Just demoing a Streamer with a USB connection to my Bartók. The input button on the front panel when pressed says, USB 1 which is correct, but it will not allow me to scroll through the inputs. Which I thought it would?
I have unplugged the Bartók and rebooted it, but it’s still stuck on USB 1.
I just gave the Bartók an Ethernet connection, then changed the input in Mosaic. Once I’d done that I was able to charge the input on the front panel.
That doesn’t seem right, is it
I hope that I understand your issue.
Have you got anything connected to other Bartok inputs? Although I do not have Bartok from memory all of the other dCS DACs I have experience of do not display unconnected inputs.
All dcs dacs when you use the front button on the dac will only give you any connected inputs that are on.
So if say you have a cd player plugged in using aes and then say your streamer on usb, if are using the streamer then it will be available but if the cd player isn’t switched on then it won’t be seen, turn it on and then both will be available to select on the button.
If you use mosaic all the inputs are shown even if nothing is connected to them, let alone if they are and just not powered on. I guess the input isn’t seen until its got something powered on infront of it.
Anyway hope that helps
Hi Pete
Yes, I have SPIDF 3 connected.
Just tried it again and the front panel button now works. I can select any input now.
The scenario appeared to change when I changed the input in Mosaic. Which is weird.
Update: Just disconnected the Ethernet cable from Bartók, now unable to change input on the front panel. Stuck on USB 1.
Hiya Dunc
I think you may of sussed it.
USB 1 is connected to a Streamer.
SPIDF 3 is connected to a TV.
At the time of pressing the front panel button, the TV was off. So it only displayed USB 1.
Just switched the TV on and now the front panel shows SPIDF 3 as well as USB 1.
So, I’m thinking the Bartók is okay 
Very much so. Thanks Duncan
All is fine, don’t worry
As others have already said, the Bartók will only show currently active inputs as available. USB1 always shows as active as the USB XMOS is always active and talking to the FPGA, so even if no USB device is connected that’s the one input that will always be available.
You can set the Bartók to the desired input even if it is not active via Mosaic, should you need to.
Thank you James.
