PA / Video Systems at Michigan Stadium
As we approach the third anniversary of the completion of the $226 million stadium expansion project, I have another web find to share with the community of some of the upgrades that went into it, as I have reported here periodically when I have come across the info on the web. This time, it’s on the PA and video systems. I'm not an audio or video technician, just a fact finder passing along perhaps some interesting information.
The PA system includes 28 Meyer Sound MILO 60 line array loudspeakers, eight SB-3F sound field synthesis loudspeakers, four MSL-4 loudspeakers, a Galileo loudspeaker management system with two Galileo 408 processors, and an RMS remote monitoring system.

Too bad we don't have Denard around any more. He could have carried the signals...
Loud speakers at both endzones would create a really annoying echo since most spectators would not be equidistant from the speakers. An alternative to loud speakers would be many smaller speakers spread around the stadium (think Comerica Park). As long as the speakers aren't loud enough to travel across the field there wouldn't be echo. The problem with that system is there is no place to put speakers in an open air bowl stadium.
You know moar words then me.
The impressive thing is the sensitivity. I believe these are about 550 watts per loudspeaker, but have a sensitivity of 140 dB. For reference, a high-end home speaker has a sensitivity of about 90-95 dB. A speaker that gains 3 dB in sensitivity requires half the power to drive them at an equivlent sound level, A typical PA or concert loundspeaker might have a sensitivity of 110 dB, which means these speakers are extremely efficient. Caveat this that the primary drivers I'm talking about sacrifice low-frequency for their size and efficiency, and all of this really means nothing about loudness.
I glanced at the title on the board and came away with something about the sound systems in the PA and Michigan Stadiums.
I'm confused. Is this some kind of an upgrade, or are you just recapping what was put in place years ago?
Meyer Sound is as good as it gets. Must be some crazy wattage.
Any chance we ever get any color on those boxes? I don't believe the new paint job includes it, right? I just kinda think it looks a little bland. Even just throwing up all the years of conference championships or NC or retired numbers, or even just the name of the stadium in maize. Anything to get some color on that thing would really make it stand out.
Legacy numbers then, All American's whatever. The point is to get some color on there. It just looks a little drab.
Too bad The Victors sounds like three different bands playing a round on TV.
I am told that the sound is only broadcast from the north because it would cancel otherwise. Does that make sense to anyone?
I am at the top of the south endzone, the greatest distance from the speakers and video board (can't see the one at the south) so sound is way off and the stats are way small. But I can stand or sit as I like!
I sit in the lower portion of section 4 and almost regularly had a hard time hearing the band, especially when the opponent brought theirs (which is/was nearly every time) or when there was a lot of cheering (after a TD, turnover, etc.). I'd have to imagine that folks in the SW corner really had a hard time hearing the band.
I can the hear them now, but as has been mentioned by most, it does sound about half a beat off at times, due to the echo.
to me the band had become a myth. I remember them being there in the past, but was never sure if they were still there.
is there really an efficient way to get noise into the ears of 110,000 people at the same time in a space that large.
