Topic: MADIFace USB - Four unresponsive channels

Hello,

I'm shaking out an upgrade to a MADI-based setup. 8 channel AD card connected via optical to MADIFace unit.

Of the 8 channels, 25 to 28 are receiving a signal from the card fine, channels 29 to 32 are unresponsive (or at least not offering indications of receiving a signal).

Preamps and desk are fine, cabling is new. The DA card is indicating signal for all 8 channels.

My guess is I have got some setting wrong with the sample rate settings, since it is precisely four channels that are out of action. I am running at 96kHz and the clocking is reporting ok.

I have read the manual thoroughly but must be missing something, any ideas appreciated!

with thanks.

Re: MADIFace USB - Four unresponsive channels

You could do a test, switch everything to 48kHz
What product is this AD card ?

Thanks for getting back to me so quick.

I did try the 48khz test, the final responsive channel drops down to 14, but otherwise the same situation.

The card is a Burl BAD8, as I mentioned the signal lights (both signal green and red overload) are responding (for what that is worth).

with thanks,

Re: MADIFace USB - Four unresponsive channels

Now it's even more unclear what is going on.
In Totalmix do some signal arrive from the BAD8 ? On wich input channels are these signals visible ?
Wich of the 8 channels from BAD8 are missing ?

Re: MADIFace USB - Four unresponsive channels

Sorry I hope I'm explaining accurately. I get all 8 channels from the desk/summing mixer through to the BDA8 (green LED signal indicators on the front panel). But only the first four of those channels reach the Madiface (Channels 5/6/7/8 are nil/unresponsive).

I imagine it could be output from the card that is failing.

Re: MADIFace USB - Four unresponsive channels

In Totalmix : Only Input channels 1/2/3/4 receives signals from the AB8, Driver setting is 48kHz, correct ?
In this case, yes, it seems the AB8 is not sending half of the channels.
Are there any settings in the Mixer ? Sure everything is 48kHz ?

Yes I think the sensible thing is to pull this card and discount that possibility first. Thank you.

The BAD8 operates in 56 channel mode (aka 28 channels @ 96 kHz). Maybe there is a setting available to change that to 64 channel mode, like in the MF USB Settings dialog?
