Hi, Nancy.
Just a couple more tips.
Make sure the speakers to the sound system are installed in such a way that the CR will be able to hear clearly.
In our courtrooms we also have an infrared system so hearing impaired people will be able to hear the proceedings by using a headset. Each courtroom has several headsets in a rack. I grab one of those from time to time as it really does help enhance the sound. Especially telephonic conferences. Oh, maybe that's another thing - when we have telephonic conferences, the clerk sets it up so the sound is played through the courtroom sound system. It's usually pretty good sound, but those infrared headsets are quite helpful.
Also, when there's a bench conference, I have to put on headphones (not the infrared ones) and the attys/judge gather around a microphone that's installed at the side of the bench. The rest of the courtroom hears a white noise. I hear the speakers clearly - as long as they're near that bench mike.
We can also plug a cable into our computer's microphone jack to record the audiosync.
HTH.
