Ok, another question. I am looking to try to install a real comm system and move away from the (home licensed) two way radios that we use. I've come up with three proposals and I was looking for professional opinions. Option One: --Clear-Com MS 702 $1,100 --2 Clear-Com RS-601 Belt packs $300 ea. --1 Clear-Com RS-602 Belt pack $400 ea. --4 Clear-Com CC-40 Headsets $190 ea. Option Two: --Telex MS-2002 $900 --2 Telex BP-1002 Belt packs $250 ea. --1 Telex BP-2002 Belt pack $350 ea. --4 Telex HR-1 Headsets $200 ea. Option Three: (BIG THANKS TO [USER]VAN[/USER] (and the search function) FOR THIS COMPANY) --Production Intercom MS-200 $800 --2 Production Intercom BP-1 Belt packs $230 ea. --1 Production Intercom BP-2 Belt pack $330 ea. --4 Production Intercom SMH310 Headsets $100 ea. I think I will recommend the PI system because I've used one of their systems before and I've found it to be decent quality at a great price. My main questions are: Will all these systems work as is? Or am I missing something? I wasn't sure about a power supply, because from the specs it looked like each of these master stations can handle more belt packs than what I need. Basically, I'm looking to start out with four headsets and eventually expand to 8-10 with an additional two speaker locations backstage. Can I upgrade to wireless with any of these systems? I think I can with the Clear-Com system, but as for the other two, I'm not sure. (I gather I can with all of them from reading older threads, but no specific systems were mentioned.) For Installation, should I recommend a pro install? I've never worked with these kind of systems before, so while I think I could do the install, I'm not exactly sure of the specifics, like what type of Cable to run and how to install it for multiple belt packs. For instance, do I run one cable per channel and daisy-chain? Do I need a splitter and run multiple cables? I'm not really sure how to set it up, and the diagrams I've seen on Clear-Com's website haven't helped me that much. Thanks for any help.
