I currently have a Rossini APEX DAC paired with a Rossini Clock. Recently, I added an Antipodes K22 server to my setup, which features an internal clock with clocked outputs. I am using the USB output from the K22 to connect to the Rossini DAC.
There is no option to turn the internal clock of the K22 off or to bypass it.
I would like to inquire whether this configuration might result in “double clocking” and if it could potentially lead to any errors or issues that may affect sound quality or sonic result.
If you are going USB from the Antipodes to the Rossini then you’re fine - nothing to worry about.
You don’t need to turn off the internal clock of the Antipodes as it needs that for its digital audio output, using USB will just use the Rossini’s clock source.
If you decide to swap to AES then the Antipodes doesn’t have 44.1 and 48k wordclock inputs so it would be impossible to feed it with clocks from your Rossini Clock … in that case I would set the sync for the AES input to “A” (auto / audio) and let the Rossini extract the clock from the AES input data.
Would that be the same advice for Ethernet feeds from NAS? I can’t think of any NAS units with word clock inputs. Melco N1 has a clock input but that is for 10mHz.
Pulling data via Ethernet is a totally different method of playback … in that case the input audio data is buffered and not transferred ‘in real time’ from the source.
When playing back data from the network your audio sync options are “M” (Master) where the Lina / Bartok / Rossini / Vivaldi uses its INTERNAL clock to sync playback to or, if you have an external clock that has 44.1 and 48k outputs, then you can set the audio sync to “W” to use the external 44.1 and 48kHz clock feeds.
I have changed the K22 to Oladra as per recommendations I received due to different clocking frequencies and different architecture.
I am still using AES.
To my understanding all of the Oladra’s outputs are clock / reclocked.
Can someone advise on the best way of connecting it to the Rossini Apex and Rossini clock?
The idea of using an external clock with an external player us the the same clock reference is used by both the player and DAC. That is, they are synchronised. To do this the player requires a wordclock input. However the wordclock connection on Oladra is an output not an input ( as far as I understand). So the Rossini clock cannot be connected to Oladra
@Phil has already told you this above in August ( note the need to set Rossini synch to “A” ):
You may find that not using Oladra as a player but in its other role as a storage unit and using the Oladra’s Direct Stream ( ethernet) connection ( try CAT5e cable) to Rossini DAC and with the Mosaic control point app could be preferable instead of AES. Of course your personal taste is the arbiter but if you haven’t tried I suggest that you do. Used for storage and not as a player the clock question regarding Oladra is then not important as it is sending the data file to Rossini DAC for processing where it is buffered on receipt.The Rossini Clock can be connected in the normal way with synch set to " W" as the DAC will then use the Rossini Clock as timing reference. Try it and see which you prefer.
