What is the difference between the Omnia-6 EX and the Omnia-6 EXi?

The Omnia-6 EX and EXi differ in that the EXi adds built-in Diversity Delay (fully adjustable from 0-10 seconds) and a new LoIMD clipper to the "FM" channel. Both come standard with parallel processing paths and optimized final limiting for conventional "FM" and "HD".
