We have many roomkits in classrooms this one room has been kind of stumping us despite not being much different than other rooms as far as size. They had issues with remote people hearing them, added a second mic still same thing, added another no change. I did a bunch of trial and error trying things like noise removal, de-reverberation on and off, a few levels nothing seemed to help. We tried a few things with the mics I had put in one was older square type, other was round type newer. Tested with my boss and he said one seemed to help some but other seemed like made it worse. Today I setup some temp mics ran all the wire below the drop ceiling, but mics on ceiling facing down. I tried these two mics and I think just one in front was marginally more clear but no louder.
I noticed these all default to zone 1, the tool tips says something about zones guide the unit in audio formatting but there is nothing I can find where you can draw zones for these mics and I also see nothing of if they can all be zone 1 or if should be different. I also thought from sounds of it maybe there was some document i never found that like zone 1 is generic, 2 is for presenter mic and 3 is for audience, etc. It seems everything I try doing with external mics the best pickup seems to be from the roomkit itself, maybe if right under a mic it is noticeably better. Also tried the external mics without the extension cable and did hardly anything. Also replaced the roomkit too thinking was maybe a hardware issue. We see no packet loss or other quality issues that would make think is network related.
Is there something I'm missing on these, all the other units seem similar gain settings around 14, all mics zone 1 no mention of issues in these other rooms.
