I want to send balanced audio from one room to another in my home. The audio will originate from a Soundcraft Spirit Folio 12/2 mixing console desk.
I'm assuming that the mix left/right and/or aux 1/2 outputs from this desk are balanced - but I'm not sure (so I've asked a seperate question above this here: What Soundcraft Spirit Folio 12/2 mixing desk/console outputs are balanced? ).
If they're not, I would connect them to a Behringer Ultra DI DI20 box and attach 2 balanced cables I have already laid to it. I have done some tests already that indicate that the signal sent is good quality with very low noise.
At the other end, I want to feed the audio input as RCA phono stereo pair into a Technics HiFi amplifier. For this:
- can I use cables that 'convert' balanced to unbalanced? (e.g. https://www.amazon.co.uk/Pseudo-Balanced-Phono-Damme-Starquad/dp/B01MRZ21TO or https://www.canford.co.uk/CANFORD-BALANCED-TO-UNBALANCED-CONVERTERS )
- Can I assume that such cables are bidirectional in that if they are listed as unbalanced to balanced, they will also do it the other way around?
- Or should I consider a 2nd small mixing desk to do the conversion. I haven't found one that provides unbalanced output. For example https://www.soundcraft.com/en/products/notepad-5 - nice mixer,
but balanced only outputs it seemsCorrection: They also have unbalanced output in the form of a stereo 6.35mm jack output.
I guess that converting balanced to unbalanced might be simple enough to implement in a cable. After all, the sound ultimately ends up that way by summing the +ve and -ve (mirror images of the sound), to cancel out the same noise signal by inverting one of the signals before summing.
Thanks for reading and any input appreciated.
