Here's what Lavry support explained my options were for cabling - I can only assumed that XLR>RCA adapters would be wired "typically" and would not be easy to modify. I could be wrong though - I just did not have the time to investigate further. Although the below was for my req to switch between balanced and balanced without changing jumpers it should be helpful.
Again I'd advise contacting them with your specific reqs - they were very helpful for an XLR newbie like me. --------------- So; for unbalance operation without changing the internal jumpers of the DA10 set for Balanced Operation- YOU must wire the cable as follows (this is not typical of off-the-shelf cables)- the problem with using ready-made adapter cables or adapters is that they tend to have Pin1 shorted to Pin 3. The DA10 XLR connectors are wired for Pin 3 + or non-inverting. *With coaxial cable- single center conductor plus shield* Either: A.) Front panel switch set to Normal for normal polarity. -Connect XLR Pin 3 to the center pin of the RCA connector. -Connect XLR Pin 2 to nothing. -Connect XLR Pin 1 to the shield and the outer conductor or the RCA connector. Or B.) Front panel switch set to Invert for normal polarity. -Connect XLR Pin 3 to nothing. -Connect XLR Pin 2 to the center pin of the RCA connector. -Connect XLR Pin 1 to the shield and the outer conductor or the RCA connector. *With twisted pair cable- two center conductors plus shield* Either: A.) Front panel switch set to Normal for normal polarity. -Connect XLR Pin 3 to High signal conductor of the twisted pair and the center pin of the RCA connector. -Connect XLR Pin 2 to nothing. -Connect XLR Pin 1 to the shield and the low signal wire in twisted pair. On the RCA connector end, ONLY the low signal conductor of the twisted pair connects to the outer conductor or shell of the RCA connector. The Shield connects to NOTHING on this end. Or B.) Front panel switch set to Invert for normal polarity. -Connect XLR Pin 3 to nothing. -Connect XLR Pin 2 to High signal conductor of the twisted pair and the center pin of the RCA connector. -Connect XLR Pin 1 to the shield and the low signal wire in twisted pair. On the RCA connector end, ONLY the low signal conductor of the twisted pair connects to the outer conductor or shell of the RCA connector. The Shield connects to NOTHING on this end. The High and low signal conductors are somewhat arbitrary. Electrically, both wires are the same, so they are interchangable. There are some color combinations that are standard, but the important thing is that you are consistent in what color you use for which signal. For instance Red is usually High and Black is usually low. The only reason this wiring approach would be necessary is to allow you to switch between balanced and unbalanced operation by changing the cables that plug into the DA 10. An alternative is to set the DA 10 for unbalanced operation using the internal jumpers, and feed the balanced input with an unbalanced signal. You would still retain the hum-rejection properties of the balanced input, but would loose 6dBs of level and thus 6dbs of total possible signal-to-noise ratio. -------- -- mr-b ------------------------------------------------------------------------ mr-b's Profile: http://forums.slimdevices.com/member.php?userid=10044 View this thread: http://forums.slimdevices.com/showthread.php?t=39209
