firewire uses shielded cables and the signals are tranfered in a balanced manor + using twisted pairs so rfi shouldn't plav havoc on a normal firewire cable.

Perhaps the mains power was bad. Or it could be the voltage ripple on the gnd between the mixer and the mac was to high due to faultu grounding and therefor interfered.....

Great to know. Thanks.

I have a show at the same play tomorrow night. Hopefully the rig will hold. I've used the same Macbook Pro/Firewire setup before w/Capture to record shows. Never had a problem. However, this time there were 2 additional factors: 1) 150+ Bikers in a small place and 2) the iPad/SL Remote... So, I'm not sure why it looked up this time, unless there were additional power draws. I do have the rig plugged into an inexpensive computer voltage regulator. It has never caused an issue...

Once we get through the show, I will use your recommendation and try to stress it. Thanks.
