Latency with Vinyl?

[Confused]

No idea where your 1 sec latency is coming from. A bit of an exaggeration perhaps?
It is well known that the latency on the optical input was originally around 160ms (confirmed to me by Devialet tech support) but was reduced in a recent firmware update to 80ms. Make sure you are on the latest firmware and Spark versions.

Well yeah, i might be exaggerating a bit, but not much. The Phantoms are brand new, got them like a week ago...shouldnt the firmware be the latest? If not, how do i check that and do the update? Is it with Spark? 

I have installed these in a cocktail bar, they sound and fill up the space great, but playing records (dj) with the latency was really not the easiest thing...

Massive noise cancelling headphones might help for cueing / mixing.  Or sell Phantoms and buy pro-audio kit.......

I know that back in my DJ'ing days the kit needed to be beer and drunken idiot proof, I'm not that confident that Phantoms would survive that long.  (Maybe you have a very classy bar?)
