I noticed that the Multi Mic from ReSound only does wired streaming in mixed mono mode. Was wondering, “Why not Stereo?!!”
However, if the point is to use the Multi Mic as an Assistive Listening Device in public places, not to stream stereo music, it turns out that the best PA systems are MONO. The difficulty and serious problems of enjoying stereo broadcast sound in an auditorium are laid out in the following McSquared blog post:
I also found the Wikipedia article on “The Beatles in Mono” rather interesing-apparently, all their earlier albums were only put out in mono as it was in the days before stereo was fully developed. George Harrison’s comment on his initial reaction to stereo is most amusing:
At that time […] the console was about this big with four faders on it. And there was one speaker right in the middle […] and that was it. When they invented stereo, I remember thinking ‘Why? What do you want two speakers for?’, because it ruined the sound from our point of view. You know, we had everything coming out of one speaker; now it had to come out of two speakers. It sounded like … very … naked .
P.S. the other interesting point is that in normal listening, when you’re far away enough from stereo speakers, it’s effectively monoaural listening…
