‘I had an interesting situation with a client who demanded to have a “surround sound” coming from one voice speaking from a lectern, and when I tried to explain that the monaural clarity of the voice at all listening points was the ideal goal, she puffed up her hubris and found me “argumentative.”‘
Some people can’t handle being told anything other than what they want to hear. Perhaps the thing to do is avoid the explanation and just say “yes ma’am”. In this case, if the venue had (or could have been set up with) rear speakers, she may have just wanted to be sure people in the back or balconies could hear her. You could have measured the distance, ran the numbers, and gotten away with inserting a simple delay line to them … everything is still mono (as opposed to creating an actual surround sound network). I can’t see how she would ever know the difference.
The church I spoke of has a 32ms delay line to the ceiling speakers (I abhor ceiling speakers, but…) in the gathering room, which can be used for overflow (Christmas, Easter, etc.), i.e., folding doors open it to the sanctuary. The community theatre is about the same with side speakers aligned with the last few rows and the balcony.
