I am currently installing a paging system to work with the UC320 phone system. The Paging system is from Viking Electronics (PA-30) with 6 paging horns.
I currently have a night bell relay from my timeclock hooked up, and the system works great. Very loud.
When I connect the page out port of the UC-320 to the 3.5mm input jack on the PA-30, the paging works but is extremely quiet.
To troubleshoot, I connected an analog telephone to the PA-30 and tried paging from it. Works excellent, very loud.
I ensured the page volume was at full in the UC-320 web admin.
I called viking tech support. They say if the night clock tone is loud, the analog paging is loud, then there is an issue with the UC-320 source.
Is it likely I need a preamp from the UC-320? It's not like I'm going very far from the two units though. Only have a 16" cord.
So it would go UC-320 -----> Preamp -----> PA-30 amplifer.
