I'm using 2 of these to connect my Behringer UMC1820 to my ADA8200, expanding the UMC to 16 channels in, 18 out. I've mainly used it to record on the extra ins. Has so far worked flawlessly and I've used it to track 16 channels of drums for over 10 hours straight. No audio issues. The cable(s) are very small which helps reduce clutter at the back of my rack.
Great branded cable. Remember these are stiffer than some other toslinks. Thumbs up for short contacts with very good grip, they seem to be casted in one piece so they dont fall apart then u have to pull them hard out(like some other cheaper designs. Half a meter is a really short cable I found out :) Can recomend these.
I use mine to contact my Focusrite 18i20 to my Behringer ADA8000. The original cables I had were lose and would fall out during transity. Not these, snug as a bug! Been using them for 7-8 years or so now and no sign of failure yet.
I recently got the Prism Lyra 2 and now I can connect my Focusrite Scarlett 18i20 to it with these cables and get an extra 8 ins and outs via ADAT. Works perfectly, and good quality build cables, slots firmly in place.
