I have been wanting to upgrade my dj setup to digital quality sound and can not overcome a not conveying s/pdif signal. Over a short 75ohm COAX cable that is.
In short:
Source: 2007 SynQ CDX.2 double CD-player with 2x S/PDIF OUT over coax (from each CD tray)
Mixer: 2019 Pioneer DJM-V10 LF with 6x S/PDIF COAX IN on coax
Problem: no digital transfer, unless briefly on the moment of switching the input knobs on the Pioneer mixer, from 'Digital' to 'PC B'.
Performed Tests:
* sending the SynQ CDX.2's coax signal to a YAMAHA RX-A780 receiver: works fine, sounds clear, even altering pitch sounds fluently = OK
* sending Creative Soundblaster Audigy 2 COAX to Pioneer DJM-V10 mixer: works fine, and sounding very clear = OK
* sending SynQ CDX.2 COAX to Creative Soundblaster Audigy 2 over COAX: no sound, regardless the frequency 44.1;48, 88.2 or 96kHz = NOK
Tried solutions:
* shorter 75Ohm cable (50cm)
* sending the SynQ CDX.2 s/pdif COAX over an Audiophonics Digirescue 'Reclocker' (which buffers but does not alter frequencies) to the Pioneer DJM-V10
* changed other intern 8-pins miniDIN cable which connects the SynQ double CD-platter module with its control unit; since it seemed reverse engineered (other story)
* opened up the player to find out about the OEM circuit boards, codes and empty jack busses
which one is to blame:
* status bit
* copy bit
* jitter
* dithering
* biphase code
* no clock in sending signal (maybe Yamaha receiver design doesn't care about too much, and accepts it all)
* something's not locking, but on what ?
Read about/considered solutions:
* Behringer SRC 2496, but has only one COAX IN and only one COAX OUT
* Sonifex redbox rb2-sc but awfully expensive (IF it solves the issue)
Given:
* guess you're aware about Pioneer DJM-V10 since it's 'recent' design.
* SynQ CDX.2: one might be not that familiar with these, since it's a 2005 Belgian dj gear evolution of JBSYSTEMS' MCD680, along different not-totally-professional OEM double CD-players from that era, as we know Gemini, Numark, American DJ, Omnitron... because the DENON DN-2000F was too expensive for most starting bedroom dj's.
No luck with:
* BEGLEC: distributor still active in Belgium for it's woofers and (still) SynQ TRM-001 4kN start pickup, but not interested: "The digital signal goes parallel with the analog signal" ??
* Pioneer: frontline helpdesk goes all defensiveand keeps asking about analog connections even after explaining the whole digital story with pictures & video
* Reading through forum discussions, I'm hoping a specialist site like this knows what I'm talking about, to point out maybe which machine is determining the clock. Maybe no clock is embedded ?
Admit:
* Back in 2007, the SynQ CD-player shop seller warned me about the digital signal never going to sound over s/pdif COAX on a Soundblaster Creative Audigy Sound Card.
I'd have to buy some apparatus to put inbetween (but I don't remember what type)
Nevertheless I hoped - 20 years of evolution later- a professional > €3000 Pioneer mixer -obviously designed for the same dj purpose - might do the trick. Unfortunately not.
