I am trying to help this guy out and save the sale.
This is what I am going to send him
You of course can return the item to us for a full refund minus the shipping. I would first like to maybe help you get the item to do what you want it to do so you don't have to return it.
I am a mastering engineer and the person who we are selling the item for is also an audio engineer. Between us we have over 80+ years in audio. I guess we are both having trouble understanding what your usage is and why you are having problems. I guess the first question is would be are you sure that everything is properly terminated with 75 ohm terminations where needed? The second question is what types of “phase problems” are you having? The third question is why are you trying to adjust the phase? I am familiar with most of the equipment you are working with but have never had any phase problems using it. Can you tell me more about what the problems are so I can help you.Thanks in advance. Here is what I have been able to find on the WWW.
DSD
Selecting DSD will default to 44.1kHz reference. If no sync is available it will use the internal crystal
reference.
The interface requires a minimum of two BNC cables (DSD L and DSD R) to the DSD DAC.
The DSD output is switchable between SDIF2 and SDIF3 with the rear panel dip switch. SDIF2
requires a 44.1kHz sync signal to be passed to the DAC and this should preferably come from the
1073DPD sync output via a third BNC cable. SDIF3 transmits the DSD signals with clock
information included and should not need the sync signal.
Refer to your DAC for compatibility information.
That shows that:
- SDIF-2 is a 3-wire transmission, with a 44.1kHz wordclock (while the ESS waits for a bit clock) => a PLL is needed
- SDIF-3 is biphase encoded, thus doesn't need an external sync line. A PLL will be needed to extract the clock from the datastream.
This interface is based upon 75ohm BNC, unbalance transmission, 1channel in one cable and
externalwordclock(WCK).And its bitrate is 5.6448MbPS( f sdsd=2.8224Mbps) or
11.2896Mbps(fsdsd = 5.6448Mbps). Transmission is 1channel unbalance transmission and it
uses word clock as synchronization technique.
Thanks for the all the help so far.
