Hi there,

So I bought a VSL1818 about a month and a half ago and was extremely satisfied with it. However this seems to be a feeling undergoing some changes lately.

First some background: I'm using my VSL as recording tool, however my primary use for it is for live purposes. The VSL is racked with three other units (a DI and a MIDI interface) allowing me to split the sounds in ableton live to different outputs. This way the PA has the freedom to adjust my music to the location it is played in. The fact that I'm real happy with the presonus software, preamps etc in my FS2626 made me go for presonus again and the features in the VSL convinced me to buy the VSL1818.

Though my VSL worked smoothly this Monday, having band rehearsal and a very very lengthy sound check at the radio studio, it give up for the first time during a very, very important live showcase on a national FM radio station in Belgium. Needless to say this was a big downer on my day/week/month.

Anyways, in the middle of the second song we played live, the audiobox lost sync. So I closed my DAW, plugged and unplugged, powered and unpowered my VSL and started over. Not 5 seconds later stuff hit the fan a second time. Therefore I rebooted my laptop and plugged, unplugged, powered, unpowered my VSL and started again. This time it held up for about 18 minutes. After these 18 minutes, you guessed it, it gave up again. End of our live showcase. fml

Now I wonder how this can happen? I've been testing my VSL1818 extensively today and found out that it doesn't work at all with one of my USB drives, eventhough it seemed to work in the past. Maybe it was that one I used for live (I know I used it during one of the fall outs, not sure about the others). Is it possible/normal my VSL1818 only works on one USB? Because the other USB's on my laptop are USB3.0 and, despite the new driver, my vsl1818 has never worked on these ports.

So at the moment I think I had this huge problem because my VSL might have been plugged into a USB it just doesn't want to work with. Why can this be? Any other possible reasons? Over-heating? Bad electricity? To many midi signals coming in through my midi interface (not my presonus though)? I'm pretty nervous about all this because I don't want to go to future gigs or on tour with something as volatile as my VSL has proven to be.

Please,
Help!

ps:
I use windows 8 on a 6 month old laptop on which all software is 100% legit

Could it be that the VSL1818 only works decently on the usb port you used during installation?

It still wouldn't explain everything. I'm pretty sure the first loss of sync happened while being plugged in in the "good" usb port...

I can't use my 1818 in a live situation either.

Luckily, I found that one out during rehearsal, not during a broadcast!

Have that happened, I would've played frisbee with my 1818!

Mine cuts out, at different intervals. I don't need to turn off the laptop, just the 1818, then turn back on, and it regains connection... for a while. Also, the sound coming out of it is what I would call ... "lo-fi". It's like listening to the radio on a bad receptor unit... sounds tiny and distorted.

I've tried all the workarounds, nothing sticks. I have no idea when I'll be able to use it as advertised.

What do you mean by "unlocking" the sample rate?

Open the software mixer window for the VSL, and go to setup, and you will see the sample rate, with a check box on the right.

Uncheck it and see if that helps.

On laptops all USB ports are not =... Some have conflicting ports or other things sharing the port... The 1818 is not a port specific devise however but if it's on the same bus with the drive that could be the problem.. as to why it worked fine then quit? have you turned off your auto update? The general rule of thumb is if it's working DON"T TOUCH IT!

You can go into the computer and run an IRQ report to see what else is on that buss...you should, if you haven't already, optimize your computer for Audio...these and many other procedures are documented in the Knowledge base.

edit...
make sure that there is plenty of hard disc space,and if you are recording to the boot drive that could be an issue as well...make SURE your computer is not going to sleep!

I don't see a check box on the Mac version to lock the sample rate.
Maybe it's something on the PC side.

My 1818 still sounds like Lo-Fi...
That's an expensive Lo-Fi unit...

Right now, its only duty is to act like a MIDI-2-USB interface... something that usually cost like $30...

Be sure you have you power options in windows set to custom and goes into power saving mode or hibernate. This is was happening to me which caused it to lose USB connection.

Hi there

I posted here a long time ago, but I thought I might give another reply.

Since last time I posted no drop outs ever happened. And I used my VSL1818 often. I played live shows, did rehearsals, did recordings etc.

But this weekend things went wrong again. During a concert another drop out occured, the first drop since my broadcast session months ago. The club where we played was steaming hot (two people even fainted), so I figured it might have been overheating. Therefor I asked the Technical Supervisors, after two drop outs in the first 30 min of our set, to supply us with a fan. After placing it in front of my flightcase (where my VSL is racked together with a DI and a midi-interface) there where no more drop outs and things went real smoothly.

Hence the question, is this normal? I mean, I think we now figured out the problem, but are there many records of this? Not just for the VSL but in general: artist dragging around flightcases and heat causing drop outs and issues and such? (mind you I felt the VSL and it wasn't that hot, it wasn't near my laptop, and there is still a lot of space between the VSL and the other compartments in the rack)

And is there an easy cheap solution that isn't dragging along a fan to every gig?
And in general: what is your opinion about this issue?

thanks!

I think that if people are literally fainting then it must have been really hot in there. I believe there is an actual processor in the vsl1818 (could be wrong don't own one myself) and that processor has a heat sink. The reason it has a heat sink is because processors generate a lot of heat, if it gets too hot, it will shut down, many of us have had this happen on all kinds of electronic equipment.

Make sure that if there are any openings or vent holes on your 1818, that you have plenty of space by them for air to get in, not having a built in fan it needs some space and in super duper hot environments it could need a fan blowing on it. . .

I'm planning on putting a rack in the back with 12v transfo's and 3 PC fans. Hopefully that'll fix things.
Anyone anny idea on what to pay attention to (I don't know if that could create hiss or mess up the power suply..)?

I hope this does not confuse things more but I wonder about a correlation.
I have had a FP 10 for years and the reverse happens with mine. When it is cold I turn it on and hear terrible break-up of signal that comes in way too hot (loud). It takes some warming up for the sound to correct itself. Also, there have been sound dropouts as well meaning all of the sudden there is no output. Turing the Presonus off and back on will always fix it but as you know there is little to save face when your sound goes out. This has been going on for years now and I just never did anything about it. I surmised that it has something to do with the internal routing. I make a point to NOT have a computer hooked up to it in a live situation for the very reason that I don't trust a computer for a whole show.
