I have 5 x 4 way sennheiser IEM racks each with a 4 channel combiner. I'm planning to combine the 5 racks with a Sennheiser AC3000 8 way combiner. I don't have much experience setting up Sennheiser units in this way. I know from experience that with shure PSM 1000 systems I can link combines together for a single antenna output.

Any thoughts on what I'm trying to achieve? I won't have much access to the racks before day of the gig so I want to be prepared. Would there be any benefit to rewiring the whole rig to run directly from the 8 way combiner? I definitely don't want to have 5 broadcast antenna running at the same time, that would be asking for an intermodulation headache.

Thanks guys.
