[QUOTE="kristianjohnsen, post: 106510, member: 441"] Re: 2x2 ADAT switcher/thru Hi Andy. I know it isn't exactly what you're asking, but here is a link to a cool company who's products I use sometimes, called Appsys. [url=http://appsys.ch/]Fresh digital gear...[/url] Basically, it's a line of devices based around ADAT connections. They make inexpensive ADAT spiltters, etc, and their main concept is to convert ADAT to a very robust electrical signal and send it over Cat5 cables, and then converting it back to ADAT. Needless to say, this is ideal for making inexpensive long runs with ADAT devices (we use them as "digisnakes" for various Yamaha mixers). Anyway, the electrical conversion of the ADAT signals and back is very straight-forward in a one-to one fashion where a 4-pair cable can run 4 ADAT streams, one for each pair in the cable. It would be very easy to DIY a switching matrix where you convert your ADAT streams to electrical, switch the electrical signals with any old switch, and then route them back into a converter giving you ADAT again. Depending on which unit you use you could easily paralell two ADAT converters on the electrical side, meaning you could avoid the optical wye-split, also. The only question I have would be how to avoid unwanted noises if you need to hot-switch ADAT streams that also carry word clock. I don't know if this would be a concern in this application. I will email Rolf at Appsys with a link to this site and ask him to join in. Best regards, Kristian [/QUOTE]
