The Antelope Audio Isochrone Trinity is a master clock for your audio or video based studio. I've only worked at or even been to one studio that has this, and it's a very impressive piece home base for clocking. It boasts 64 bit DSP processing and full control inside the box with it's USB connection. Having only used this in a studio for a few days, I didn't exactly get the full experience of setting up the Isochrone Trinity, so I can't speak too much about the processing of getting it up and running. However, I will say that once this process is complete, you'll have yourself an incredible master clock for a long time. It does have all digital connections in the back in the form of AES/UEB for the most accurate connections possible. It will take up two spaces in a traditional rack case system. The amount of options and features here goes beyond what I would ever need it for, but just knowing that it's accuracy is to a T is enough for me to be a fan of it inside the recording studio. Something like this might not be for everyone, but if you're looking to be as precise as possible with your clock, the Antelope Audio Isochrone Trinity master clock will not steer you wrong. To list all of the great features found here would take way too much time, but do a quick Google search for yourself to get the full experience of everything Trinity has to offer. This seems to be Antelope Audio's most complete clock and while I don't know the exact price tag on it, I know it's not by any means cheap. Isochrone Trinity is definitely strictly for professionals and for those looking for the best universal master clock possible!
