Both Clear-Com and Pro Intercom partyline master stations have connections for single channel 2W intercom (which is essentially RTS ch B), line level in and mic level out, and can accommodate a goose neck mic.
If you have a matrix com system, all the key panels have aux I/O and speakers.
thanks henry,
i always thought clearcom's panel (and subsiquent box enclosure) had to have 2w com knew they made a 2 ch version and a standard 1 ch version ... after reading your post i did some further investigation and they actually make a 4w board for their small wall panels which is perfect ... few screws and it turns the standard 2w variants into 4w boxes !! runs off 20-30v dc or an ac option as well.
this is really what i wanted because in this situation they system is all analog partyline 2w, 1 wireless interface and i can use that to get a 4w port to extend over the existing cobranet and fiber ... if things change in the future the box can still be used in either 2w or 4w with a small change.
I think it was said in a different post but this forum is an amazing place ... what other industry can you get to have a conversation with true leaders of the field we are discussing!
