Or vice versa.
Is there cables for this that you recommend (db25)? Any problems one need to know about? Is there any problems with balanced/unbalanced in the digital world that might cause problem?
I'm not good at this so any recommendations is very appreciated.
Im going out from a RME card to a digital patch that's already finished.
You might have a better chance of getting a helpful response if you supplied some specific info. There are dozens of RME interfaces and cards with various digital I/O connections including multiple ADAT, AES/EBU, and S/PDIF. These are industry standards. Many of those are physically implemented using balanced digital cables of specific impedance (110 ohms) and voltage swings. Not to mention the TOSLINK optical standard for ADAT audio.
Just saying "yamaha?", "tascam?" and "RME" is not enough info. The digital DB25 connectors on most Tascam and Yamaha gear are balanced AES3 connections plus multiple grounds. The digital signals are fully compatible (each AES3 channel can carry (2) audio signals), but the pin-outs are completely different between the brands, so the cables must be wired accordingly.
Tascam, Digidesign/Avid and Lynx (and, I believe RME 8-channel) share the same pin configuration and Yamaha, Apogee, Sony and Mackie share the other pin-out. Of course, all are fully balanced and impedance matched. You must
be certain you are using the right cable configuration. A Tascam to Tascam cable will not
work as a Tascam to Yamaha cable. Mogami and others do make "format crossover cables
" to do that.
