Here are some things you can check:
1. Check if the right NIC is being used.(If you have multiple network adapters)
Go to Common > Network Information and check the mac address to see if BA has selected the right nic. If not disable the selected NIC until it selects the right one. I haven't found a way to configure the nic it should use.
2. Check your network setup.
Livewire uses multicast, is your network configured to use multicast? If both devices are in the same broadcast domain(they have the same or no default gateway) network it's pretty straight forward and should just work. If however the devices are in different networks(they have a different default gateway) then you have make sure the network is setup for multicast routing.
3. Setup the source(studio):
Go to HD Processor(or watever the core is you use) > Misc > Livewire > Main Output
Choose a channel number, is used 1. And click enable
4. Setup the receiver(transmit site)
Go to Passthorugh(or watever the core is you use) > Misc > Livewire > Input
Choose the same channel you set at the source and it should start streaming.What kind of device did you connect to the spdif in? Is it capable of doing 192khz sample rate? Because if you use BBPASIO for generating mpx it will run in 192khz and in that case the input also has to run at that sample rate.

Unfortunately Musikhaus Korn doesn’t ship outside of Germany..
That’s not true, they did ship me two cards to the Netherlands. Did you ask them if they wan’t to ship to the US?
The card can be bought here for only €139,- incl. vat:
http://en.musikhaus-korn.de/Marian-Trac … 59742.aspx
I bought two of them over there, I don’t know how much the shipping to the US will cost but you should be able to stay below $279 total.
The website is mostly in German, but if I was you I would contact them by mail, and ask about shipping to the US.
info at musikhaus-korn.deOr just wait a couple of months for Greece to go bankrupt and get an even better dollar/euro exchange rate…🙂
Good luck!

Buffer size is not a big issue for me, but SFN over internet scares me a bit…
Anyway, it will be a very interesting experiment. 🙂[/quote]A very interesting experiment indeed, when I was discussing with Leif how we might like a Digital MPX STL to work (this seems like ages ago..), I did conceed the point that MPX over the internet might be a little optimistic but I’m certainly hoping to be able to use it over LAN and WLAN networks such as 5.8Ghz TCP/IP links. This now will be all the more of a sweet idea if an SFN will work over this too although I guess some extra functionality/compatability may have to be included in any future IP/STL to allow the extra SFN info to be passed.
Fun times ahead I can predict.[/quote]I don’t see problems, over here in the Netherlands it’s fast and stable enough. I’ve used the internet for regulair l/r streaming stl’s a couple of times.
One time 4 days in a row without any skipping.
When it comes to bandwith, only the studio-side needs a big upload-speed. I currently have 5 mbps up at home, and that’s not an exeption over here. And internet is getting even faster. In the summer my upload goes up to 10 mbps…
You just gotta make sure you use a large buffer, and yes… that causes a large delay… But who cares?The serial port could be used to read the status of the SFN adaptar, to see how close it comes to running out of audio in case of a internetstream for example.
Using this together with Leif’s idea of streaming mpx at 128khz 12bit using Flac(Which will result in a bitrate somewhere between 1.1 and 1.3mbit) could make it able to use the internet to create a SFN! Make sure you add quite some memory to the SFN adaptar, so that it can create a large buffer.
And for the delay, 100ms is already to much to monitor of air. So if you can’t monitor of air, what’s the difference between 100ms and 3s? The listener won’t notice:)[quote author=”sigmacom”][quote author=”Diekgait”]Sounds very interesting! Can you please explain the idea a bit more. Wil it be a combination of tcp-ip to connect the boxes and gps for sync?[/quote]
There must be phase, frequency and modulation syncronization of all RF carriers that constitute the SFN.
I need AES/EBU, no matter if it’s over IP or any other media! At the moment I don’t know if the boxes will have IP interface by default.
Synchronization will be based on GPS receivers and will follow the basic concept of ETSI TS 101 191 specs.
I am dying to describe in detail how it will work, but I don’t think it is wise to reveal this… 🙄[/quote]We’ll maybe a serial interface will do, because you can use a pc to feed the digitall mpx anyway. So that pc can control the box using rs232/usb as well. I hope Leif can find time to write the ip-stl software, this will be so damn interesting to fieldtest!
[quote author=”sigmacom”][quote author=”Diekgait”]Stelios, are you going to implement GPS for cariersync and maybe digitall mpx delay?
Dennis[/quote]
Hi Dennis,
Not for these 5 prototypes, but yes, there is plan for SFN support.
There will be a separate box (SFN Adapter) at each DDS exciter, plus one SFN Controller at the studio.
The concept is based on DVB-T standards and it is viable only with digital audio or D-MPX.[/quote]

Another hint for Intel Core2 and CoreI7 users:
DISABLE intel speedstep in the BIOS! I tried lot’s of things before I found out what was screwing up my sound after a couple of seconds all the time.
Dennis
I can’t wait to try this thing!
I have a Asus Xonar D2X and I’ve always regretted the purchase of it(bad drivers, no low latency possible) but it does support 192k optical spdif out:)Do you have any idea when it will be available, and how much it will cost?
Dennis
It’s very simple, if you have any problems make sure you run the latest version before you start asking questions.
Leif has fixed many bugs in the latest releases.
@Damber:
If you don’t want the stereo enhancer just disable it.For streaming MPX you would need 1mbit/s+ which you can’t get with a regular dsl line, at least not the upload. So in most cases you wouldn’t be able to use it.
The only thing you can do with this version is: create a batch file that kills BA, replaces the ini file, and then starts BA again.
You could shedule this batch file to run at 4 am or something. It will give you a few seconds of silence, but it will work.
Don’t want the silence? Wait for the hardware version:)
