Hi there

I've tried to connect my Focusrite ISA 220 digital card to my Pulsar I plus from late 90's. Tried the ABU/EBU first, didn't work. Then I tried the optical out, and then I got connection to the sound card but only for 1 second at a time, followed by 2-3 seconds where it didn't work, the 44.1 blinks and the cursor shows its "I'm working" signal. Then 1 second again, followed by... So it's real unstabile. Afterwards I tried, again, the AES/EBU and this behaved the same way, until after 1 minute or so when it returned to "not working" condition again. Very strange. Like the optical cable awoke the digital out board, but only for a short time and still unstabile. Must be my soundcard then? Or what do you think. I heard that some old cards may have this problem. What can I do about it? Shall I have a new soundcard to exploit the digiout?

Regards

Hope to hear from you

you have to set the Focusrite as clockmaster and the Pulsar to slave to it.
With optical cables you HAVE TO use Adat 1 on the Pulsar (whichever that is...), the other one doesn't work with optical spdif

in this setup the Focusrite has to be always on, otherwise Pulsar will not output any sound due the missing master clock.
The master/slave settings are saved with the project, so it might be useful to have 2 versions, if that unit isn't constantly on (to avoid manual clock switching)

cheers, Tom

Hi! I did all this already. Focusrite is the master, optical was via adat1. Still the computer/preamp reacted as I've described.

which software version are you running ?

I also have a Pulsar One and I remember in one of the older releases there was a small patch file to solve digital IO problems.
It definetely worked in my case, but I cannot remember the version (I have the file archived though).
I'm not sure if it's required from SFP 3.1c onward, which I've installed a couple of times since then without the patch, but I don't use optical spdif anyway.

do you have a CD player that you can use as a temporary source to check the digital IO ?
I assume you ruled out cables or a dirty connector already. Compressed air should help against dust.

cheers, Tom

as Astro said try first a very simple setup by sending a dig signal into the card from an external CD rom/DVD or whatever.

if you get a signal into your SFP mixer then you have to look at your setup.

also make sure you have one of these software SFP 3.1C or Scope 4.0

this has nothing to do with early revision boards. I have Pulsar 1 and the Dig in works just fine.

early versions of 3.x has a spdif patch.

I'm so happy for your time. Thank you so much.

I have only version 3 of Pulsar. Should it be included here, the patchfile for the digital I/O's. Otherwise I would very much like a copy of the file. Of course I will try with other digital sources, why haven't I thought of that before. Cables are new and should be working quite fine.
Thanks

I've uploaded the file into the <a href=http://www.planetz.com/forums/viewtopic ... =0>presets and tools section</a>

cheers, Tom

Thanks Tom. But the file is a destination patch. I have no digiout from the computer, it's the digital in that is wrong. I already have a SPDIF source patch, but the one you sent me looks different. If you have a source SPDIF as well, I will gladly have it. And a little question: It must be connected exactly like the normal analog source, right?Straight into the usual channels on the mixer (Big Mixer V2 I normally use).

Thanks

the solution to your problem (in case this applies) is in the PulsarConfig.pep, at least that's how I interpret the readme.txt.
You may connect the module with whatever (audio) connectors you like, there is no fixed rule. But of course it makes sense to connect it to a mixer channel.

cheers, tom

Tom, it is incredible. I just replaced the bugfixing file with the old one and WHOOPS - digital connection. Thank you VERY VERY much. And I even believe I can tell the difference. Now I can (finally) make some music.
