I've asked them by mail, I've got no idea how long before the actual shipping date of the DAC one would usually receive a notice from Okto.No news here either, #187 placed on 2020-07-29.
Update: Pavel says 2 weeksOrder #191 placed 2020-08-03 and no news.
Yeah, I don't really mind the long delivery time to be honest but I do mind the lack of communication and the misleading delivery time estimate*. That #191 is due for delivery soon gives me some hope for a delivery this year though, it'd make a nice christmas present for myself.I've asked them by mail, I've got no idea how long before the actual shipping date of the DAC one would usually receive a notice from Okto.
with spdif to AES cable.Hello,
is here anyone who runs the DAC together with a Minidsp nanoDIGI 2x8? I'm just wondering what kind of cable is the best to connect the devices together?
Greetings
I believe that was discussed in this thread before. Essentially you can get away with anything for short runs (~1m or so, I have no problems with ~3m at 48kHz). Otherwise look if you can find a second hand Canare BPJ-XP-TRA or Neutrik NADIT... somewhere.Probably the expensive cables with a conversion are necessary?
For short lengths the following will work fineHello,
thank you very much for the answer. There are different SPDIF on AES cable. Some have 75 ohms and others 110 ohms and there are also very expensive versions that convert from 75 to 110 ohms. Probably the expensive cables with a conversion are necessary?
@Octo Research
Maybe you could give some tips here?
That would certainly work, but is too complicated. AES inputs in the DAC8 PRO are terminated with 110Ohms as required by the standard, while the SPDIF expects 75Ohms. So a 220-240Ohm additional termination resistor will do the justice, since the digital receivers in the DAC8 PRO handle both SPDIF and AES voltage levels. But in fact, no resistor is needed at all if the cables are not very long. So a simple XLR M/RCA F adapter might work just fine in that case.

Yes, as already mentioned just a AES/EBU male to S/PDIF). I would look at the PRO (web)shops. Prices depend mainly on the quality of the connectors but should not exceed US$10 to US$20 for a good quality 1,5 meter cable. Shorter ones are sometimes harder to find. I use something like these at €12 (1,5 meter 110 ohm). BTW, Okto Research warns in the owner's manual not to use a balanced to unbalanced cable, but that's only relevant for the analogue output (DAC to amp). This can be confusing.Hello,

Hi, and thanks for the reply. I did not see it so I posted the Question again, sorry.Hi,
DrCWO here is the amixer output you requested, this is for DAC8PRO firmware version 1.4 connected to a raspberry pi 4b on raspbian buster:

The play back volume value can be changed via amixer command but this does not match or affect the DAC8PRO volume setting. Not sure this is normal ? I have not used amixer volume control before and am not very familiar with ALSA, is the amixer volume control separate from the USB DAC volume control setting ?
Volume control via usb would be very convenient.
