Topic: Digiface USB mix multiple sources

A question on my mind. Do I cause any signal loss if I would use Digiface USB for mixing various optical sources but where Digiface USB clock source is either it's internal clock or just one of the sources?

I made sure that all devices have their internal clocks set to 44100 Hz. (sources cd player, network player, AD converter)

Re: Digiface USB mix multiple sources

Everything connected needs to be using a common clock source. The Digiface USB does not have any sample rate converter inside to handle free running digital inputs.

Re: Digiface USB mix multiple sources

Agreed but how do you do that with items that have no clock inputs? Or is that simply a nogo ?

Re: Digiface USB mix multiple sources

It might be an idea for a future software/driver update to be able to select the Fireface USB Settings clock source via TM snapshots. smile

Re: Digiface USB mix multiple sources

It’s ok if you have one with no clock input as that can be master but if you have a few that only gave optical in then you can’t. Do they have bnc word clock? If they do you could use a converter to feed the others as master and then slave the others from that. Lots of ifs and buts. Better to have converters with both in and out.

Re: Digiface USB mix multiple sources

I've 3x device with only clock output an none clock input. Currently I routed via 4:1 optical box but I soon got tired of the button presses on the tiny remote thus wondered again could I (mis)use DF USB for this.

So now I've connected all to DF USB and can listen to all. Just to remember I have to manually self-select a clock source in the Fireface USB Settings app.
