Quick question – How do I set the brklyn module to 96k sample rate?

I set DVS to 96k, did a factory reset from the controller, but still only gives me the 48k option on the card in the GLD after they resync.

The iLive is 48K and the Dante card is also fixed 48k. Even if you could change it you would only be resampling (upsampling) the 48k iLive signal so there will be no quality advantage.

Thanks, the issue I have is a lot (every second or so) of clicking when I run 48k on both sides (sounds like re sampling errors, or a clock problem). No routers, cable directly connected to computer. Clock is locked with desk preferred master… DAW is Reaper.

any ideas?

Carl.

I’ve had the same issue before, it’s a sync issue.

Make sure that in Dante Controller under device view that the brklyn module is set as slave to external word clock.

(Hopefully I have that the right way round - I’m not in front of the console at the moment, but either way try changing that value!!)

Also, the Brooklyn module in the A&H should be set as the only ‘Preferred Master’

please do not adjust your set; normal service will be resumed as soon as possible!

Thanks, I had set preferred master, but not external world clock. I will try that.

Preferred master works. thx.

I still get some ‘static’ on playback or it sounds like the Dante card is clipping, with no clipping on the desk – is that possible… will poke around some more.

It’s a clock issue. Double check in your dante controller software that its preferred master (which you’ve done) and that the sync to external clock box is checked too. It needs to get its clock from the desk. Also your desk should get its clock from internal not port B.

[:smiley: ] good luck

Maybe a little off topic, but what if you have a GLD connected to iLive as a MON desk.

Just to confim, should the GLD clock in the mixer be set to internal or Option card?

I have used that kind of set once, and I set GLD clock sync via option card and that works great.

GLD + AR2412 + Dante

Got a tip to use a 1G card and not a 100M card. that seems to have resolved the last issues. Will run a more extensive test this weekend.

Great Discussion and more Dante/GLD Issues:

Setup is MacBook Pro, Dante Controller and Virtual Soundcard, Reaper 64 and 32 bit versions (makes no difference to the problem). Cisco switch with Qos services (problem below makes no difference whether I use the switch or not).

I want to multitrack record and also monitor the recording now and then by using the monitor capability of each track in Reaper.

I set up an aggregate audio device that has the Dante Virtual Soundcard and the Mac line out.

All of this works SORTA:

I also found through experimentation that the preferred master and external clock settings as mentioned before eliminates the random clicking issue.

However, when I listen to the sound of a track, at times it slowly starts distorting over time and eventually goes completely silent. Then it comes back. Now this sounds like another clock issue.

My plan is to not aggregate the Dante and line out and route the monitor output back into the GLD on an unused track. Of course while recording I will be interrupting the live audio guy a bit. But it will help determine where the problem is. If that works, I may try a different audio device for monitoring. I have an MBox2 available.

One other interesting note: when you unplug the headphones from the line out jack on the Mac, all sound is list for several seconds. The Mac must be re-configuring itself as it senses the change. I got around that with the use of a short 1/8" extension cable.

Any other ideas?

My issues are not yet solved with Dante.

Clicking is fixed. Still have static randomly on all channels. Swapped to 1G card, was better for single channel test, however with full recording this weekend the recording had random static on all channels – unusable…

Checked, no clipping, levels are all good.

Any ideas / anyone seen this before?

Carl.

Try to increase latency settings for DVS and also buffer size in DAW.

More Info:

  1. Eliminated the “aggregate” recording device on the Mac and just recorded with Reaper the Dante Virtual Soundcard. This solved the clocking issue.

  2. Eliminated trying to record to a USB flash drive - used hard drives instead. This solved a “reaper hanging/crashing” issue.

  3. Recording was (as far as I see now) rock solid EXCEPT for one ominous “click” about 1 hour and 47 minutes into the recording. I have not investigated the “source track yet” to try to determine the cause. BUT it was about the same time the GLD80 surface “froze” for about 3 seconds (no loss of audio) and shortly thereafter most channels clip lights blinked (again, nothing that could be heard audio wise during the live event).

  4. We still get Qos warnings on the dSnake every 3-8 minutes? Does anyone else have this issue???

The live event went great. The one click/peak issue we need to try to find the cause. The Qos errors on the dSnake troubles us. We are using the A&H snake! We feel that we shouldn’t have ANY errors under normal circumstances.

Thanks,

I only have Reaper running, killed everything else off. I’ve also gone up to 6ms. I have no USB recording going on the desk, and am streaming to disk. What is your buffer setting in the Reaper? What latency setting are you using?

I get the static every few seconds, no clicking that would indicate a clock issue.

Hi Gents,

Running Dante with reaper for a while.

Reaper 64Bit is trouble with DVS and RME Madiface (Use 32Bit version!).

Dante is a 1Gb network system so always use 1Gb units in a Dante network.

Make sure you are using at least CAT5e cables!

In Dante controller Tick preffered master and Sync to internal and the Dante card (a Dante Hardware device (so not the laptop) needs to be clock master of the Dante network, The Dante network should sync to the GLD/Ilive).

In Reaper just used the standard settings (Also in DVS).

Set audio card to ASIO en set I/O channels.

If you have an 7200 rpm internal HDD you can easily record 48 channels to the internal HDD.

If you have an 5400rpm HDD 25 channels is the limit.

If you have “static” ticks something in your network is not ok.

Try to do 1-1 connection without switches.

Some Network cards cause failures wich result in Ticks&Clicks.

If you are using to set up a dual desk system:

Set the GLD/Ilive that controls the gains (so has the I/O racks connected) to Prefered master& Sync to internal.

The 2nd console should have no ticks checked.

On the GLD external Sync menu Set sync to " Sync to port B" (instead of “internal”)

Route you audio on the network (if you want to do virtual soundcheck set DVS sends to Multicast!)

In some rare cases routing or Ip Adressing gives some errors.

Just reset the Dante cards to factory and reroute the channels.

All should work fine now!

Success this week…

Our dealer swapped the Dante card with another one after not being able to get it to not have static. After swapping the Dante card in the desk it worked first time. Funny part is we then swapped them back, the original also now worked. Almost as if swapping the card caused the desk to re-sync.

Anyway, it works now and no tips to add to the thread.

thanks to all that posted on the thread. First clean recording.

Carl.
